Access
  • From Nederland, head south on Colorado Highway 119 for ½ mile. Turn west onto County Road 130 (Eldora Ski Resort sign). Stay on the main road through the town of Eldora.
  • Once the pavement ends, continue for another mile. Look for a sign and vehicles parked above a side road heading sharply down and to the left. This side road leads to Hessie TH and is a cobblestone creek bed that carries water year round. Vehicles without high clearance should park at this junction. From here, it is a ¼-mile walk to the trailhead.
  • This trailhead sees high use, especially on weekends, and parking is limited.
Trail Highlights
  • From the trailhead, cross the footbridge and take the Devil’s Thumb Trail #902, which climbs steeply for about a ½-mile on an old road.
  • Do not take the Devil’s Thumb Bypass, which turns right (north) in 0.8 miles, just before the bridge. This trail does not pass the Lost Lake Trail junction. Instead, cross the bridge and stay on the main Devil’s Thumb Trail.
  • It is 1.1 miles from the trailhead to the Lost Lake Trail junction. Turn left (south) following signs for Lost Lake Trail #813. The lake is up another ½-mile on a good trail.
