A very beautiful natural cave. If you are brave, you can also take a detour to the "Cave in Hell" (it really means that 😃), but you should be sure-footed, while the Hohlenstein Cave is very easy to reach.
A beautiful path leads on the steep wooded north slope of Michelsberg to the small cave Hanseleshohl. It was probably a cult and sacrificial site in the Neolithic period.
