With one foot in Pennsylvania and the other in New Jersey, the place where the Delaware River makes a tight S-curve through the ridge of the Kittatinny Mountains was, in the days before air-conditioning, a popular resort destination. In the modern era it remains an area of surpassing dramatic beauty, a slice of rugged wilderness within a day's trip of the largest urban conurbations on the North American Eastern Seaboard. The current preserved areas dates to 1965, when the Delaware Water Gap National Recreation Area was established, covering land in both NJ and Pennsylvania.

Note that entrance to the park is free, but there is a $10 fee for cars and a $2 fee for bicycles.
