Berndorf lies between Hillesheim and Kerpen, southwest of the latter in the Vulkaneifel, a part of the Eifel known for its volcanic history, geographical and geological features, and even ongoing activity today, including gases that sometimes well up from the earth.
Pottenstein lies in the valley of the Triesting in the Vienna Woods and borders on Berndorf and Weissenbach an der Triesting.
