Where is the olm?
Olms are naturally shy. The best chance to see them is when you visit the cave early in the morning.
Fascinating river cave with rare creatures
The Hermanns Cave was discovered by chance during road construction work in the 19th century.
Just a five-minute walk from Baumanns Cave, it impresses not only with its large amount of unique formations of stalactites and stalagmites, but also with its huge cavities up to 50 meters high. Special highlights in the Hermanns Cave are the Olms Lake, in which Germany’s only olms live, and the sparkling crystal chamber.
During a tour (with or without a guide, depending on the current offer) you will find out everything you need to know about the Hermanns Cave, its stalactites and the cave dwellers in around 50 minutes.
