A crack in the ground just a few meters from the path. You have to fight your way through the undergrowth a little, but I think I've found the exact position.

This trail is steep. In the middle is the grotto. A beautiful place where you can't just pass by. The path is paved from the bottom to the grotto. If you have enough power in your legs, or with an e-bike, you can get up there easily

The old military rock cavern was secured with a bat gate to offer those undisturbed rest in winter. Even with a powerful flashlight, you can't see the end of the tunnel.

Here is plaster! For a long time, plaster was taken out of the mountain from deep tunnels and brought to two nearby mills on rails. A stream clouded by the plaster runs out of the tunnel. At the (barred) entrance you can see the plaster strips.
