Marienville is the gateway to the Allegheny National Forest and its hundreds of miles of trails for ATV, snowmobiles, hiking, and horseback riding. Each May and October, nearly 1,000 ATV enthusiasts come to Marienville for Tour-De-Forest, an organized leisure ride. The annual winter festival features an inspiring snowmobile torchlight parade. Nature lovers flock to Buzzard Swamp for spectacular wildlife and bird watching, including bald eagle and osprey.
