Very short steep climb, a bit difficult with a stroller, but you can get through

The caves are exciting and, according to the reservation slip, are often rented for overnight stays. In front of the caves or the impressive Nagelfluhwand, a very cool but sometimes challenging path leads through. Certainly not suitable for everyone under 80 because it also includes a very short climbing section.

It's simply beautiful here: the large semi-cave, the small waterfall with a pool above it, a small barbecue area with a view of this enchanting backdrop ... I wouldn't have been surprised if Tarzan had swung himself up on a liana.

Going down the path to the caves and climbing spots is really rewarding. Somewhat exposed but accessible to anyone under the age of 80, provided they are sure-footed.

Very worthwhile ravine with a well-developed path and impressive "Hohlen Stein". Steep places are equipped with stairs.

One of the most beautiful parts of the Thur I know. When the water level is low, you can get to the waterfall directly over the rocks. However, one should not underestimate the power of water! At this point, there have been several tricky situations, 1x unfortunately also with a fatal outcome for 2 young people.
