It's cool to see these unusual opportunities for climbing. I have to remember that place and sneak my harness into the car if we go to the Rhine :-D.
This route is nice, has a great view, but it is not very sportive or spectacular. Don´t be disappointed. But I think it is a good idee of some small cities to get more tourist in town. Greets Sebastian
Forget about bringing a harness, otherwise you really perhaps will be disappointed -- this is no real via ferrata, more a hike with short ferrata-type sections, which nearly (?) all can be avoided.
