National Park Service, Pennsylvania.
The largest free-flowing river in the eastern United States, the Delaware River runs past forests, farmlands, and villages, and it also links some of the most densely populated regions in America. In 2000, the National Wild and Scenic River System incorporated key segments of the lower Delaware River to form this unit of the National Park System.
The Lower Delaware National Wild and Scenic River is located between Interstate 80 (at Portland, Pennsylvania and Columbia, New Jersey) and Interstate 95 (at exit 51 in Washington Crossing, Pennsylvania and exit 1 in Washington Crossing, New Jersey). In Pennsylvania, follow PA-611 and PA-32 to drive along the river. In New Jersey, follow NJ-29 south of Frenchtown for a drive along the river.
