The Allegheny National Forest sits in the rugged plateau country of northwestern Pennsylvania. Many creeks and streams cut deeply into the plateau, creating a rolling and sometimes steep topography with a 1,300 foot range of elevation. The terrain is covered with a typical eastern hardwood forest: Black cherry, yellow poplar, white ash, red maple, and sugar maple are all common to the area. The seven islands in the Allegheny River offer remote canoeing and back-country camping.
