Route Description for Lost Man Trail
Find the beginning of the trail right at the nearly hairpin bend of the road’s switchback. Climb a short ways up to the Roaring Fork River. Once you reach a small plateau you will encounter a trail junction where you will keep right to head towards Independence Lake and the Lost Man Trail.
The trail will follow the Roaring Fork River as it ascends the beautiful, lightly wooded alpine valley. Depending on the season, you may be surrounded by gorgeous wildflowers. The views and peaks that surround you are sure to provide plenty of mental stimulation to keep you motivated.
Ahead of you is the imposing Geissler Mountain will fill the horizon, and on the right you will see Twinning Peak and its impressive, expansive ridges. After gaining a few false plateaus you will finally arrive at Independence Lake, at the far edge of the valley.
Continue hiking past the crystal blue lake and up the ridge to Lost Man Pass. From the pass you will be able to peer into the adjacent valley, and you’ll be able to look down to Lost Man Lake. The trail continues down the other way, but this is your endpoint for today. Return the way you came after enjoying the splendid views.
