High Lonesome Trail - CDT Access

Begin at the Monarch Lake Trailhead. The first section of the High Lonesome Trail goes up to Strawberry Bench, through quite a bit of dead lodgepole pine, before levelling out. Some sections of this trail coincident with old roads and some active OHV use area, before approaching the Junco Lake Trailhead. Continue left, uphill, on a steep and rocky trail. The trail follows the Continental Divide through the Indian Peaks Wilderness for 6 miles. The trail terminates at the Rollins Pass Trailhead on the Corona Pass Road 149. Unlike other trails, the High Lonesome trail does not follow a major creek, so water should be carried enroute.

The trail from Monarch Lake Trailhead to Rollins Pass one-way is 17.8 miles.
