Welcome to the Allegheny National Forest!

Winter on the ANF



Established in 1923, Allegheny National Forest (ANF) is Pennsylvania’s only National Forest. Situated in the foothills of the Appalachian mountains, the ANF is composed of plateau tops with elevations up to approximately 2,300 feet and valleys down to approximately 1,000 feet above sea level. The forest is approximately 517,000 acres and includes land in Elk, Forest, McKean and Warren counties in the northwestern corner of the state. The U.S. Forest Service brought new concepts in forest management to the Allegheny Plateau -- multiple benefits and sustainability. The motto "Land of Many Uses" captures the National Forest goal of a healthy, vigorous forest that provides wood products, watershed protection, a variety of wildlife habitats and recreational opportunities -- not only for us today, but in a sustainable way so future generations can enjoy these benefits, too.
