From the parking area at Trotting Park Road, ride straight past the gate, cross a jeep road and look for the start of "Hidden Zipper" almost immediately on the left. Ride over a small rock ledge and enjoy the flowy singletrack with several short climbs and drops.
At the trail intersection, stay right on to the AmeriCorps trail.
