Starting from the trailhead, hikers ascend through forest terrain with steady elevation gain throughout the route. The 2.4-mile push to the lake rewards trekkers with views of the high country landscape typical of the Rio Grande National Forest region. The out-and-back format means you'll retrace your steps on the return, totaling approximately 9.6 miles round trip with consistent elevation change. This trail is suitable for hikers with moderate fitness levels who are comfortable with extended climbs and higher elevations. The destination lake provides a scenic turnaround point and opportunity to rest before heading back down.
