Tailwater Trail

William H. Harsha Lake and East Fork State Park offer an extensive trail system for hikers, bikers and horseback riders, with over 70 miles available for short rambles or several-day jaunts. In the Corps Operations Area, hikers will find access to three trails. The North Entrance to East Fork State Park gives access to many miles of bridle trails open to hiking plus two walking trails in the Campground. The South Trailhead Access Parking Lot is the main staging area for hikers, backpackers and mountain bikers alike. Also located in the South Entrance to East Fork State Park are three walking trails. Trail Maps showing trailheads may be obtained from East Fork State Park and the U.S. Army Corps of Engineers.
