A very unusual sight. I have no idea whether animals or badgers live there, but the caves are now fenced off. Apparently, too many people wanted to know for sure.

I've never seen anything like this before. A bit hidden, but worth the drive.

Very beautiful caves. Highly recommended. But you should really bear in mind that there are a lot of stairs that you have to climb back up. It is REALLY tiring for inexperienced stair climbers, so you should think carefully about it. Other than that, the entire area around it is very beautiful and informative. There is a good Italian restaurant nearby.

456 steps to reach a depth of 70m. An absolute highlight for young and old. I would pay the small fee for the photo permit again at any time. This is the only way to at least capture the experience for later 😊 The guide explained the history of the cave to us in a very exciting way. Even our little one was enthusiastic

The caves are fascinating to look at, as they are buried in a clayey earth wall. I was able to think up nice stories about it, especially since the old Solmsbachtal railway line runs nearby.
