The cave can be visited by appointment or on Ascension Day. The climb from the Mühlheim cemetery to the cave takes about 25 minutes. A narrow path leads there. There is a bench in front of the cave. You have a wonderful view of the Danube valley towards Mühlheim - Tuttlingen.

Impressive cave. I wasn't sure if you're really allowed up there because of the caution tape lying around. Has it been demolished or can you go up again? I then tried it cautiously, although the stairs with a missing step only seemed trustworthy to a limited extent.

The cave is open and illuminated once a year on Ascension Day and is a special experience. Except for a few ladders and chains, it is not developed and is a bit more demanding for those who have no cave experience. Some places are very slippery, the chains help there. At the back, a ladder descends several meters almost vertically. In any case, our trousers and jackets had to be put in the washing machine afterwards. But the visit was fun. We know visitor caves well enough, but this cave is different.

Not far from Beuron Monastery, the Danube Mountain Hiking Trail leads over an almost flat Way of the Cross to Liebfrauental. At the end of the Way of the Cross there is a rock grotto with a figure of the Virgin Mary: the destination of the Assumption Day procession. The many benches are also ideal for resting or simply unwinding.
