ake Highway 89 north approximately 3 miles from South Lake Tahoe to Fallen Leaf Lake Road. Watch for bicyclists and other cars on this narrow, one-lane road. Continue 4.5 miles until you see the Glen Alpine trailhead sign and turn left. Trailhead parking is across from Lily Lake. A wilderness permit is required for day hikes into Desolation, (self register at the trailhead.) Many different hikes can be accessed from this trailhead. For a short walk, try the 2-mile hike to Grass Lake. Another longer, more strenuous hike to Lake Aloha leads you past a small waterfall, a beautiful meadow , nd three alpine lakes. A third option is a moderate hike to Half Moon, Alta Morris or Gilmore lakes.
