Grasslhöhle has been known for centuries. Just inside the entrance there is a veritable forest of stalagmites. The heart of the cave is the Dome with numerous cascades of stalagmites. The so-called Giant is 3 m thick and 10 m high. There are galleries running along the sides of the Dome which display a rich array of speleothems.

Grasslhöhle is easy to explore and gives children in particular an impressive insight into the beauty and fascination of such a cavern. Whoever intends to visit both Grasslhöhle and Katerloch should make a point of inspecting the considerably smaller Grasslhöhle first in order to fully appreciate the grandeur of the Katerloch afterwards.
