Alte Schiefergrube

in the first of the old slate quarries you can actually walk a bit in the dark tunnels

Here the flashlight on the cell phone is worth it, so that you can see where it is better not to step in order not to get your feet wet

One of the few tunnels that you can walk through, even if your feet get wet after a few meters because the gallery is filled with water.
To the right of the large cave, a small tunnel also leads a few meters into the mountain, where the traces of machining can still be clearly seen, as if someone had been drilling and hammering here yesterday.
