The Allegheny River is a river in Pennsylvania, managed by the USDA Forest Service Allegheny National Forest and the Pennsylvania Fish & Boat Commission. It runs about 0.3 miles from the town of Tionesta, making it an easy addition to a trip through the area. For comfortable weather, late spring and early fall are the best bets. Typical averages from a nearby weather station show May highs around 72°F and September highs around 75°F, with July the warmest month at about 83°F. Tionesta Rec. Area Campground sits about a mile away, and Outflow Recreation Area, a lake fishing spot, is about 1.5 miles off. Eagle Rock Ridge Boulders, a climbing area, is roughly 6 miles away.
