Allegheny National Recreation Area is a protected recreation area on the Allegheny Plateau in northwestern Pennsylvania within the Allegheny National Forest, managed by the United States Forest Service. Established by the Pennsylvania Wilderness Act of 1984 as Public Law 98-585, with support from Congressman Bill Clinger, Senator Arlen Specter, and Senator John Heinz, it encompasses 23,100 acres in three separate parcels. Its two main units lie around the Allegheny Reservoir upstream from Kinzua Dam and south of Warren along the east bank of the Allegheny River. It preserves public access to a broad forest, reservoir, and river landscape in a prominent federal forest area.
