The Superintendent’s Compendium is the summary of park specific rules implemented under Title 36 Code of Federal Regulations (36 CFR). It serves as public notice, identifies areas closed for public use, provides a list of activities requiring a special use permit or reservation, and elaborates on public use and resource protection regulations pertaining specifically to the administration of Isle Royale National Park.
This Compendium supersedes all previous releases. All prior releases are rescinded.
Paper copies of the Superintendent's Compendium may be requested at park Visitor Centers. Download a digital copy here: Superintendent's Compendium (462 KB).
Introduction
The purpose of the compendium is to provide the public and park employees with a document that lists the special designations, closures, public use limits, permit requirements and other restrictions imposed under the discretionary authority of the Superintendent. The authority to implement these designations, closures, use and activity restrictions, is found Title 36 Code of Federal Regulations (CFR) §1.5(a). Other sections of 36 CFR provide the Superintendent with discretionary authority as outlined further in this document. The compendium actions in this document apply to all persons entering, using, visiting, or otherwise within the boundaries of federally owned lands and waters administered by the National Park Service (NPS) as part of Isle Royale National Park (the park). Other applicable regulations found in the CFR and United States Code (U.S.C.) are enforceable without further elaboration at the park level. The Code of Federal Regulations and U.S.C are available online at http://www.ecfr.gov/ and http://uscode.house.gov/.
The Park intends that this compendium, in conjunction with park brochures, maps, signs, and other media, provide a clear understanding of park regulations to ensure adequate protection of the park’s resources and provide for public safety and enjoyment. The closures and restrictions delineated in this compendium do not apply to official/administrative use or applications (36 CFR 1.2(d) and 1.5(a)). Additional guidance for park residents is provided in park policies, including the Housing Management Plan. Many requirements of this compendium complement existing state and local law and regulations which are also in effect within the park. If a state or local law is currently enacted, this compendium does not replace or repeal that law.
A person who violates any provision of the regulations found in 36 CFR Parts 1-7, along with this compendium, is subject to a fine as provided by law (18 U.S.C. 3571) up to $5,000 for individuals and $10,000 for organizations, or by imprisonment not exceeding six months (18 U.S.C. 3559), or both, and shall be adjudged to pay all court costs associated with any court proceedings.
The Compendium is reviewed annually and revised as necessary. Changes were made to food storage requirements in July 2024. The park welcomes comments about its program and activities at any time. Inquiries regarding NPS regulations, discretionary actions, requests for permits and comments about this compendium may be directed to:

36 CFR Part 1 – GENERAL PROVISIONS
The specific discretionary authority for Park Superintendents to establish reasonable schedules for visiting hours, impose public use limits, and close park areas for all public use or specific use is found at Title 36 Code of Federal Regulations (CFR) §1.5. These park-specific restrictions are also based upon 36 CFR, Chapters 1-7 to protect park resources, visitors and employees. Under CFR §1.7 notice of all restrictions, closures, designations and permit requirements will be made available to the general public by a least one or more of the following methods of notification: maps, brochures, signs, permits, or other appropriate methods, as well as within this compendium.
36 CFR §1.4 Definitions
Some terms used in this Compendium may have specific meaning defined in 36 CFR 1.4 Definitions. In addition to definitions found in 36 CFR § 1.4(a), the following apply to all parts of this Compendium:
Archipelagomeans a group of islands closely scattered in a body of water. Isle Royale National Park is an archipelago with approximately 400 islands.
Artificial luremeans a man-made fishing lure manufactured to imitate natural bait. Artificial lures include spoons, spinners, flies, and plugs made of metal, plastic, wood, and other non-edible materials.
Barbless hook means a hook manufactured without a barb or a hook whose barbs have been filed, closed (point of the barb has been crimped or pinched so the barb touches the hook shank), or has otherwise been completely removed.
Catch and release means a fish must be carefully and immediately returned alive to the water from which it was taken.
General Management Plan/Final Environmental Impact Statement (GMP) was approved by a Record of Decision, signed May 11, 1999, by the Midwest Regional Director of the NPS. The GMP established park zones with specific provisions authorized or restricted in those zones. The zones were established to protect park resources and the wilderness values sought by most park visitors. The full GMP may be referenced online at: https://ia800609.us.archive.org/12/items/finalgeneralmana00roya/finalgeneralmana00roya.pdf
Ozaagaateng means “the place the light shines outward” in the Anishinaabe language. The NPS is working through the Board of Geographic Names to formally change the location name of “Windigo” to “Ozaagaateng,” and expects that to be complete when the Compendium is updated in 2025.
Park Resident means an NPS, concessions, or partner agency employee, contractor, or volunteer and their family members and/or invited guests.
Seaplanemeans an aircraft with floats that lands on water or an aircraft with amphibian floats (floats with retractable wheels) that can land on water or land.
Unmanned aircraft means a device that is used or intended to be used for flight in the air without the possibility of direct human intervention from within or on the device, and the associated operational elements and components that are required for the pilot or system operator in command to operate or control the device (such as cameras, sensors, communication links.) This term includes all types of devices that meet this definition (e.g., model airplanes, quadcopters, drones) and are used for any purpose, including for recreation or commerce.
36 CFR §1.5 (a)(1) Closures and Public Use Limits
Closures
Seasonal Closure
All islands, including the main island of Isle Royale National Park, are closed to public use from November 1 – April 15.
Determining Factors: This seasonal closure is necessary for the safety and protection of visitors and emergency responders due to extreme weather conditions. This closure is being evaluated in a 2023-2024 Wilderness Stewardship Plan Environmental Impact Statement (EIS) process.
General Closures
Rock Harbor Lighthouse
The Rock Harbor Lighthouse tower is closed to all public use.
Determining Factors: This restriction is necessary for public safety due to damage to the stairwell (including rotting stairs). The Park plans to replace the stairs in future years.
Rock of Ages Lighthouse Dock
The Rock of Ages Lighthouse Dock is currently closed for all visitor use.
Determining Factors: This restriction is necessary for public safety after deterioration and storm damage made the dock unstable and unsafe. The dock may be used for official purposes, including work by the Rock of Ages Lighthouse Preservation Society. Dock replacement is anticipated to begin in 2025.
Cross Country Zones Impacted by the Horne Fire
Off-trail areas impacted by the Horne Fire are closed to cross country camping and travel. A map and information on restrictions and closures for each zone can be found at park visitors centers and on the park website: Cross-Country Camping Zones (nps.gov).
Determining Factors: This restriction remains necessary for public safety in burned areas where there is significant downfall and risk of falling trees or branches, flooding, and erosion.
Administrative Roads
Administrative roads on the island are closed to public and personal motor vehicle use. Official NPS, concessioner, park partner, and contractor administrative vehicles approved by the Superintendent, are authorized for administrative use only on designated administrative roads. Vehicles used for accessibility, such as a golf cart, must be approved by the Superintendent. Motorized wheelchairs, mobility scooters, and other similar accessibility devices do not need approval in non-wilderness areas.
