Highline

The Highline Trail is a 25.8-mile out-and-back route in Colorado's San Juan National Forest, managed by the Columbine Ranger District. With 1,204 feet of elevation gain spread across the full distance, this trail offers a moderate climbing challenge suitable for hikers with solid endurance. The relatively gradual grade makes it accessible for a full day of hiking without extreme technical difficulty. Located in the Colorado high country, the Highline Trail provides extended mileage for those seeking a substantial backcountry experience. The out-and-back format allows hikers to turn around at any point, making it flexible for different fitness levels and time constraints. The trail is maintained by the San Juan National Forest Service. This route is ideal for hikers looking to spend significant time in the wilderness while enjoying consistent forest and mountain scenery typical of the San Juan range. The 1,200-foot elevation gain is distributed throughout the journey, preventing steep sections from dominating the experience.
