Marble Run at Herrenbachstausee

What I really like about the circular route around the Herrenbachstausee: The marble runs are all rather short, or have a stopper installed on longer stretches, so that even younger children have a lot of fun because the ball doesn't roll too far away from them. The marble run elements are all very different and very lovingly designed. Many are decorated with wooden animals. In addition to the marble runs, there are older elements such as a labyrinth, a goblin gorge or a stalking trail. Some of them are a bit old but still interesting.

Great marble runs for the kids

One of several short marble runs around the Herrenberg reservoir. My children had fun. Unfortunately, the track is no longer completely flat and the ball falls out of the track every now and then.
