This is the southern trailhead for the Wissahickon Bike Path which connects to Forbidden Drive roughly a mile up the trail. Getting here is easy since it's directly across from the Philadelphia Canoe Club, Wissahickon Transportation Center, and just down Ridge Ave from the Wissahickon Regional Rail station. You can also connect to the Schuylkill River Trail here.
