It's not far from Prunn Castle to get to the grotto. There is climbing in the grotto. If you walk a little further you will come to a very nice viewpoint. But take good care of the children.

The settlement history of the Altmühl valley began at the beginning of the last ice age, in the so-called Würm ice age, about 80,000 years ago. On the other hand, there are no archaeological finds from the oldest phase of the Paleolithic, i. H. from the Günz, Mindel or early Rißeiszeit 500,000 - 120,000 years ago, but this is more likely due to the change in river systems. The Danube flowed through the Lower Altmühltal until about 200,000 years ago. Therefore, no older finds could be deposited in caves or rock overhangs. In the Würm Ice Age, around 100,000 - 10,000 years ago, there are first indications of people who stayed in the caves or under rock protection roofs, so-called rock shelters, in the Lower Altmühl Valley. At that time the climate here is similar to that of the tundra today. The ice-free Altmühltal was a favorable hunting ground, where mammoths, rhinos, reindeer, and later also horses, bison and primal lived. The Klausen Caves are a system of several caves nested one on top of the other: Lower Klause, Klausen Niche, Middle and Upper Klause. Except for the Lower Hermitage, tools and equipment from the Old, Middle and Upper Palaeolithic periods were found in the other caves. From the Klausen niche comes z. B. a deciduous incisor of a Neanderthal. In the middle hermitage, archaeologists from the Magdalenian layer were able to salvage a single-row harpoon, bone spikes and a perforated staff made of reindeer antlers, which is decorated with fantasy creatures. A limestone slab with incised lines of a wild horse document the first art products. In 1913, archaeologists found the skeleton of a Homo sapiens. The approximately 30-year-old man died about 18,000 years ago. His dead body was wrapped in a mighty red chalk pack. Fragments of mammoth tusks lay in the area of the skull. https://www.herzstueck.bayern/ attraction/07-station-klausenhoehlen-e617ad20c7

Somewhat hidden but worthwhile caves. However, it should be noted that access is closed from October 1st to April 30th to protect bats living in the caves.

Beautiful, easy-to-walk caves that were probably used in earlier times as living caves and for protection from the weather. You should take a lamp with you when visiting.
