Wonderful, quiet place and you drive past too quickly - which you shouldn't do. It invites you to linger (and for those who wish, of course, to pray). I found the numerous marble plaques with thanks from the last two years of the Second World War very impressive. I hope such plaques are never needed again!

The Mariengrotte was built in 1903 based on the model of the Lourdes Grotto. In addition to its function as a pilgrimage site, it is a stop on the Kercheweg and thus a popular attraction for hikers and cyclists. A large number of birds and amphibians have also settled in its surroundings.

Very beautiful caves. Highly recommended. But you should really bear in mind that there are a lot of stairs that you have to climb back up. It is REALLY tiring for inexperienced stair climbers, so you should think carefully about it. Other than that, the entire area around it is very beautiful and informative. There is a good Italian restaurant nearby.

456 steps to reach a depth of 70m. An absolute highlight for young and old. I would pay the small fee for the photo permit again at any time. This is the only way to at least capture the experience for later 😊 The guide explained the history of the cave to us in a very exciting way. Even our little one was enthusiastic
