Hohlenstein Cave

Highlight • Cave

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.

Anyone who follows the trail here must be aware that it ends up becoming a real via ferrata. The beginning of the trail is like a beautiful mountain hiking trail. Towards the end, however, you need to be absolutely sure-footed and wear good shoes, especially on the descent, even if it is only a short stretch. The scenery is of course very attractive. 🧗🙂
