A River and its History

The Delaware River, the largest free-flowing river in the eastern United States, runs past forests, farmlands and villages. 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.
