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.

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.
