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. In December to June and September from Tuesday to Sunday and on public holidays, the Cave Adventure Center is open from 10 a.m. to 5 p.m. In July, August and October it is even open to visitors every day from 10 a.m. to 5 p.m.

Iberger stalactite cave awaits the visitor with stone secrets that are millions of years old in a modern setting as well as a journey from the Paleolithic to the Middle Ages. The Iberg, which consists of a limestone massif, is located above the town of Bad Grund. In the adventure center you walk on a 160 meter long path blasted into the mountain directly through the ancient reef. The most important attraction of the Cave Experience Center is the Iberg stalactite cave.