Determining Factors: This restriction is necessary for public and employee safety. There are no designated public roadways or highways on the Island.
Housing
Government and concessionaire employee housing areas and recreation halls are closed to public access. This does not include guests of employees.
Determining Factors: Restricting public access to government and concessions employee housing areas provides improved security and privacy to residents and their families while not adversely impacting park visitors.
Administration Facilities, Maintenance Facilities, Utility Areas, and Equipment
All administrative buildings are closed to visitor entry. This includes but is not limited to historic structures closed to the public, and all administrative and maintenance facilities, such as shops, sheds, and offices.
Utility areas and utility/operational equipment are closed to visitor access and use. This includes solar panels and batteries, communication buildings, radio tower structures (excluding fire tower stairways open to the public) and antennas, fuel storage tanks, fuel system access, fuel containment areas, maintenance machinery and equipment, heavy equipment, and NPS vessels (except public areas of the Ranger III ferry when authorized during passenger season operations).
This shall not apply to persons in non-public areas who have been granted specific permission by the NPS, another authorized Federal agency, concessionaire, or their representatives, or those who are under escort of park employees acting within the scope of employment.
Determining Factors: These restrictions are necessary for public safety and the protection of infrastructure and equipment. Restricted access allows employees to safely conduct work in non-public areas.
Public Use Limits
Maximum Occupancy
The number of visitors authorized inside facilities such as visitor centers, restrooms, stores, lodge office, restaurant, laundry facilities, historic structures, museums, and exhibits may not exceed the maximum occupancy if posted. Entering or remaining in any of these locations after being asked not to enter or to leave the location because the maximum occupancy has been reached is prohibited.
Determining Factors: This order will be revised as necessary to remain consistent with federal, state, and local guidelines to maintain public health and safety.
Docking and Mooring Areas
All or portions of park docks may be closed to public mooring according to this schedule, or as posted during the passenger ferry season. All times are listed in Eastern Daylight Time (EDT).

Any other dock posted as closed to public entry
Shipwreck America is closed between the hours of 10:00 am and 12:00 pm EDT between June 1 and Labor Day.
Determining Factors: Mooring restrictions are necessary to ensure safe access for concession vessels that provide scheduled visitor transportation services and contractors that perform a variety of required Government projects or functions. Some docks or portions of docks are closed to ensure the safe and effective use, operation, maintenance, and administration of the park. Docks may be closed temporarily for public safety during construction. Dock closure and mooring buoy information is online at https://www.nps.gov/isro/planyourvisit/conditions.htm.
Boating and Aircraft
All inland lakes and streams are closed to the use or possession of motorized vessels and aircraft. The Chickenbone Lake outlet, an unnamed stream between Chickenbone Lake and McCargoe Cove, is closed to all vessels including paddle craft.
All vessels (including non-motorized craft such as canoes and kayaks), motors, and trailers transported to the park via the Ranger III (or other vessels) must be decontaminated prior to being loaded for transport to the park. Decontamination can be accomplished by any of the following:
Clean and dry watercraft, and/or all associated gear and equipment so they are dry and free of any vegetation, animals, and mud, and that the bilges, live wells, and other compartments are also clean, dry, and free of all organic material. A minimum of 5 days of drying before loading is required.
Wash the vessel, bilge, and equipment with >140º F and/or high-pressure water.
Wash the vessel, bilge, and equipment with disinfectant. Follow manufacturer requirements for disinfectant treatment time frames.
All vessels (including non-motorized craft such as canoes and kayaks), motors, and trailers visiting or transiting within park boundaries must be decontaminated prior to entering the waters of the park. Decontamination can be accomplished by any of the methods described above. If the vessel is large and not be trailered, or below the water line is not visible, the vessel owner/operator shall inspect the vessel hull, outdrive, trim tabs, and motors for attached Aquatic Invasive Species prior to entering park waters. All vessels, regardless of size or configuration, are subject to inspection for Aquatic Invasive Species at the island. Vessel owners are responsible for Aquatic Invasive Species decontamination prior to entering park waters.
Determining Factors: These measures protect park resources and prevent the introduction and spread of Aquatic Invasive Species and disease including Viral Hemorrhagic Septicemia Virus (VHSv) into Lake Superior or the park’s inland waters through transport via water, mud, etc.
Use of Electronic/Mechanical Devices and Generators
Electronic/Mechanical Devices in Developed and Motorized Zones
The audible use of electronic devices such as stereos, televisions, radios, cell phones, tablets, and similar devices is allowed only within the Developed Zones of Windigo/Ozaagaateng, Rock Harbor, and Mott Island and the Lake Superior Open Water Motorized Zone (areas not designated as Quiet/No Wake Zones), subject to the requirements of 36 CFR 2.10(b)(4) Camping and Food Storage, 2.12, Audio Devices, and 2.34 Disorderly Conduct. Park residents in housing units located within Quiet/No Wake Zones may operate electronic devices if the noise associated with such devices is quiet enough that it cannot be heard beyond the immediate vicinity of the residence.
The use of marine band radios and other emergency communication devices is allowed within all areas of the park; however, non-emergency communication use is subject to 36 CFR 2.10(b)(4), 2.12, and 2.34.
Electronic/Mechanical Devices in All Other Areas Including Quiet/No Wake Zones
The audible use of electronic devices such as stereos, televisions, radios, cell phones, tablets, and similar devices is prohibited in all other areas of the island not listed in the authorized bullet above (approximately 99% of all terrestrial areas) and in Quiet/No Wake Zones. Information on Quiet/No Wake Zones is found at https://www.nps.gov/isro/planyourvisit/quiet-no-wake.htm.
Portable Generators
The use or operation of a portable generator is prohibited within the park except:
While underway in the Lake Superior Open Water Motorized Zone.
When moored at any shipwreck mooring buoy within the park, between the hours of 6:00 a.m. to 10:00 p.m. EDT. Shipwreck buoys are to be used only by divers with a valid permit during actual dive operations.
At the Washington Harbor and Snug Harbor public docks between the hours of 8:00 a.m. to 12:00 p.m. (noon) and 3:30 p.m. to 5:00 p.m. EDT.
The far west end of Florence Bay, Glenfiddick Bay (west and north of Duncan Bay), and the unnamed southwestern arm of Five Finger Bay (between Stockly Bay and Duncan Bay), between the hours of 8:00 a.m. to 5:00 p.m. EDT.
Determining Factors: These actions promote a quality visitor experience by protecting resources and providing relatively tranquil, natural marine and/or wilderness surroundings consistent with the values enunciated by the Wilderness Act, GMP, and other applicable law and policy.
