As a part of the National Wild and Scenic Rivers System, Upper Delaware Scenic and Recreational River stretches 73.4 miles (118.3 km) along the New York-Pennsylvania border. The longest free-flowing river in the Northeast, it includes riffles and Class I and II rapids between placid pools and eddies. Public fishing and boating accesses are provided, although most land along the river is privately owned. Wintering bald eagles are among the wildlife that may be seen here. This unit of the National Park Service is also home to John Roebling's Delaware Aqueduct and the Zane Grey Museum in Lackawaxen, PA.
Almost all land along the Upper Delaware River is privately owned, so visitors must respect private property. Of the total acreage authorized by Congress, only 30.37 acres are federally owned; the remainder of the river corridor is nonfederal, with most land under private ownership.

Operating Hours & Seasons

River use is permitted 24 hours a day, year-round, unless closed due to flooding, ice floes or other hazardous conditions. Public river accesses are closed 10 PM to 5 AM. Most private liveries and campgrounds open mid-April through October. Visitor services are usually provided between Memorial Day and Labor Day weekends, and on weekends through the fall foliage season in October.
