Rainbow Lake Trail is a 7.9 mile moderately trafficked out and back trail located near Walden, Colorado that features a lake and is rated as difficult. The trail is primarily used for hiking and camping and is best used from June until August.
Descending the steep ridge that contains South Baldy, Middle Baldy and North Baldy Mountains, Rainbow Lake Trail drops 1,400 feet in two miles. This descent brings users into the steep West Elk Creek drainage. The trail crosses the creek, forks and climbs the other side of the gulch. The right fork brings hikers to Sun Park and Coal Mesa Trails within two miles. The left fork follows the northern shore of the stream for one mile then ascends the ridge that leads to Coal Mesa Trail, 451.
