Kiosks and signs provide interpretive materials for trail users.
The visitor center is an impressive facility, free to the public, Americans with Disabilities Act-compliant, and accessible by public and private transportation. The facility is visited by many schools and conservation organizations for classroom use and meeting space. The exhibits highlight the plants, wildlife, and their habitats found at John Heinz NWR. The building is also an important example of sustainable design and environmentally friendly construction.
The 4.5 mile tidal segment of Darby Creek that flows through the John Heinz National Wildlife Refuge at Tinicum is unique and scenic. It winds through the largest remaining freshwater tidal marsh in Pennsylvania, which allows canoeists to see a variety of plants and animals. The refuge waters are tidal and navigable only within 2 hours before and after high tide. Visitors must provide their own canoe/kayak and life vests.
