We've been out and about and mapped a new route for you. Starting point is a 40 minute train ride away in Hersbruck.
From there on out we hike trough some lovely forest, over some hills to the highest point at about 630m. Here is a storage basin of a hydroplant. Here we can walk around and get a slight glimpse of the 200m lower lake it feeds in to.
