Rocky Mountain National Park's Lost Lake Trail

Lost Lake Trail

Description:
The Lost Lake Trail can be reached via the Dunraven Trailhead on the eastern end. The trail travels through both the Comanche Peak Wilderness and Rocky Mountain National Park. It begins at an elevation of 7,720 feet, drops down into the North Fork drainage and steadily climbs to an elevation of 10,710 feet at Lost Lake in the Park. Following the North Fork of the Big Thompson River, it intersects the Stormy Peaks and North Boundary trails along the way. The trail crosses several streams via wooden bridges. There are places to the side for horses to cross.

This trail is wide and easy to follow. Most of it travels through spruce and lodgepole pine forest. It passes through a travel zone within the Comanche Peak Wilderness. Here camping is permitted at designated sites only. Signs point the way to camp sites. The trail climbs a steep rocky incline as you approach the Stormy Peaks Trail. It leaves the Stormy Peaks intersection and travels west through dense willows and spruce. The trees begin to thin out as you climb higher. Soon you enter a large meadow, passing the trail to the Lost Meadow Campsites. The trail continues west for another 1.3 miles to Lost Lake.
