Winter Snowshoeing in RMNP
Rocky Mountain National Park maintains year-round access from the Grand Lake west entrance, and the snow-covered west-side trails offer excellent snowshoe routes from November through April. The Colorado River Trail is flat and accessible for all fitness levels when covered in snow — the winter landscape is dramatically different from summer and the wildlife viewing remains excellent.
The East Inlet lower section (to Adams Falls and beyond) is accessible by snowshoe in winter. The East Inlet valley fills with snow that can be 3 to 5 feet deep by February, creating a quiet, pristine winter hiking environment.
Unplowed Park Roads
When park roads are closed to vehicles due to snow — which includes Trail Ridge Road from mid-October through late May — those roads become excellent snowshoe and cross-country ski corridors. No park entry fee is required to walk on unplowed roads. The closed section of Highway 34 inside RMNP beyond the winter closure gate offers miles of flat, groomed snowshoe walking.
Check current road conditions and closures at nps.gov/romo before planning a winter RMNP trip.
Gear and Safety
Snowshoe rentals are available in Grand Lake for those who don't have their own equipment. Poles are strongly recommended for balance and stability in snow. Dress in waterproof layers — snow pants, waterproof boots, and gloves are essential in winter conditions at 8,000 to 9,000 feet.
Always let someone know your intended route and expected return time. Winter conditions can change quickly at elevation. Carry a map, emergency shelter, and extra warm layers in your pack.
Winter Access on the West Side
In winter the park's west-side trailheads remain reachable while the high country closes, which is what makes snowshoeing here practical rather than expeditionary. Trail Ridge Road shuts for the season, so winter walking happens in the valley and the lower forest rather than above treeline.
The valley floor routes that are easy summer walks become the natural snowshoe objectives, with the Kawuneeche Valley and the meadow trails carrying most of the traffic.
What Changes in Winter
Distances mean less in snow than on dry trail — a route that takes an hour in July can take twice that after fresh snowfall. Plan by time and conditions rather than by mileage, and turn round on the clock rather than at a landmark.
Daylight is the other constraint. Short days at this latitude and elevation leave a narrower window than groups expect, and the temperature drops sharply once the sun is off the valley.
Gear, Rentals and the Drive
Snowshoes can be rented in Grand Lake, which is simpler than travelling with them for most visitors. Conditions and closures change constantly through the winter — check with the National Park Service before setting out rather than assuming a trailhead is open.
Getting to Grand Lake at all in winter means US-40 over Berthoud Pass, which is maintained but does close for storms and avalanche control. Check cotrip.org before travelling, and every cabin has a hot tub for afterwards.
