Panorama of Lost Lake snowshoe trail in Indian Peaks, Colorado

The snowshoe or winter hike to Lost Lake is not as daunting as the name suggests. Lost Lake is a very popular, family-friendly winter hike but that does not mean it is not worth checking out if you are not towing behind a kid or two. It offers great mountain views along with some mining history at both the trailhead and the destination!

Route Description for Lost Lake

Lost Lake is a moderately easy winter hike that begins at the historic Hessie Townsite; an old mining town high in the Rocky Mountains. The Lost Lake hike offers a lot of bang for your buck, so to speak. Great views and can easily be done in a day with plenty of time to spare.

Begin the trail at the closed gate, hiking along the closed County Hwy 130 towards Hessie Trailhead, where there is a sign and map of the surrounding area. Follow the signs for Lost Lake, crossing over a bridge and onto a pretty hike through pine forests and aspen groves. A couple of switchbacks past an old log cabin has you gain elevation alongside an impressive waterfall.

A short side trail spurs off from the main trail to a waterfall overlook point (worth the view)! Continuing on to Lost Lake, you will descend down into a small valley crossing over a bridge to the base of a second smaller waterfall. From this point, the trail climbs the other side of the valley all the way up to Lost Lake. From the lake, you will enjoy views of Mt. Neva and Mt. Jasper off in the distance.

Return the way you came.
