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 Tunnel near Zweifall was operated from 1847 to 1866. The tunnel is located in the Bunten slates with conglomerates from the Gedinnian (Lower Devonian). The rocks are red and green, fine-sand siltstones that are schistose. Iron ore was mined. A small panel explains the ore mining and hammer mills in 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.