On-board Vessel Generators
The operation or use of a permanently installed on-board vessel generator is prohibited at the following public dock locations:
Birch Island
Chippewa Harbor
Daisy Farm
Duncan Narrows
Duncan Bay
McCargoe Cove
Merritt Lane
Moskey Basin
Three Mile
Todd Harbor
Tookers Island
Siskiwit Bay
Operation or use of a permanently installed (by the boat manufacturer) on-board vessel generator is allowed in the Lake Superior Open Water Motorized Zone and at boat docks otherwise open and available for public camping or overnight use, subject to the requirements of 36 CFR §2.10(a)(4), 2.12, and 2.34.
Operation or use of a permanently installed on-board vessel generator is allowed by vessels at anchor within Hay Bay and at anchor within other Quiet/No Wake Zones except when anchored within 1/4 mile of a designated park campground (see Boating and Water Use Activities, Section 3.6 – Prohibited Operations).
For overnight dock use, see camping conditions in 36 CFR §2.10.
Determining Factors: All docks where generator use is prohibited are located close to primitive campgrounds. A generator operated at these docks would be clearly audible in the adjacent campgrounds. This action reduces the impact of mechanical noise on visitors camping in or otherwise using Wilderness and/or non-developed areas of the park. The action promotes a quality visitor experience by providing relatively tranquil, natural marine surroundings.
Fishing
State regulations apply unless otherwise specified below. See also 36 CFR §2.3:
Fishing on Lake Superior Waters
Transporting fish or fish parts to the park for use as bait is prohibited.
Possession or use of fish as bait within the Lake Superior waters of the park is limited to fish and or fish parts taken from fish that are caught using lawful fishing methods within Isle Royale National Park waters during a current visit. Use during subsequent visits is prohibited.
Brook trout within 4.5 miles of Isle Royale (see additional inland water information below) are catch-and-release only; no possession is allowed
Fishing on Inland Lakes, Streams, and Rivers of Isle Royale
Method of take; all species:
Live, dead, or preserved bait or organic food may not be used or possessed at any time.
Only barbless hooks may be used.
Only artificial lures may be used.
Determining Factors: The use of fish, fish parts, or roe (fish eggs) for recreational bait fishing is a means by which Aquatic Invasive Species and diseases such as VHSv can be transmitted to new populations of fish. Bait and lure restrictions protect fish from disease transmission. Barbless hooks are easier to remove and minimize damage to mouth parts, gills, etc. of fish, which is especially important to any fish that doesn’t meet size requirements or fish being caught and released.
Regulations for the following species apply to inland waters of the park:
Brook Trout
Season: Last Saturday in April through Labor Day.
Catch-and-immediate release only
Determining Factors: Annual surveys in the park show the coaster brook trout has extremely low population numbers. Isle Royale National Park is home to two genetic variants of coaster brook trout. These are believed to be some of the last viable native coaster populations in the Great Lakes. These restrictions protect the remaining population.
Rainbow Trout
Season: Last Saturday in April through Labor Day.
Size Limit: Minimum size is 7 inches.
Daily catch and possession limit of five fish.
Determining Factors: Rainbow trout utilize the same spawning streams as coaster brook trout at Isle Royale. One of the limiting factors for coaster brook trout viability at Isle Royale is suitable spawning habitat. Rainbow trout compete for limited spawning habitat and food for fry and fingerlings in the streams and may also prey on brook trout fingerlings. A minimum size limit of 7 inches maximizes the opportunity for anglers to take rainbows without jeopardizing brook trout (at smaller than 7 inches, trout species often are hard to distinguish from each other). A daily possession limit reduces additional fishing pressure in these streams and subsequent unintended impacts.
Lake Trout in Siskiwit Lake
Season: April 16 through October 31.
Size Limits: Minimum size is 15 inches, but not more than one 34” or greater.
Daily catch and possession limit of three fish, but not more than one 34" or greater in possession.
Determining Factors: Inland lake regulations for lake trout are a combination park and state regulations in Keweenaw County. The seasonal dates reflect the park’s operating season. Current population data does not support higher daily possession limits.
Northern Pike
Season: May 15 through October 31.
No minimum size: maximum size is 30 inches.
Daily catch and possession limit of two fish.
Determining Factors: To protect the most productive northern pike spawners, an upper limit of possession of 30” is in effect.
Lake Herring (Cisco) and Lake Whitefish (Coregonus sp.)
Season: April 16 through October 31.
No size limit.
Catch and release only; no possession is allowed.
Determining Factors: The inland lake populations of cisco are currently at the point where harvest may cause local extinction of the species. The catch and release designation for ciscoes and whitefish (all Coregonid species) in the park’s inland lake waters reflects concerns over the very low populations within these lakes. This action does not limit fishing in the Lake Superior waters surrounding Isle Royale.
Diving
The following areas are closed to diving:
Passage Island Cove.
Inland lakes.
Shipwreck America between the hours of 10:00 a.m. and 12 noon EST between June 15 and Labor Day.
Wreck mooring buoys:
Shipwreck buoys are to be used only by divers with a valid permit during actual dive operations.
No more than two vessels are to be moored at any one time.
Overnight mooring on buoys is not allowed.
All SCUBA diving equipment, regardless of dive locations prior to arriving at the park, must be decontaminated and clear of aquatic nuisance species before diving in park waters. This can be accomplished by the following:
Soak all dive equipment in a chlorine solution of ½ ounce bleach per gallon of >140º F water for 10 minutes and then rinse with tap water, OR
Allow dive equipment to dry thoroughly for at least 14 days ensuring that all interior and exterior surfaces and parts, including, but not limited to the internal BCD bladder, inside inflator and regulators, and pockets or hard to dry areas of exposure suits, are completely dry.
Determining Factors: Restrictions for Passage Island and the Shipwreck America are necessary to ensure safe and unrestricted access for concession vessels that provide scheduled visitor transportation services in these areas. Shipwreck mooring buoys are established solely to secure vessels actively diving or in the process of diving on the shipwreck sites and to protect historic resources. The purpose of the decontamination requirements is to protect park resources and prevent the introduction and spread of Aquatic Invasive Species such as Zebra Mussels and diseases such as VHSv.
Firewood
Transportation, importation, and/or possession of firewood obtained from sources outside of Isle Royale National Park are prohibited.
Determining Factors: This restriction is necessary to prevent the spread of invasive insect species such as Emerald Ash Borer to Isle Royale.
Unmanned Aircraft
Launching, landing, or operating an unmanned aircraft from or on lands and waters administered by the NPS within park boundaries is prohibited except as approved in writing through the Superintendent's Office. See unmanned aircraft definition above.
