Welcome to Wissahickon Valley Park!

Designated a National Natural Landmark in 1964, the Wissahickon Creek gorge is one of the most unique places in the City of Philadelphia. Carved through the distinctive Wissahickon Schist bedrock, the gorge features steep wooded hillsides where the region's rich history is represented in the park's many beautiful sculptures and historic structures, including Philadelphia's only remaining covered bridge.

The Wissahickon trail system features over 50 miles of premier biking, hiking, and equestrian trails and is a designated National Recreational Trail.

Park Stories

Protecting the Wissahickon Watershed
The Wissahickon Creek Watershed encompasses 64 square miles in Philadelphia and Montgomery counties and includes all surfaces that direct water into the creek, such as green spaces, rooftops, and roadways. When rainfall flows across

these surfaces, it transports leaves, soil, and pollutants (such as oils, fertilizers, and trash) into the Wissahickon. These pollutants decrease the overall quality of water in the creek, which is a major source of Philadelphia's drinking water.

The Fairmount Park Commission, now Philadelphia Parks & Recreation, was established in 1868 to ensure a clean source of drinking water for Philadelphia and the surrounding area. Today, the department, with the help of many groups, manages our parkland whose vegetation helps filter and absorb pollutants from stormwater runoff while reducing erosion. This vegetation also provides cooling shade for creeks, improving the habitat for fish and other aquatic organisms.
