Great cave at the end of the 1000er Stägli. The route in the cave is well marked with arrows.

Exciting place, also for children. They shouldn't be too small. You climb a bit and should bring good light.

Heideloch or Heidechuchi is a rock crevice that you can crawl through. Permanently installed iron grips provide the necessary hold. A few meters south of the Heideloch, you will find the Flädermus-Stübli. This cave is about 20 meters long and about 10 meters deep.

The Devil's Gorge begins here, through which a wonderful hiking trail leads. The Cholersbach formed the gorge, about which there are many legends. The adventurous hiking trail leads partly on footbridges over waterfalls and through caves, fun for young and old.