Determining Factors: Until the NPS determines whether specific uses of unmanned aircraft are appropriate and will not cause unacceptable impacts on park resources and values, Isle Royale National Park is closed to the use of these devices. The use of unmanned aircraft within the boundaries of the park has the potential to harm visitors, disturb wildlife, impact viewsheds, cause excessive noise, and interfere with other visitors' enjoyment of the area and may be incompatible with the purposes for which the park was established, including providing those opportunities for recreational, use and experiences which are compatible with the preservation of the park’s wilderness character. A less restrictive approach is not appropriate due to the impacts the devices could potentially present to visitor safety, park values, and park resources. Per 36 CFR §1.5(a)(2), the following areas have been designated for a special use or activity, under the conditions and/or restrictions as noted:
36 CFR §1.5(a)(2), the following areas have been designated for a special use or activity, under the conditions and/or restrictions as noted
Compressors
The use or operation of a portable or permanently installed on-board compressor to fill SCUBA diving tanks is prohibited at all locations within the park except:
While underway in the Lake Superior Open Water Motorized Zone.
When moored at a shipwreck mooring buoy, between 6 a.m. to 10 p.m. EDT.
At the Washington Harbor and Snug Harbor public docks between 8 a.m. to 12 p.m. (noon) and 3:30 p.m. to 5 p.m. EDT.
The far west end of Florence Bay, Glenfiddick Bay (west and north of Duncan Bay), and the unnamed southwestern arm of Five Finger Bay (lying between Stockly Bay and Duncan Bay), between 8 a.m. to 5 p.m. EDT.
Determining Factor: A compressor used to fill SCUBA diving tanks produces significant noise and potential disturbance to park visitors. These actions protect the natural quiet and wilderness values sought by most Isle Royale visitors. A specific provision in the GMP allows the operation of a compressor within some locations not near any park campgrounds or trails. The Superintendent has determined that the occasional use of an on-board compressor at these locations is not likely to disturb other visitors.
Quiet and No Wake Zones
The following Quiet/No Wake Zones are designated within the boundaries of Isle Royale National Park:
Barnum/Washington Islands: the sheltered waters bordered on the North by Barnum Island, on the west and south by Washington Island, and on the east by Booth Island.
All of Chippewa Harbor: beginning at the small, unnamed island of rock located at the narrow entrance to the harbor.
All of Conglomerate Bay.
Crystal Cove: all of Crystal Cove on the northeast end of Amygdaloid Island.
Hay Bay: beginning at a point 1/8-mile northeast of the Hay Bay Campground and dock, thence southwesterly to the end of the bay.
All of Duncan Bay, including side bays, beginning at the Duncan Bay Narrows.
Five Finger Bay (including Stockly Bay): all waters within these two bays located south of a line running from Hill Point, thence northeasterly on a straight line through Battleship Island to the main island of Isle Royale.
Johns Island: the entire small cove located on the northeast side of the island.
All of Lane Cove.
Lorelei Lane: the narrow waterway beginning at the northeast end of Mott Island, thence northeasterly to Smithwick Channel. This designated zone is bordered on the south by a line of named and unnamed islands including (from southwest to northeast) Outer Hill, Mad, and Heron islands. The zone is bordered on the north by Inner Hill, Star, Davidson, Tookers, Shaw, and Smithwick islands.
Malone Bay: that portion of Malone Bay bordered on the east and south by Hat, Ross, and Malone islands, thence northwesterly to the point of land adjacent to the Malone Bay dock, thence northeasterly along the shoreline to Hat Island.
All of McCargoe Cove (including Brady Cove) beginning at the mouth (Indian Point).
All of Merritt Lane: beginning at Red Rock Point near the southwest end of Porter Island, thence northeasterly to a point 1/8-mile northeast of the Merritt Lane Campground dock, and including all waters bounded by Porter Island on the west, Long Island, and Third islands on the south, and Elizabeth and Merritt islands on the east.
All of Moskey Basin beginning at Baker Point.
Passage Island: all of the Small Boat Cove on the south side of Passage Island.
Robinson Bay, Pickerel Cove, and Belle Harbor Area: all of the named waters. The coastline of Belle Isle (south shore) and the main island (Isle Royale) define the north, west, and south perimeters of the zone. The eastern perimeter begins at the northeast end of Belle Isle, thence southeast to the southwest end of Cork Island, thence northeasterly to the southwest end of Dean Island, thence northeast along the south shore of Dean Island to the northeast end of the island, and on a direct line to Hill Point.
Tobin Harbor: the western half of Tobin Harbor, beginning at a line connecting Moose Point on the south and the Duncan Bay Portage Trail on the north, thence southwesterly to the west end of the harbor.
Todd Harbor: beginning at Kamloops Point, thence following the coastline southwesterly around the perimeter of the harbor to Wilson Point, thence northeasterly on a direct line back to Kamloops Point.
Wright Island: the sheltered cove adjacent to the historic Wright Island Fishery located on the southwest side of Wright Island.
Determining Factors: Zones established in the GMP protect the natural quiet and wilderness values sought by most park visitors and reduce wake impacts on park resources and paddlers. The zones promote a quality visitor experience by providing relatively tranquil, natural marine surroundings and are in sheltered harbors and bays where calm water and relative quiet are desirable for resource protection.
No Wake Zones
The following No Wake Zones are designated within the boundaries of Isle Royale National Park:
Mott Island:within theRock Harbor Channel, between the buoys placed north of Mott Island on the eastern and western edges of the park administrative and housing areas.
Snug Harbor (Rock Harbor Marina):within the marked harbor and marina area.
Washington Harbor:within the harbor area marked by buoys.
Determining Factors: No wake zones are designated in high traffic and developed areas to improve visitor safety by reducing vessel speeds and the risk of collision, reducing the risk of collisions, and reducing the risk of damage or injury caused by a wake pushing a vessel into or onto a dock.
Discharge of Ballast Water
The discharge of any untreated ballast water that comes from outside of park waters is prohibited within the boundaries of Isle Royale National Park. Park boundaries include those waters within the territorial jurisdiction of the United States within 4.5 miles of the shore of Isle Royale and immediately surrounding islands, including Passage Island, Gull Islands, and international boundary. Untreated ballast water is defined as ballast water that is not treated by one or more of the State of Michigan Department of Environmental Quality treatment methods. The following ballast water treatment methods are acceptable: 1) hypochlorite treatment; 2) deoxygenation treatment, 3) chlorine dioxide treatment; and 4) ultra-violet light radiation treatment preceded by suspended solids removal. Requirements for each of these treatment techniques can be found within the State of Michigan Department of Environment, Great Lakes, and Energy, Ballast Water Control General Permit, Port Operations and Ballast Water discharge, Permit No. M0G140000.
Determining Factors: The purpose of this restriction is to prevent the introduction and spread of Aquatic Invasive Species and disease including Viral Hemorrhagic Septicemia Virus. There have been detections of VHSv in far eastern Lake Superior as well as Duluth Harbor and other locations of western Lake Superior. The Lake Superior waters of Isle Royale hold diverse populations of multiple species of fish including lake trout, coaster brook trout and lake whitefish which are all susceptible to VHSv and are known to be present in Lake Superior. These species contribute substantially to recreational fisheries at the park. Migratory species, such as lake trout, also contribute to both commercial and recreational fisheries outside of park waters.
