Go up Straße "Am Anger" and at the end of the street you will find "St. Georgen" go left here and right onto the gravel path. When on the right hand side you find a wooden sign engraved "Ursulas Umkehr" Go right through the field path to the end of the field, (the path continues, but don't take it further) Jump the fence and hike the creekbed, there should be a noticeable path leading upstream. When you see an old piece of rope, cross to the lefthand side of the creek and follow the path up left. You will come upon a stone almond and a yellow ski in the ground. From here go up and left until you stand before the wall. (whew did you make it?) Check the google map for precise coordinates.
