Kakus Cave and Kartstein Cliffs

Highlight • Cave

A very large cave with many exits, so a lot of light falls into the cave. It is also very bright and, with stairs and concrete reinforcements, can be entered even by fearful people (claustrophobia, darkness, etc.) In the back part - up the stairs - you can crawl out on your knees by lowering. The various openings of the cave have something like windows, so no artificial light is necessary during the day

The softer rock was created by karstification.

For a long time the Arnulphus Chapel stood high up on the mountain, visible from afar in a barren landscape. It was a place of faith for pilgrims who prayed for the health of their cattle and at the same time parish church for the villages of Walsdorf, Zilsdorf, Loogh, Stroheich and Orendorf. It was consecrated to Saint Arnulphus, the patron saint of millers and brewers. At the beginning of the 19th century the chapel fell into disrepair. Soon all the stones were removed and the bones of the deceased in the cemetery in Walsdorf were reburied. There is now a deep hole at the site of the former church. The mountain has given way to a basalt mine, which nature is now taking back after the work has ended.

The only reminder of the church was a processional cross on the way up. But in 1988 a saint's house was built next to it, again dedicated to Arnulphus, as a place of refuge for prayers and as a reminder of the former parish church.

A little north of the two villages of Walsdorf and Zilsdorf is a highlight that every visitor to the Eifel with at least a little geological interest should have on their wish list: The Arensberg volcano. Since this is created separately (and unfortunately, multiple times in the komoot system), here is only the access, a tunnel of non-natural origin. A covered passage has been created to protect visitors from possible falling rocks.

Kakushöhle Cave

Highlight • Cave

The cave itself is of course not suitable for road bikes - although you can take your bike with you.
Snack is good - there aren't that many in the area.
The toilets (outside) allow water intake.

A beautiful passage into the interior of the volcano. Especially since your eyes have to get used to the lighting conditions. You walk into this tunnel almost blind. There's something mystical about it.
