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

The second gorge after the Devil's Gorge. Not quite as spectacular, but still very beautiful.

The man-made blocks towering here, up to house-high, are evidence of a local landslide from the Born rock ledge. As the only truly native epiphyte, the Polypore Fern can be found in places with high humidity. This must have occurred a very long time ago. Recently, there have probably been no such collapses here. This conclusion can be drawn from the location and the growth of the blocks. The Polypore Fern has developed particularly well. on the moss cushions of the Born. This must have occurred in places with high humidity. This conclusion can be drawn from the location and the growth of the blocks. The Polypore Fern is also called angel-pulling. They are firmly embedded in the soil and have hardly any cavities. The limestone blocks are used to treat coughs, colds, and blockages, but too little soil material has yet accumulated for trees to grow.

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