Trail is hard to follow at fist but there are some Kokopell's painted on the rocks and the trail snakes up the hill. First part of the trail is slick rock and then it turns into dirt single track.
Turn off highway 220 to Alcova lake shore drive. Follow road to the canyon and it stops at the parking area. Start riding up the canyon rim.
