About FOW

The Friends of the Wissahickon, official park partner of Philadelphia Parks and Recreation, conserves and improves the 1800-acre Wissahickon Valley Park. Our 2,700-strong membership has supported the wild beauty of the park since 1924. Staff and volunteers work with expert contractors and environmental scientists to mitigate stormwater runoff into the watershed, reduce erosion, and address the impacts on the native habitat posed by climate change: volunteer hours and membership dollars support our work to sustain this special urban oasis.
