Lost Lake (9,850′), Front Range
Lost Lake is an alpine lake surrounded by the majestic mountains of the Indian Peaks Wilderness. It’s a perfect destination for a day trip. The lake’s crystal-clear waters are a popular spot for fly fishing. Keep an eye out for a glimpse of moose, which are commonly seen along the trail
Lost Lake is located just outside of the Indian Peaks Wilderness Area, therefore, wilderness regulations do not apply. You may camp without a permit in one of the established camping spots. You may also bring your dog, a leash is required.

Trail Directions
From the Hessie Trailhead, cross the footbridge and take the Devil’s Thumb Trail (#902), which climbs steeply for about a 1/2 mile on an old road. Do not take the Devil’s thumb Bypass, which turns right (north) in 0.9 miles, just before the bridge. Instead, cross the bridge and stay on the main Devil’s Thumb Trail.
It is 1.1 miles from the trailhead to the Lost Lake Trail junction. Turn left (south) following signs for Lost Lake Trail #813. The lake is up another 1/2 mile on a good trail.
