Wissahickon Valley
Wissahickon Valley Park is a 1,800-acre park along the Wissahickon Creek in Northwest Philadelphia, preserving a dramatically wooded gorge that seems far removed from the surrounding city. The park, part of the larger Fairmount Park system, provides hiking, biking, horseback riding, and nature study along miles of trails winding through terrain that has remained largely unchanged since before European settlement. The Wissahickon's natural beauty and accessibility make it one of Philadelphia's most treasured landscapes.[1]
Geography
The Wissahickon Creek flows approximately 24 miles from its headwaters in Montgomery County to its confluence with the Schuylkill River near the Philadelphia Museum of Art. The creek's lower seven miles, within Philadelphia, have carved a deep gorge through the bedrock, creating dramatic terrain with steep hillsides, rock outcrops, and the creek itself cascading through the valley.[1]
The Wissahickon schist—the gray metamorphic rock visible throughout the park—gives the area its distinctive appearance. Outcrops along hillsides, boulders in the creek, and exposed rock faces create a rugged landscape that contrasts with Philadelphia's urban surroundings.[1]
History
Early History
Lenape people inhabited the Wissahickon Valley before European settlement. Early European settlers built mills along the creek, exploiting water power for grinding grain and other manufacturing. The ruins of several mills remain visible within the park. The valley's terrain made it unsuitable for dense development, preserving its character even as surrounding areas urbanized.[1]
Park Establishment
The city acquired the Wissahickon Valley in 1868 as part of Fairmount Park's expansion, protecting the creek from industrial pollution and development pressure. The protection came early enough that the valley retained natural character that development would have eliminated. Management has emphasized conservation, with less development than other park areas.[1]
Forbidden Drive
Forbidden Drive, the main trail along the creek, follows the route of a colonial-era road for approximately five miles from Northwestern Avenue to Lincoln Drive. The name derives from prohibition of automobile traffic—the road is "forbidden" to cars. The wide gravel path accommodates walkers, runners, cyclists, and horseback riders in a shared-use arrangement.[1]
The drive's relatively level grade along the creek contrasts with the steep terrain visible on both sides. This accessibility makes Forbidden Drive the park's most popular route, drawing visitors throughout the year.[1]
Trail System
Beyond Forbidden Drive, the park contains over 50 miles of trails ranging from easy paths to challenging climbs:
- Orange Trail — Climbs to the park's highest points with valley views
- Yellow Trail — Traverses the western ridge
- White Trail — Follows the eastern ridge
- Connector trails — Provide access from surrounding neighborhoods
The trail system enables exploration far from the crowded main drive, though trail quality and marking vary.[1]
Notable Sites
Valley Green Inn
Valley Green Inn, operating since 1850, provides food and refreshment in a historic building along Forbidden Drive. The inn serves as a destination for park visitors and a gathering point for the local community. The setting—surrounded by woods and overlooking the creek—creates an atmosphere unique within Philadelphia.[1]
Rittenhouse Town
Historic Rittenhouse Town preserves buildings from America's first paper mill, established by William Rittenhouse in 1690. The site interprets colonial industry and the Rittenhouse family's significance. Public programs provide access to the history concentrated at this location.[1]
