In Philippsthal the route leaves the Werra valley and, for the next 50 kilometres, follows the Ulster valley of the High Rhön. Along the Ulster it crosses the Thuringia-Hessian state border several times. This region was out of bounds to tourists until 1989. Tip: In Wenigentaft, cyclists can follow Waldhessen Route 14 to access (after 2 km) the 25-kilometre-long cycling route known as the Hessian Skittles (Hessisches Kegelspiel).
