More than 200 miles of the Delaware River are the centerpiece of two units of the National Park System, three federally designated sections of Wild & Scenic River, and a National Heritage Area. These areas are the focus of many environmental and historic conservation efforts.
The park operates in cooperation with many organizations. Those within the park may be operating under an MOU. (Memorandum of Understanding) Those doing commercial business in the park may be operating under a business permit.
