Wonderful abandoned basalt quarry with a tunnel in the rock.. the water level in it unfortunately prevents you from getting through at the moment

A great nature trail with display boards, which you can understand even as a layman. The access to the caves should be done better with sturdy shoes. Really worthwhile and you should definitely make a detour to the autumn labyrinth. Really worth it.

An interesting quarry with lots to discover. If you pause a bit, many animals can be observed. The entrance is sometimes under water, then access is only possible with boots or barefoot (if you dare). Quite busy on Sundays and public holidays. Worth seeing in every season.
