During the eruption of the Bausenberg Volcano, which lasted only a few weeks, a cinder cone was formed. Lava bubbled inside the volcano, then broke through the weakest side of the cinder cone, and flowed out northwards. This is how the volcano gained its characteristic horseshoe shape.
To this day, the Bausenberg is the best preserved horseshoe crater of the Eifel! There is a large variety of different biotopes in the crater and around its rim. The mountain in Niederzissen’s backyard provides a home for well over 500 species of plants and more than 5,000 different species of animals and is protected as a nature reserve. Discover this natural landscape on a pleasant walk round the rim of the crater.
