Keyser Ridge is a 25-mile out-and-back trail located in Colorado near the White River National Forest, managed by the Aspen-Sopris Ranger District. This backcountry route offers experienced hikers an extended wilderness experience through the national forest landscape. The trail's length makes it suitable for backpacking trips or very ambitious day hikes. Hikers should prepare for a full day or multi-day journey when tackling this route. The out-and-back format means you'll retrace your steps on the return, allowing you to choose your turnaround point based on time and energy. Located within the White River National Forest, the trail provides access to the Aspen-Sopris area's backcountry terrain. This region is known for its mountain scenery and wilderness character. Given the trail's distance and remote nature, proper preparation is essential, including adequate water, navigation tools, and physical conditioning. Contact the Aspen-Sopris Ranger District for current conditions, trail restrictions, and any updates before your visit. Permit requirements and seasonal closures may apply.
