Overview

Half of Forest County, where Tionesta Lake is located, is preserved as public lands. The region is known as one of Pennsylvania's best big game regions and is home to a remarkable variety of wildlife.

Campers come to the Outflow Recreation Area Campground to enjoy the forested area along Tionesta Creek. The area is ideal for fishing, hunting as well as scenic hiking.

Tionesta is a culturally rich region with a long history. The Seneca Indian tribe named this area "where the water separates the land." Nearly a century ago, narrow gauge railways dotted the surrounding countryside, hauling out virgin timber from the hillsides.

Recreation

In-season hunting, fishing, boating, hiking and water skiing, are all available from Tionesta.

Visitors interested in wildlife viewing are likely to spot white-tailed deer, porcupine, wild turkey, osprey and opossum.