Service Dogs
The Americans with Disability Act (ADA) definition and guidelines for service dogs are followed at Isle Royale. However, to protect wildlife on the island from transmission of disease or parasites, service dogs must have an approved veterinary certificate dated no more than 15 days before they are brought within Isle Royale National Park boundaries. Contact the Houghton Visitor Center or visit https://www.nps.gov/isro/planyourvisit/service-dogs.htm to download the required Service Dog Veterinary Certification Form.
Handlers are required to bag and dispose of feces from service dogs in garbage receptacles.
Service dogs must be harnessed, leashed, or tethered, unless these devices interfere with the service animal’s work or the individual’s disability prevents using these devices. In that case, the individual must maintain control of the animal through voice, signal, or other effective controls.
If a service dog becomes ill while on the island, then the handler and service dog must leave the park to prevent the spread of illness to wildlife.
Determining Factors: Service dogs are authorized under the ADA, however, the NPS must protect the unique and isolated archipelago ecosystem. Therefore, service dogs are required to receive a veterinary check certifying they are healthy prior to entering park boundaries. The park witnessed devastating effects of disease on wildlife populations in the past. Canine parvovirus (CPV2) was transmitted to the island and infected the wolf population, and the disease along with intraspecific mortalities, and decreasing prey abundance led to a population decline from 50 individuals to 14. Fox and American marten on Isle Royale are also susceptible to canine parvovirus. 36 CFR §7.38(c) currently states “Dogs, cats, and other mammals may not be brought into or possessed in the park area, except for guide dogs accompanying the blind.”
CCTV Policy Statement
Closed circuit television systems (CCTVs) are in use at Isle Royale National Park within and around federal buildings to provide for the protection of employees and property. In accordance with NPS Law Enforcement Reference Manual 9 (RM-9), notice is hereby given that Isle Royale National Park uses CCTV security camera monitoring.
The park’s use of CCTV for law enforcement and security purposes will only be to visually monitor public park areas and public activities where no constitutionally protected reasonable expectation of privacy exists. Such use, which will have adequate privacy and First Amendment safeguards, will be to help ensure public safety and security; facilitate the detection, investigation, prevention, and deterrence of terrorist attack and crime; help ensure the safety of citizens and officers; help assist in the proper allocation and deployment of law enforcement and public safety resources; and help facilitate the protection of the innocent and the apprehension and prosecution of criminals (RM-9, 26.1).
This policy does not restrict the official use of CCTV in government administrative areas, including administrative buildings (RM-9, 26.3.7) where the government may record/monitor its facilities. For example, the government may perform unrestricted video/audio recording at revenue collection points (entrance stations, visitor center counters, etc.). This policy does not restrict the use of an Audio/Visual Recording Device (AVRD) in patrol vehicles or officer-worn recording devices used by commissioned rangers (RM-9, 26.1).
Operation of CCTV cameras, maintenance of recorded images and use of recorded images will be in accordance with NPS and Department of Interior policy and applicable laws and regulations (RM-9, 26.1-26.4). No person will be targeted or monitored merely because of race, religion, gender, sex, disability, national origin, or political affiliation or views (RM-9, 26.4.2).
Wildlife
To protect park wildlife, the following are prohibited:
Knowingly approaching, remaining, viewing, or engaging in any activity:
Within 25 yards of any wildlife.
Within any distance that disturbs, displaces, or interferes with the free unimpeded movement of any wildlife.
Within any distance that creates or contributes to a potentially hazardous condition or situation.
Failing to remove oneself to prescribed distances during inadvertent, accidental, or surprise encounters with wildlife.
The prohibitions of this section do not apply to someone who is:
In compliance with written protocols approved by the Superintendent.
In accordance with the terms and conditions of a permit issued by the Superintendent.
Determination: The Superintendent has determined that these public use restrictions and requirements are necessary to maximize public safety, protect wildlife, and provide park staff with the flexibility to situationally manage dynamic, diverse, and rapidly evolving wildlife viewing opportunities.

36 CFR Part 2 – PRESERVATION OF NATURAL, CULTURAL, AND ARCHEOLOGICAL RESOURCES
36 CFR §2.1 – PRESERVATION OF NATURAL, CULTURAL, AND ARCHEOLOGICAL RESOURCES
(a)(4) Dead wood on the ground and driftwood may be collected for use as fuel for campfires within the park in the following areas:
In areas with park-provided fire rings or grills (see Section 2.13).
Near campgrounds when using a self-contained wood-burning backpacking stove.
Driftwood along Isle Royale’s Lake Superior shoreline.
Determining Factor: Limited use of this wood will not adversely affect park resources.
(c)(1) and (c)(2) The following fruits, nuts, or berries may be gathered by hand for personal use or consumption, only in accordance with the noted size, quantity, collection sites and/or use or consumption restrictions:
Apples
Beach peas
Blueberries
Chokecherries

Wintergreen berries
Listed fruits, nuts, and berries may be gathered in quantities not to exceed one quart per person per day; except for apples which may be gathered in quantities not to exceed two gallons per person per day; and blueberries, raspberries, thimbleberries, and mushrooms which may be gathered in quantities not to exceed four quarts per person per day.
Determining Factor: This use provides the broadest use and enjoyment of the park in the least restrictive manner so long as there is no adverse effect to park wildlife, the reproductive potential of a plant species or otherwise adverse effect of park resources.
36 CFR §2.2 - WILDLIFE PROTECTION
(d) The transporting of lawfully taken wildlife through the park is allowed under the following conditions and procedures:
Transporting wildlife through Isle Royale National Park is prohibited.
Determining Factor: Isle Royale is an island closed to the legal taking of wildlife and there are no roads passing through the park that would necessitate access through the park.
(e) The following areas are closed to the viewing of wildlife with the use of an artificial light:
The use of an artificial light to view wildlife anywhere in the park is prohibited.
Determining Factor: This restriction is necessary for the protection of wildlife from unnecessary stress. Artificial light can alter natural habits including mating, resting, and feeding. Artificial light also disrupts the natural darkness of night sky that visitors enjoy and expect in wilderness.
36 CFR §2.3 – FISHING
See additional fishing section above, 36 CFR §1.5 (a)(1).
(d)(2) Possession or use of live or dead minnows or other bait fish, amphibian, non-preserved fish eggs, or roe is allowed in the following freshwater areas:
All Isle Royale inland waters are closed to the use of all live or dead bait.
Determining Factors: The use of fish, fish parts, roe (fish eggs), amphibians, insects, invertebrates (leeches, worms, and clams) for recreational bait fishing is a means by which Aquatic Invasive Species and diseases detrimental to fish populations can be transmitted to inland waters. These bait restrictions apply to all inland lakes, streams, and rivers of Isle Royale to protect the fish from disease transmission.
