Lost Lake Trail, Mountain hiking trail in Larimer County, US
Lost Lake Trail is a hiking path in Larimer County that winds through mixed forests and follows a creek to an alpine lake. The route passes through different woodland environments as it climbs toward the mountain destination.
The trail was established in 1934 by the National Park Service with architect Allison van V. Dunn contributing to its design. This early project reflects how mountain access developed for outdoor recreation in Colorado.
The trail stands as part of the National Register of Historic Places, representing early recreational development in Colorado's natural spaces.
The best time to visit is between June and October, as the access road closes during winter months due to snow. Visitors should plan accordingly and check conditions before heading out.
Multiple camping spots dot the trail near a small pond and creek system, allowing visitors to spend several days exploring. This overnight option draws those seeking extended mountain experiences away from developed facilities.
