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 Bronner Cave is located just below Bronnen Castle and surprises with its size and height.

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.

Not to be despised as an ascent either. Exhausting, but with a promising reward when you reach the top.