(d)(8) Fishing is allowed in or from the following otherwise prohibited areas: Public boat docks:
Fishing is allowed from all public boat docks, so long as it does not interfere with boat traffic.
Determining Factor: This restriction is necessary for the safety of those fishing on the dock and boaters approaching and/or docking.
36 CFR §2.10 – CAMPING and FOOD STORAGE
(a) The sites and areas listed below have been designated for camping activities as noted. A permit system has been established for certain campgrounds or camping activities, and conditions for camping and camping activities are in effect as noted:
Permit required for all overnight stays within the park, except Rock Harbor Lodge guests, and guests of employees and/or authorized residents staying at their assigned quarters, dock, or guest housing.
Small parties are defined as parties consisting of 1-6 persons.
Group campsites are typically for parties from seven persons to no more than 10 persons.
The following areas are closed to camping:
Within ½ mile of all eagle and osprey nests.
Passage Island.
Within ¼ mile of any trail or portage.
Within ½ mile from all developed areas, designated campgrounds, and fire towers.
All offshore and inland lake islands except those officially designated with campsites.
There are 46 Backcountry Camping Zones. A map and information on restrictions and closures for each zone can be found at park visitors centers and on the park website.
The west end of the Island between Todd Harbor to the north and Fisherman's Home to the south is closed to commercial kayak trips.
Determining Factor: This action implements components of the GMP to prevent establishment of undesignated campsites by repeated use in sensitive resource areas. This action helps maintain isolated shorelines with outstanding opportunities for solitude. Backcountry Camping Zones and/or allowable uses are monitored and revised to protect park resources.
The following docks are closed to camping and overnight docking/mooring. Docking/mooring is prohibited between the hours of 10 p.m. EDT and 6 a.m. EDT:
Amygdaloid Island Dock (exceptfor residents or invited guests of residents).
Crystal Cove.
Edisen Fishery Dock (except for residents or invited guests of residents).
Hidden Lake Dock.
Malone Bay Dock, north side (except for residents or invited guests of residents).
Mott Island Docks (except for residents or invited guests of residents).
Passage Island Docks.
Ranger III Dock at Rock Harbor.
Raspberry Island Dock.
Any fuel dispensing dock except the south side of Malone Bay dock.
Any dock posted or signed as closed to overnight use or public entry.
All docks assigned to park volunteers and special use permittees, except by permission of permittee.
All shipwreck mooring buoys are closed to camping and overnight use.
At docks where overnight use is permitted:
Dock space is available on a first-come, first-served basis.
Docks and shelters may not be reserved or held for others.
Boaters already set up at a campsite or shelter and who have a valid camping permit shall be given priority access to space at the dock.
Determining Factor: Docks located at Raspberry Island, Edisen Fishery, Passage Island, and Hidden Lake are in areas designated for day use only and do not have necessary facilities for overnight use. Closure of the docks to overnight use provides ready access to the docks for transient vessels whose occupants desire to day hike or visit interpretive exhibits at these locations. Further, the closures help protect sensitive natural and/or cultural resources at these locations. The north side of the Malone Bay dock, the Ranger III dock at Snug Harbor, the NPS and concession fuel docks, and the docks at Amygdaloid and Mott Islands are closed to provide for the docking needs of vessels used for park administrative and emergency purposes. Shipwreck mooring buoys are established solely to secure vessels actively diving or in the process of diving on the shipwreck sites and to protect historic resources.
Camping outside of the following conditions is prohibited:
A party may only use or occupy one site at each campground.
A party may not split up or register separately obtaining two permits for the purpose of obtaining two sites.
Shelters may not be used for the sole purpose of storage and/or cooking. Temporary additions to shelters such as food storage boxes, lean-tos, clothes drying racks, lining with plastic, when attached with nails, staples, tape, and/or tacks, are prohibited.
Tents may not be erected outside of tent pads where provided.
Hammocks may not be attached to the interior or exterior of shelters.
Group camping (parties of 7-10 people):
Groups must have camping reservations before arriving on the island.
10 persons is the maximum size of any camping party.
No organization/entity may have more than 20 persons camping within the boundaries of Isle Royale National Park at any one time.
No organization/entity may exceed 80 persons per year camping within the boundaries of Isle Royale National Park.
Groups of more than 7 people must use established group campsites.
Groups of more than 7 people may not use shelters or campsites other than designated group sites or engage in cross-country overnight travel.
Groups must not deviate from itineraries listed on backcountry permits, except when changed by an authorized NPS representative or due to an emergency. Small parties (six persons or less) that are associated with other parties from the same group/organization that are camping on the island during the same time period must apply for their permits in advance. For example, if you are organizing two small parties of six persons from your church to go canoeing at Isle Royale, you must apply for your permit in advance.
Small parties (six persons or less) associated with other parties from the same group/organization may not change their permits or itineraries in a way that cause two or more parties from the same group/organization to camp in the same campground on the same night. For example, your summer camp has scheduled and applied for permits in advance, for three small parties of six backpackers each to Isle Royale. During their trips, the parties may not change their itineraries in such a way as to end up in the same campground on the same night.
Parties with separate overnight permits, but sharing the same affiliation (camp, school, church, scout group, organization, family, friends, etc. or any combination thereof) may not camp within one half (0.5) mile of each other.
Cross-Country Travel/Camping:
Only parties of 1-6 individuals are allowed to camp in cross-country areas.
A cross-country permit is required for camping outside of developed campsites.
The camp must be out of sight and sound of other camping parties.
Maximum stay at any location is one night.
Must camp at least ½ mile from the previous night’s stay (tent and camping gear must be moved).
Must be at least ¼ mile away from any trail or portage and at least ½ mile from all developed areas, designated campgrounds, and fire towers.
At most campgrounds, camping longer than stay limitations at designated campgrounds and their associated docks between June 1 and September 2 is prohibited unless specifically authorized by permit. At Rock Harbor, Lane Cove, Three Mile and Washington Creek campgrounds, stay limits apply until September 21.

(b)(3) Camping within 25 feet of a fire hydrant or main road, or within 100 feet of a flowing stream, river or body of water is authorized only at designated campsites. (d) Conditions for the storage of food are in effect for the entire park with the following requirements:
Boaters
All food, lawfully taken fish, garbage, grills, cooking supplies and utensils, and scented items (such as toothpaste, sunscreen, lip balm, etc.) shall be kept secured in a boat, ice chest, camping structure, or other container constructed of a solid, non-pliable material, and with a secure lid to prevent access by animals.
