The Highline Trail is a 25.8-mile out-and-back route located in Colorado near Colorado, managed by the San Juan National Forest's Columbine Ranger District (East). This extended backcountry trail offers hikers an immersive experience in the high country of southwestern Colorado's San Juan Mountains. The trail's out-and-back structure allows flexible hiking options, enabling visitors to turn around at any point rather than committing to the full distance. This format makes the route accessible to hikers of varying abilities and time constraints. The considerable length of nearly 26 miles makes this a challenging day hike or an ideal multi-day backpacking trip. The San Juan National Forest setting provides scenic mountain terrain characteristic of the Colorado high country, with abundant wilderness opportunities. The Columbine Ranger District manages this area to balance recreation with conservation. Hikers should prepare for a backcountry experience with appropriate gear and supplies.
