Great Egg Harbor National Scenic and Recreational River
The Great Egg Harbor River “gradually widens as it picks up the waters of 17 tributaries on its way to Great Egg Harbor and the Atlantic Ocean. Established by Congress in 1992, nearly all of this 129-mile river system rests within the Pinelands National Reserve (“Pine Barrens”). Their website mentions hiking and nature walks as activities in this area, but gives no information about where these are or about accessibility.
Here is their website. Here are assorted maps, but they don’t show trails. Headquarters’ phone number is 215-597-9175.
