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 Lourdes Grotto was built in 1903 on the initiative of Father Hesseler, the parish priest of Rohren. It is an expression of the deep piety and trust in God of the people. Even today, the grotto is a destination for pilgrims who implore the Virgin Mary for help in times of need.

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.

The Olberg Grotto was built by Pastor Hesseler in 1904. The plans were drawn up by Father Rademanns of Steyl. Wagoners from Widdau and Rohren brought approximately 80 loads of rubble and approximately 30 loads of sand from the Rur. The grotto was built by the local community using manual labor, thus saving the elderly and infirm from Widdau the strenuous walk to the church in Rohren. Source: Display board.
