San Juan NF — Mancos-Dolores RD

The Rosalie Trail is a 26.2-mile out-and-back route located in Colorado near the town of Colorado, managed by the San Juan National Forest's Mancos-Dolores Ranger District. This extended backcountry route features a total elevation gain of 2,326 feet, offering a moderate climbing challenge spread across the full distance. The out-and-back format allows hikers to turn around at any point and return via the same route, making it accessible for those seeking shorter day hikes or longer backpacking expeditions. The relatively modest elevation gain relative to the trail distance means steady, manageable grades throughout most of the route. This trail provides access to the San Juan National Forest's remote terrain, suitable for hikers with intermediate to advanced fitness levels given the overall distance. The trail is maintained by the Mancos-Dolores Ranger District, part of one of Colorado's largest national forests. Hikers should prepare for the extended distance and bring adequate water and supplies. Current trail conditions and seasonal accessibility information is available through the San Juan National Forest's official website.
