The Bausenberg is a cinder cone hill, 339.8 m above sea level (NN),[1] in the East Eifel in the county of Ahrweiler in the German state of Rhineland-Palatinate.
The Bausenberg is located between Niederzissen immediately to the south and Waldorf to the north-northeast.
On 14 April 1981, the hill was officially declared a nature reserve by the regional government of Koblenz.
The reserve has an area of 127 hectares and covers parts of the parishes of Niederzissen and Waldorf.
Its purposes are to preserve the cinder cone, including its northeasterly lava flow, due to its special geological significance and also to protect, for scientific reasons, rare plant species and communities as well as habitats for rare animals.
