A deep, steep-walled gorge carved by a river, thick vegetation, rock outcroppings and waterfalls characterize Lehigh Gorge State Park. In Luzerne and Carbon counties in eastern Pennsylvania, the park follows the Lehigh River from the outlet of the U.S. Army Corps of Engineers Francis E. Walter Dam at the northern end, to the town of Jim Thorpe at the southern end of the park. Whitewater boating and biking are popular activities
