The gap between the rocks of the Goldfralay massif is as narrow as a towel. They rise a good 20 meters. Source: https://www.fr.de/ratgeber/reise/mullerthal-bizarre-felsen-tiefen-waeldern-11692771.html

Beautiful and this is located exactly behind the MartBusch campsite. The view from the viewpoint further on is much better, this is more of a rest spot because you don't see much of the vegetation here anymore.

Towering rocks through which several crevasses and the robber's cave lead and up to the plateau with a view. There are several variants to discover. Maximum experiences in the smallest space! You can create an extremely interesting tour of 5km, but also easily over 30km!

The rocks are a true labyrinth of paths and paths, you can go in between and if that doesn't work outside. Something for everyone. Often a light is also useful, some gorges are very dark. And the GPS doesn't work well here
