Mills Lake and Black Lake
Packed with snow on both winter & summer trails, very slippery. Past Mills there is soft snow and snowshoes needed to Black Lake.

Glacier Gorge to Blue Lake
Trail snow packed to Mills Lake, only traction devices needed. Ice on Mills and Jewell still solid. Trail from Mills to Black Lake less travelled and snowshoes were used. Continued with snowshoes off trail to Blue Lake.

Pool-Cub Lake Loop
Trail from the winter parking to The Pool is mostly dry and clear. From The Pool to Cub Lake there is snow but it's minimal. From Cub Lake to the Cub Lake Trailhead there is slippery ice and snow, especially up toward Cub Lake. From the Cub Lake Trailhead up the first mile or so the trail is dry. Cub Lake is completely thawed.

Bear Lake to Bierstadt Lake
Trail completely snow covered and packed down. Traction and poles would be recommended. Trail around Bierstadt snow covered. West end of lake appears to be thawing some.

Cub Lake Loop
No snow the first 1 3/4 mile up Cub Lake Trailhead. Icy and snowcovered about a 1/2 mile from Cub Lake. Trail around Cub Lake is dry with a couple snowy places. Trail down from Cub Lake to The Pool mostly snow-covered and icy. Traction definitely needed. Trail from The Pool back to Fern Lake Trailhead is mostly dry with a few muddy spots and a couple very small icy areas.

The Pool to Fern Falls
First 1/4 mile from The Pool is mostly dry trail. Then the trail becomes snow packed and a little icy in places. Fern Falls is completely frozen over. Trail beyond Fern Falls appears to be very snowy. Traction devices needed, but not snowshoes (except if used for traction).

Sprague Lake Trail
Turning right from the trailhead, trail is snow-covered and icy. There is a track through it, but recommend traction devices. The rest of the trail is mostly dry with some icy patches. So about 2/3 dry with icy patches and about 1/3 snow-covered.

Ypsilon Lake from Lawn Lake Trailhead
Trail clear until trail split. Beyond, snow depth was 5 -6 feet deep. snowshoes and poles recommended.

Colorado River Trail
Fresh snow on trail in morning. Snow got deeper after 2 miles.

Bear Lake to Nymph to Dream to Emerald Lakes
Snowpacked and slippery in places. Traction devices and poles definitely desirable. Snowshoes not required unless you go off trail.

Deer Mountain
Patches of snow for the first miles and then all snowpacked and icy to the top of Deer Mountain. Traction devices highly recommended.

Longs Peak Trail
Trail from Longs Peak Trailhead is well-packed snow and lots of bare areas. All boulders at the boulderfield were exposed.

For Your Safety

These Trail Conditions reports are the viewpoints of the submitters, whether park staff, volunteers, or visitors. Conditions can change rapidly in the mountains. Use these reports only as guidelines. Be prepared for varying weather and trail conditions.

Falling trees are ever-present hazards when traveling in the forest. Be aware of your surroundings. Dead trees can fall without warning!

Due to the September 2013 Flood, missing foot bridges, uneven trail surfaces, unstable slopes, falling trees due to soil moisture, rutted trails, damaged water bars and steps, standing water, difficult water crossings, and missing directional signs could be encountered. Most of Rocky Mountain National Park is designated wilderness, where self-reliance and adventure are expected. Hikers should be prepared to take responsibility for their own actions; search and rescue may be delayed. Be prepared to stay overnight even if you are a day hiker. Hiking poles may be helpful on uneven trails. Route finding skills may be required. Carry a map and compass and other backcountry travel essentials. Hike at your own risk.
