The treasure hole is a cave in the towering Nagelfluh rocks. At the entrance you can still walk upright, but then the ceiling comes closer and closer. After 10 meters, the cave turns left and goes another 25 meters into the mountain. You can only get there by crawling, depending on your height.
The rocks were last used in 1647 as a refuge by the villagers.
The highlight position is currently the only access to the valley basin, as a fence separates a pasture at the lower end and the rocks cannot be climbed without hooves. The boiler can then be walked about 250 m and the seclusion can be enjoyed. The treasure hole itself is on the western flank about 50 m after the entrance to the valley basin.