Backpackers/Day Hikers
All food, garbage, and scented items (shoes, socks, cookware) shall be securely stored and monitored/attended to prevent access by animals. Storage of these items in tents and unattended packs is not permitted. Campsite shelters are an approved location to secure all items. For campers not in a shelter, large, gated lockers (kennels or bear barrels/boxes) are available near tent and group sites at Lane Cove, Rock Harbor, Three Mile, Daisy Farm, and Moskey Basin campgrounds. As an alternative to scent-proof bags or containers, visitors may hang their food/trash/scented items in a tree at height greater than 10 feet, and tent campers may ask to temporarily store their food/trash/scented items in a shelter in-use by others.
Determining Factor: The intent of these designations is to protect wildlife and park visitors by preventing squirrels, mice, foxes, birds, wolves, and other wildlife from obtaining and habituating to food and garbage and/or damaging equipment and property. Additional restrictions and clarifications were added summer 2024 in response to animals accessing food and trash while the park conducts wildlife management and public education and determines best practices for the 2025 field season.
36 CFR §2.13 – FIRES
(a)(1) The lighting or maintaining of fires is prohibited, except as provided for in the following designated areas and/or receptacles, and under the conditions noted:
Fires are authorized in designated community fire rings in these locations:
Caribou Island
McCargoe Cove
Siskiwit Bay
Todd Harbor
Fires are authorized in park-provided fire rings or standing grills in these locations:
Belle Isle
Chippewa Harbor
Duncan Bay
Duncan Narrows
Island Mine
Little Todd
Malone Bay
Rock Harbor Marina
Employee Housing (includes administrative sites, such as Washington Island, Tobin Harbor cabins and similar)
Commercially manufactured charcoal or propane barbeque grills may be used in these locations:
Non-wilderness campgrounds
Personal boats
Employee housing
Remaining charcoal or charcoal ash must be completely extinguished and disposed of in designated trash receptacles or hauled off-island.
All propane containers/canisters must be hauled off island, or returned to the island stores for reuse or disposal.
(a)(2) The following restrictions are in effect for the use of stoves or lanterns:
Lighting or maintaining a fuel-burning stove or lantern within 50 feet of a fuel-storage tank or dispensing facility is prohibited.
Small self-contained personal backpacking fuel and twig wood-burning stoves are allowed. Self-contained twig wood-burning stoves hold the fire and embers within a small fire box (approximately 7” or less) and leave little ash. The fire box prevents fire spread and the scorching of soil.
(b) Fires must be extinguished with water and stirred until cool to the touch, with no residual hot embers.
Determining Factors: These fire restrictions are necessary to protect natural and cultural resources, infrastructure, and public safety. *The park plans to remove Island Mine fire ring/s at the end of the 2024 season and update the Compendium accordingly in 2025. Monitoring indicates that area has limited dead and down wood, contains sensitive resources, and does not reliably have adequate access to water for extinguishing a campfire.
36 CFR §2.14 – SANITATION and REFUSE
(a)(7) Conditions for the disposal of fish remains near docks or within developed areas have been designated as follows:
Cleaning of fish directly on docks or picnic tables is prohibited.
Developed and Undeveloped Areas, Lake Superior Waters
Disposing of fish remains in developed areas is prohibited except by puncturing the air bladder and disposing of them in Lake Superior water greater than 50 feet deep with flow-through circulation. Shore anglers without access to a boat may dispose of fish remains by cutting them into pieces 4 inches or less, puncturing the air bladder, moving at least 200 feet along the shoreline away from the campground, dock, or other developed area, and throwing remains as far as possible, aiming for deepest water. In Windigo/Ozaagaateng, shore anglers without access to a boat may dispose of fish remains off the end of the main dock.
Undeveloped Areas, Inland Lakes
Disposing of fish remains on inland waters is prohibited except by cutting the remains into pieces 4 inches or less, puncturing the air bladder, and disposing of them into deep water via canoe/kayak, or by cutting the remains into pieces 4 inches or less, puncturing the air bladder, moving at least 200 feet along the shoreline away from the campground or campsite, and throwing remains as far as possible, aiming for deepest water.
Determining Factor: The intent of these designations is to prevent wildlife from obtaining and habituating to fish remains provided by visitors and for public health and safety.
(a)(9), (b) Conditions for the disposal, containerization, or carryout of human body waste have been established as follows:
Disposing of human waste in established backcountry campgrounds other than in designated privies is prohibited.
In backcountry areas where privies are not available, disposing of human waste is prohibited except by removal from the island with appropriately bagged waste or by burial in a hole 6 inches deep, covered with soil, out of site from a trail, and least 100 feet from any water source, high water mark of any body of water, or campsite.
All toilet paper shall be packed out, except toilet paper disposed of in a designated privy or toilet.
Determining Factor: These requirements are intended to ensure that proper disposal/removal of human waste occurs in the backcountry to protect water quality, visitor safety, and natural resources.
36 CFR §2.15 – PETS
(a)(1) The Park is closed to dogs, cats, and other mammals. This does not include service dogs, although, as described above, service dogs require a permit.
See 36 CFR §1.5(a)(2) and 36 CFR §7.38(c).
(e) Some pets may be kept by park residents under the following conditions:
Park residents may keep pets other than mammals in their residence consistent with the Isle Royale National Park Housing Management Plan and with approval by the park Superintendent. Species of concern include, but are not limited to goldfish, amphibians, turtles, and some bird species.
See 36 CFR §1.5(a)(2) and 36 CFR §7.38(c).
Determining Factors: This restriction protects park wildlife and the unique and isolated island archipelago ecosystem.
36 CFR §2.17 – AIRCRAFT and AIR DELIVERY
(a)(1) Areas designated for operating or using aircraft are provided for in 36 CFR §7.38.
(a)(2) Boat docks or piers designated as open for the use of seaplanes. All docks and piers are closed to non-administrative seaplane use except the following, subject to other park rules and regulations:
Washington Harbor concession boat dock.
Washington Harbor seaplane dock, open for fifteen-minute loading and unloading only from 8:00 a.m. to 7:00 p.m. EDT daily. Open for overnight use at other times.
Tobin Harbor, eastern most NPS dock.
Tobin Harbor seaplane dock, open for fifteen-minute loading and unloading only from 8:00 a.m. to 7:00 p.m. EDT daily. Open for overnight use at other times.
Mott Island seaplane dock, open from 8:00am to 5:00pm only, with a two-hour maximum stay. Contact the Houghton Visitor Center to see if the dock is available prior to traveling to the island.
Determining Factors: Seaplane dock access is designated in specific areas and times to ensure safe and unrestricted access for concession aircraft that provide scheduled visitor transportation services and NPS aircraft used in research and emergency services.
(c)(1) The removal of a downed aircraft, components, or parts thereof are subject to procedures established by the Superintendent through written authorization.
