Head for the Wissahickon and join Brad Maule for a loop hike of the park’s greatest hits. We’ll descend the Cresheim Valley, stop at Devil’s Pool, cross Fingerspan, and come back into civilization through Carpenter’s Woods. Meet at Allen Lane train station. Ride the Chestnut Hill West Line there (the train arrives at Allen Lane at 9:45), or you can bike or drive. Parking is available on Cresheim Road, Nippon Street, and Mt Airy Ave near Allen Lane train station. Please do NOT park in the train station, as it is used for the High Point Café inside. Bundle up, bring water (and a snack if you like), and wear sturdy boots.
