A 37.1-mile point-to-point in Pennsylvania, with 557 ft of climbing. Reaches Springdale Lake and other lake/viewpoint destinations. Managed by Pennsylvania DCNR.
The climbing is spread fairly evenly along the route. It gives back about 6,028 ft along the way, so it rolls rather than climbing steadily.
