Escursionismo a Wallerstein

There is an error in the map. On the path out of Fremdingen the path comes to a sudden stop and there is a barrier where it ends, with a nearly vertical drop down to the road (25). My first photo shows the view of the barrier and the drop from the other side of the road. The second photo shows my position marker at the barrier. The third photo shows the new correct route, leading to a tunnel under the road.
