Mike
December 22, 2025, Rock Walls and Cave on the Slope

Rugged rock faces and a small cave rise up along the slope, revealing the landscape's raw, untouched character. The exposed rocks tell a story that goes back far beyond human history: formed by geological processes, worn away by water and weather, and slowly exposed by erosion. The cave itself feels like a natural shelter, cool and sheltered, evoking images of a time when such places served as refuge, storage, or simple shelter.

The Heinrich-Stollen near Zweifall was operated from 1847 to 1866. The adit is located in the colourful slates with conglomerates of the Gedinnian (Lower Devonian). The rocks are red and green, fine-grained silty slates that are schistose. Iron ore was mined. A small plaque explains the ore mining and the trip hammers of the region.

In my opinion, it's more practical. If you park at the foot of the Schlangenberg, you'll have the Schlangenberg behind you at the beginning of the hike and can walk past it on the way back. Theoretically, you could walk past the Schlangenberg both times, but that's not recommended.

The path here is very overgrown in the summer and a thick tree trunk lies in the middle of the path.

The ore gallery is located a little off the main path. Once you have completed the path, you can see the ore gallery and the information board.

When exactly this underground facility was built is not known. But from the 19th century it is known that a local brewery from nearby Gey used the corridor and vault system to cool their products. Hence the name Bierkeller. Today closed to the public as a home for bats.

Somewhat hidden in the forest, you have to be careful not to drive past it. An information board explains what used to be funded here.
