Route Description for South Sourdough Trail
Sourdough Trail is a straightforward out-and-back trail that travels through the beautiful Roosevelt National Forest. From the trailhead, the trail steadily climbs and gains elevation from its starting point of 2,804 m.
After a brief level section of the route at a clearing in the trees, the trail will soon have you digging deep and gasping for breath as you continue to climb. After about 488 m of climbing, the trail levels off and starts to trend downhill.
The end of the trail puts you at the gate for the Brainard Lake Recreation Area within the Indian Peak Wilderness. The way back is to follow your tracks back down to the trailhead.
