Trail shared by Nick Wilder

A relatively approachable alpine hike with easy access.

Exceptionally popular, and for good reason. This is one of the easier ways to enjoy a high alpine lake, beautiful forest, and good sense of the Indian Peaks Wilderness. It's popular, so expect company.

Need to Know

Trailhead parking is extremely limited, and there are no good alternatives when it's full. Take the free shuttle from the Nederland Park and Ride (just west of downtown). Use this parking symbol to navigate to the Park and Ride


From the trailhead, cross the footbridge and take the Devil's Thumb Trail #902, which climbs steeply for about 0.5-miles on an old road. The shorter Devils Thumb Bypass turns right (north) in 0.8 miles, but stick left and you'll soon come to the Lost Lake Trail.

Beautiful forested trail continues and you'll quickly get to the lake. There are 9 campsites available (first come, first served, and popular). It's cold, but people have been known to take a dip. Fishing is also popular.

Enjoy the views, circle around the lake, and meander back down!

Good hike! Parking was annoying (we had to double back to town and take the shuttle) but the hike was a good length and difficulty

7 weeks postpartum and the incline was a little challenging for me. Could be a great trail to take visitors from Nebraska
