Four miles of the Continental Divide Trail lead to a locals' favorite downhill on the Switchback Ridge Trail. The CDT portion doesn't climb very much, but it is strewn with very challenging rock gardens. Several of them provide very difficult climbs. Get ready to session them, or to carry your bike. The rocks are the trail's defining feature, and Helenans love testing themselves on them.

Access Info

Exit Highway 12 at the Cromwell-Dixon Campground, and drive up the hill to the Continental Divide overlook. The trail starts at the stairs. There is a gate shortly after entering the forest; be sure to close it behind you. As the CDT rises into an open meadow, the Switchback Ridge Trail is to the left towards the trees. This provides the downhill connection to Tenmile Creek and Rimini Road.
