With a height of 675 meters, the Hochkelberg is one of the ten highest mountains in the Vulkaneifel. It is a former stratovolcano, at the southern foot of which is the Mosbrucher pond. The mountain that is visible today was originally 200 meters below the surface of the earth. When the area was raised, the outer areas were removed, the hard basalt core was preserved in its shape. The slopes of the Hochkelberg are now covered with dense and species-rich beech forests. Remains of Roman buildings were also found there. Today there is an Eifel view on the mountain top, with a great view of the region.
