Horn Peak Trail in Colorado's San Juan National Forest offers a challenging 6.6-mile out-and-back route with 3,150 feet of elevation gain. Managed by the Gunnison Ranger District, this trail demands significant physical conditioning due to its steep grades and substantial vertical climb. The out-and-back format means hikers will cover the same terrain on the return journey, providing familiarity with the route. The combination of distance and elevation gain creates a strenuous day hike suitable for experienced hikers with good cardiovascular fitness. Located within the San Juan National Forest near Colorado, the trail provides access to the high country typical of this region's alpine terrain. The elevation profile indicates sustained climbing throughout, requiring steady pacing and adequate preparation. Hikers should come equipped for high-altitude conditions and changing weather patterns common to Colorado's mountains. The trail's difficulty level makes it important to start early and allow sufficient time for the round trip before darkness falls. Spring and summer months typically offer the best hiking conditions when snow melt permits safe access.
