Use this doubletrack dirt & rocky road to gain elevation above the upper Castle Creek Valley all the way up to Taylor Pass. Passenger cars can park at the informal trailhead parking area (100 yards from Castle Creek Rd.), prior to crossing the wooden bridge across the creek.
Rocky portions of the road may cause you to hike some of the steepest portions on the way up. Expert riders will love blasting down the nearly 5 miles when riding back down to the lowest elevation of the road.
