Update - December 4, 2025

Winter has arrived in Rocky Mountain National Park. Following recent storms, all trails in the park are impacted by snow and ice. Conditions can vary greatly based on changes in elevation. At Bear Lake, there are currently 10 inches of fresh snow on the ground.

Use caution around all frozen lakes

It is still early in the season and ice can be thin, especially near inlets and outlets where water is moving under the ice. Walking on frozen lakes or ice skating are not advised.

From now through early June, be prepared for winter hiking conditions; wear warm layers of clothes to help protect your skin from the cold. Waterproof boots, warm socks, traction devices for the bottom of your boots and hiking poles are all recommended for your safety and comfort when recreating in the winter season.

For your comfort and safety, take time to check the weather forecast before beginning your hike. Be prepared for weather and conditions that can change rapidly and be ready to turn back if needed.

Things to Know Before Your Next Hike:

Plan ahead and be prepared for varying weather and conditions. Remember- Your safety is in your hands! Trails inside Rocky Mountain National Park can experience extreme weather and conditions can change quickly. In RMNP, all four seasons can happen in one day!

Any Time of Year - Be prepared: Choose your hiking destination wisely. Know your personal limits and choose a trail that meets your goals within your limits. Be willing to turn back for any reason. Always tell someone where you are going, where you will be parked, what your intended route is, when you plan to be back home, and then let them know when you return.

Lakes: Always proceed with caution around icy lakes, especially around inlets, outlets, and rocks, where the ice can be thin.

Route-finding is important. RMNP trails are not marked in winter and following other tracks is not advised, as you don’t know where they lead, and wind and new snow obliterate tracks. When trails are covered in snow, signs may not be visible. Carry a map and compass or GPS and know how to use them.

Be Prepared for Conditions with Essentials. It is important to bring and use the right gear, especially suitable gear for the season.Plan that trails can be snowy much of the year. Depending on conditions and elevation, some trails can be icy and snowy September through midsummer.

Important questions to consider - Do you have the right gear and equipment for your hike? Do you know how to use it?

• Traction devices for the bottom of your boots and hiking poles are strongly recommended, as trails may be icy. Or depending on conditions after snowstorms or at higher elevations, the snow may be deep enough that snowshoes are advised. Hiking poles are helpful for stability.

• Food and water are essential no matter how long your hike.

• Wear layers of wicking clothing and pack extra socks.

• Bring waterproof outer layers (rain gear/snow gear/windproof jacket) and extra layers for warmth. During the summer season, be prepared for afternoon rain storms.

• Pack a hat and gloves, sunglasses or goggles, and sunscreen any time of year. Sunlight can damage your eyes and skin, even on cloudy days. Protect your eyes from the sun and blowing snow.

• It is advised to wear closed-toed footwear with a treaded sole when hiking. Slick-soled shoes without good traction, sandals, high-heeled shoes, flip flops, and/or clogs can all lead to cold toes, wet feet, and slips, trips and falls.

Roads can be icy and snowy, especially in shady areas. Be prepared and know how to drive in wintery conditions. If the Colorado Vehicle Traction Law is in place in RMNP, for your safety and the safety of other motorists, all vehicles must have properly rated tires with a minimum of 3/16” tread or an approved traction control device.

Pets: Pets are prohibited on all trails, tundra, and meadows areas in Rocky Mountain National Park. For details, see RMNP's Pets Webpage.
