Lavagrotte Ernstberg
Hinterweiler
To discover the lava grotto on the Ernstberg, you have to embark on an adventure into the depths. As you descend, you will witness the volcanic activity in the volcanic Eifel with its rugged basalt and bizarre lava rocks. The entrance to the cave is about 200 metres below the summit. Once at the bottom, you can listen to the legend of the "Kleintheischen", a labourer who never returned from a cave in Ernstberg a long time ago... they say.
From the Middle Ages until around 1930, millstones were quarried at the foot of the Ernstberg.
The lava grotto is an option to change the perspective on a hike along the Ernstberg Panorama Trail.
