The forest was drained for many years by a dense ditch system. In order to win back the area for the site-typical alternating damp to wet forest communities and the rare animal and plant species that depend on them, the old ditches were closed and new dams were built. The result is a rewetted area in which toads and dragonflies feel very much at home. The beaver has also found ideal conditions here and is happily building dams and cave systems. He fells even the biggest trees. The area is worth visiting at any time of the year.

A nice place for a short biker break. If you take your time, you can see a lot here. Animals and plants. There are also fireplaces, so you could take a longer break.

The power plant itself interests me less. But I think it's great what has been done here to give nature back a small piece of what was taken from it. Here you can gain insights into the most astonishing water worlds and are also clearly explained on information boards.

In the 20m deep Nagelfluh cave, you can still stand comfortably at the beginning, but further back you can only continue on your knees.
