Philadelphians and out-of-towners alike can find refuge from the city by way of the Forbidden Drive, a scenic expanse that extends from Chestnut Hill to Manayunk, yet feels miles away from urban life. As part of the Wissahickon Valley Park—which covers 1,800 acres—the wooded trail shelters joggers, cyclists, hikers, and even those on horseback as they explore the area's natural flora and fauna. A frequent spot for organized races, the trail is also marked by historic and geological sites.
The Friends of Wissahickson, or FOW, is a non-profit organization that started in 1924. With over 1,600 members, they work in conjunction with the Philadelphia Parks and Recreation to restore historical structures, eliminate invasive plants, monitor watershed management, and restore trails with the Sustainable Trails Initiative.
