A rock massif with two larger caves, Stadel on the left and Bärenhöhle on the right, both protruding 50 and 60 meters into the rock, respectively. Between them is a rock roof about 10 meters wide, called Kleine Scheuer. The Bärenhöhle (bear cave), as its name suggests, was a favorite place for the ice-age cave bear to roost. About 100 bear skulls and numerous fossil bear bones alone have been found here.
However, the most important site of the Hohlenstein is the Stadel, which yielded exceptionally rich archaeological finds. Tools and bone pieces of the Neanderthal man as well as the world-famous ivory figure "Lion Man", which is about 40,000 years old. The Stadel is considered the most beautiful and largest of all Lone Valley caves.
The best access to the Hohlenstein is via Lindenau to the hikers' parking lot at the edge of the forest. From there a path leads down into the Lonetal, the Hohlenstein caves are located on the right side of the valley and are freely accessible.
