The Iberg stalactite cave is located in the middle of the Iberg, a limestone massif that originally emerged from a limestone reef around 380 million ago. Some of the former reef inhabitants are still preserved as fossils on cave walls and can be discovered on a guided tour. During the approximately 30-minute guided tour, you will also learn why the Iberg stalactite cave is a rare type of corrosion cave, about the cave's history of exploration and which residents it once and now houses. In addition to the show cave, which can only be visited as part of a guided tour, you can also visit the three exhibition rooms with the themes “Fascination of Caves”, “A Traveling Reef” and “The “Oldest” Family in the World”. Admission always includes a cave tour. Adults pay 10 euros and children and young people up to 17 years pay 6.50 euros.

Bears have never lived in the Bear Cave and it is not a natural cave, but a man-made cavity that was created to mine slate. You can only enter the beginning of the cave, then a protective grille is attached.
