Allegheny National Forest

The Allegheny National Forest encompasses over half a million acres of mixed hardwood forest in northwestern Pennsylvania, forming the state’s only national forest. Much of the forest lies atop the deeply dissected Allegheny Plateau, where ancient river systems carved valleys and ridges over hundreds of millions of years. Glacial activity bypassed this region, leaving old, stable soils and a rich diversity of hardwood species such as black cherry, red maple, sugar maple, beech, and oak. The forest is especially known for its extensive black cherry stands, a legacy of both natural regeneration and mid-20th-century timber recovery efforts. Recreation opportunities are abundant: hundreds of miles of hiking trails, extensive ATV and snowmobile networks, paddling along the Clarion and Allegheny Rivers, and fishing in cold-water streams and warm-water reservoirs. The Allegheny Reservoir (Kinzua Dam) is a major regional recreation hub offering boating, camping, and scenic shoreline access. Dispersed camping is widely permitted throughout the forest, with the exception of certain high-use corridors and developed recreation zones. Visitors enjoy backpacking routes, remote stream valleys, and quiet ridge camps. Dense hardwood canopy provides excellent fall color, and wildlife includes black bear, white-tailed deer, bobcat, fisher, and diverse bird populations associated with mature forest systems.
