Hiking in the Rocky Mountain National Park
10 trails in this Colorado region — with elevation, distance, and seasonal recommendations.
Emerald Lake Trail
A stunning alpine lake hike that passes Nymph Lake and Dream Lake before reaching the spectacular Emerald Lake. Perfect introduction to Rocky Mountain National Park's high country.
Chasm Lake
A challenging hike to a pristine alpine lake beneath the dramatic east face of Longs Peak. The lake sits in a spectacular cirque surrounded by towering granite walls.
Bear Lake Trail
An accessible paved loop around one of Rocky Mountain National Park's most popular lakes with stunning mountain reflections and wildlife viewing.
Lily Lake Trail
A flat, accessible boardwalk loop around a scenic lake with views of Longs Peak and the Continental Divide. Perfect for all abilities.
Sprague Lake Trail
A wheelchair-accessible trail to a pristine alpine lake with stunning reflections of the Continental Divide peaks and Hallett Peak.
Fern Lake Trail
A longer alternative to the crowded Bear Lake corridor. The trail follows the Big Thompson River through Moraine Park, passes The Pool and Fern Falls, and climbs to subalpine Fern Lake. Quieter than Emerald Lake even in peak season.
Cub Lake Trail
An easy hike through Moraine Park's meadows and aspen groves to Cub Lake, a small lily-pad-covered lake surrounded by pines. Wildflowers in July, fall colors mid-September, and one of the most beginner-friendly RMNP trails outside the Bear Lake area.
Bierstadt Lake Trail
Short but steep switchbacks climb to Bierstadt Lake, a quiet forested lake with classic reflection views of Longs Peak and the Continental Divide. The lake is busier in winter for snowshoers than in summer.
Mills Lake Trail
Starts at Glacier Gorge Trailhead and climbs past Alberta Falls into the dramatic Glacier Gorge to Mills Lake, with direct views up to the Keyboard of the Winds and Longs Peak. The trailhead is also the start for Loch Vale and Sky Pond on longer days.
Andrews Glacier Trail
From Glacier Gorge Trailhead, climbs past Loch Vale and up into Andrews Tarn beneath Andrews Glacier — one of the few true glaciers remaining in RMNP. The final stretch is on talus and snow even in midsummer.
