In this tour we visit the 550-meter-long underground World War II fortress and offer you the opportunity to try abseiling – descending a rock face with a rope. The fortress remained unfinished and is therefore a unique combination of architecture created by both man and nature. And that is not all. Until a few years ago, this building was forgotten and hidden. It was only recently discovered, put to rights and equipped for visitors. Depending on the difficulty level of the abseiling you want to try and you feel comfortable with, we offer this tour in 2 versions: Abseil and Abseil Plus. Abseil Plus In addition to the first two descents, there is also a descent on the cascading rock inside the fortress. Since that rock is a bit uneven and slippery, the descent is somewhat more demanding. Participants can prepare for this descent by executing the first abseils with the backup of an instructor. In this way, the feeling for the technique and sense of security are gradually acquired. On this tour, you can also try a simultaneous abseil in pairs. If this feels too much for you, check out our offer and book TOUR THE UNDERGROUND WITH NO EXPERIENCE REQUIRED Abseil tour