36 CFR §2.20 – SKATING, SKATEBOARDS and SIMILAR DEVICES
Like limited allowances for the use of bicycles, the use of roller skates, skateboards, roller skis, coasting vehicles, or similar wheeled devices are allowed only in the following areas:
Using roller skates, skateboards, roller skis, coasting vehicles, or similar wheeled devices is prohibited except for park residents in the developed and paved areas of Mott Island and Rock Harbor during periods when normal park operations, including ferry boat operations, are neither in process or scheduled. This use must not interfere with visitor activities such as a safe walking path, must not interfere with any park operations, and must not occur during quiet hours (10 p.m. to 6 a.m.).
Determining Factor: The paved areas of Mott Island and Rock Harbor are working docks and areas where administrative motor vehicles operate. Limited after business hours access allows residents living on the island an opportunity to use these devices as a limited exercise and recreational opportunity without interfering with park operations. Other developed areas do not have pavement for these devices to operate.
36 CFR §2.21 – SMOKING
(a) The following portions of the park, or all or portions of buildings, structures, or facilities are closed to smoking as noted:
All public buildings, including concession buildings;
All government-owned and operated facilities, vessels, and vehicles except certain marked designated smoking areas on the M.V. Ranger III, and the M.V. Angelique.
Prohibited within 100 feet of fuel and propane tanks; and
Park residents must follow the Smoking Policy in the Housing Management Plan.
Determining Factor: These restrictions are intended to protect public health and public safety from fire or explosion around fuel storage facilities. Electronic cigarettes are included in the above restrictions. When needed, temporary closures for high wildfire danger or other health and safety reasons will be posted on the park website: https://www.nps.gov/isro/planyourvisit/current-conditions-at-isle-royale.htm.
36 CFR §2.22 – PROPERTY
(a)(2) Property may be left unattended for periods longer than 24 hours only in the following areas and under the following conditions:
Long-term parking areas in Houghton, MI when staging for or traveling to/from the park.
At concession facilities with prior arrangements made with concessionaire.
Any area with written permission from the park Superintendent.
Determining Factor: The superintendent has established the allowance for parked vehicles in designated long-term parking areas on the mainland (Houghton, MI) so that these approved vehicles are not considered abandoned property or impounded.
36 CFR §2.23 – RECREATION FEES
(b) Recreation fees, and/or a permit, in accordance with 36 CFR part 71, are established for the entrance fee area (Isle Royale National Park), and/or for the use of the following specialized sites, facilities, equipment or services, or for participation in the following group activity, recreation events or specialized recreation uses:
Daily Entrance Fee
$7.00 per person per day. Children 15 and under are exempt from the fee.
Isle Royale Season Pass
$60.00 This optional pass is valid from April 16 through October 31 of the year indicated. The pass covers the Entrance Fee for the person whose signature appears on the pass plus three accompanying adults and is used instead of payment for separate daily entrance fees.
36 CFR §2.35 – ALCOHOLIC BEVERAGES and CONTROLLED SUBSTANCES
(a)(3)(i) The following public use areas, portions of public use areas, and/or public facilities within the park are closed to consumption of alcoholic beverages, and/or to the possession of a bottle, can or other receptacle containing an alcoholic beverage that is open, or has been opened, or whose seal has been broken or the contents of which have been partially removed:
Within visitor centers, the breezeway between the Rock Harbor Visitor Center and Dockside Store, the deck of the Windigo/Ozaagaateng Visitor Center, and, unless authorized, on board the park vessel Ranger III. In accordance with the park employee handbook, employees authorized to utilize the vessel Ranger III as quarters are allowed to consume or possess alcoholic beverages aboard the Ranger III when off-duty.
Determining Factor: The superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.
36 CFR §2.38 – EXPLOSIVES
(b) Fireworks and firecrackers may be possessed and/or used in the following areas, under the conditions noted:
Using or possessing fireworks and firecrackers (including sparklers) is prohibited in all land and water areas of the park.
Determining Factor: The superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection, including protection of wildlife.
36 CFR §2.51 – PUBLIC ASSEMBLIES, MEETINGS
(e) The Superintendent shall designate on a map the locations available for public assemblies:
Public assemblies or meetings are permitted only in the areas designated at Houghton, Rock Harbor, and Windigo/Ozaagaateng. See First Amendment Area Maps on the park website. Copies are also available in park visitor centers.
Demonstrations must not block ingress or egress to buildings, docks, or roadways.
Demonstrations involving 26 or more individuals must have a permit issued by the Superintendent.
Determining Factor: The superintendent has established locations for the public to safely gather while exercising their first amendment rights, reduce conflicts between groups, ensure park operations can safely continue, and ensure park visitors are free from harassment.
36 CFR §2.62 – MEMORIALIZATION
(b) The scattering of ashes from cremated human remains.
A permit is required to scatter cremated human remains. Contact e-mail us for more information.
Determining Factor: This restriction is necessary for public safety and resource protection, including protection of culturally sensitive locations.
36 CFR §3.8 – BOATING OPERATIONS
(b)(3) Operating a vessel in excess of flat wake speed in the following areas is prohibited:
In all water areas surrounding any beached boat or canoe within 300 feet.
Determining Factor: In the interest of public safety, areas may be designated for flat wake speed. In the occasional circumstance that a vessel is beached restricting vessels in waters within 300’ will help to minimize damage to the beached vessel and be less likely to upset the balance of a person boarding or exiting a beached vessel.
36 CFR §3.12 – WATER SKIING and TOWING of AIRBORNE DEVICES
(a) The towing of persons using water skis, or similar devices, is prohibited within the waters of Isle Royale National Park.
(b) The towing of a person using a parasail, hang-glider or other airborne device is prohibited within the waters of Isle Royale National Park.
Determining Factor: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety, resource protection, and for consistency with the Wilderness Act. These restrictions are necessary to eliminate large wakes that may damage or capsize non-motorized vessels, reduce risk of impact of motorized vessels with other vessels or marine hazards such as reefs, and eliminate collision risk with aircraft operating around the park and landing in park waters.
36 CFR §4.30 – BICYCLES
Areas open for bicycle use under 36 CFR 4.30(a) are the NPS owned parking areas in Houghton, MI. Bicycle racks are available near the Washington Harbor and Rock Harbor docks for visitors needing temporary storage of a bicycle while on-island. There are no areas on-island open to bicycle use by the public.
(b) Administrative roads are open for employee/resident use of bicycles and electric bicycles when such use will not adversely affect park visitors or operations. These roads are in the developed areas of Rock Harbor, Mott Island and Windigo/Ozaagaateng.
Determining Factor: On September 28, 2021, using discretionary authority, the Superintendent authorized these administrative roads as open to bicycles under 36 CFR 4.30(b) and electric bicycles under 36 CFR 4.30(i). Allowing bicycles and electric bicycles on these administrative roads creates opportunity, especially for employees and their children, and is not expected to create adverse impacts to park visitors, resources, or values due to the existing administrative use of motor vehicles on these roads. This action is covered by a categorical exclusion, 3.3.D.2.
