Safety for 2024

  • Your safety is your responsibility. Have a conservative trip plan, plan your gear with conditions in mind, be first aid ready, and have plans on what you might do in case something goes wrong. Self-rescue is the best rescue as park response is limited and help could be hours or days away. Come prepared with everything you may need.
  • Water is Life: Stay Hydrated. Potable water is only available in Rock Harbor and Windigo. To be assured of no risk of contamination from small bacteria and viruses, all filtered water should be further treated with iodine or other approved chemical methods.

  • Downed Trees: Obstructions do exist on trails and in campgrounds. Bring hiking poles to assist with difficult sections and wear sturdy, well-broken-in footwear.
  • Trail Navigation: Changing trail conditions due to beaver activity and wildfires from previous years can make certain sections of trail difficult to navigate. Have a map and compass and/or a GPS and know how to use them.

Water Conditions

  • Swimmer's Itch Present in Park Waters
  • Harmful Algal Blooms: There are no algal blooms reported in the park. Any suspected algal blooms should be reported to a park visitor center.

Wildlife 

  • Moose Rut: Bull moose behavior is unpredictable during the moose rut (mating season). If a bull moose were to approach, protect yourself by putting a large tree or rock between you and the moose.
  • Cow Moose with Calves: Cow moose are extremely protective of their calves. If you see a cow moose (no antlers), look to see if there is a calf around. If a cow moose were to approach, protect yourself by putting a large tree or rock between you and the moose.
  • Wolves: If you see a wolf, do not approach. If the wolf comes closer, encourage it to leave by clapping and yelling. If you cannot safely leave, make yourself big and aggressively use hiking poles or branches. Wolf attacks are extremely rare and unlikely to happen, but if it does, fight by any means necessary.
    • Increased Potential for Wolf/Human Interactions Island-Wide: Wolf/human interactions may occur throughout the park.  The NPS closely monitors wolf/human interactions in order to maximize safe park experiences while minimizing disturbance to wildlife. At campgrounds, keep food and personal items secure inside tent or shelter. Report all sightings and interactions to a park ranger as soon as possible. 
    • Wolf Management in Rock Harbor: There have been repeated wolf encounters in the developed area of Rock Harbor. Wolves have been investigating human food sources, including trash cans and items at campgrounds. To stop this behavior, National Park Service staff are performing actions that encourage wolves to leave the Rock Harbor area. These actions include loudly shouting, stomping, and clapping, and discharging paintball rounds.
    • New Food Storage Guidelines to Reduce Human - Wildlife Interactions: New food storage protocols are in effect for all visitors entering Rock Harbor, Three Mile, Lane Cove, Daisy Farm, Moskey Basin, Duncan Bay, Duncan Bay Narrows, and Merritt Lane Campgrounds.
