About Lost Falls
Lost Falls tumbles through a quiet, forested pocket of Rocky Mountain National Park, offering a peaceful reward after a lively mountain hike. Nestled within the park and managed by the National Park Service, the falls sit amid stands of subalpine forest and feel pleasantly remote—an inviting spot for photographers and anyone looking to trade trail noise for rushing water and dappled light. The approach to Lost Falls follows a moderate out-and-back route of about 3.0 miles round-trip with roughly 500 feet of elevation gain, so it’s well suited to hikers with some experience who want a half-day outing. If you’re planning an overnight stay, Tom Bennett Campground is nearby (about 7.98 km), making it easy to combine a campsite evening with an early- or late-day visit to the falls when crowds are smaller and the light is best.
The Setting
Lost Falls sits at 9,885 feet within Rocky Mountain National Park, in the high alpine of Colorado.
