The Wissahickon Valley Park is home to over 50 miles of trails for hiking, biking, horseback riding, and just adventuring in the beauty of the over 1,800 acres of beautiful park. How many trails have you explored? The All Trails Challenge and it’s challengers support FOW’s mission to conserve the Wissahickon for generations to come!

It’s simple: from August 20th to November 28th, ATC Challengers make their way through every corner of the Wissahickon.

Now is your chance to venture beyond your usual routes and explore new ones. By registering as a Challenger, you’ll have the chance to meet like-minded adventurers, maybe experience the Wissahickon in a new way, and benefit the park by having friends and family pledge on behalf of your ATC journey!
