Visit : Grottoes And Caves


© Yannick Bernard

One of the oldest underground cavities in Belgium dug by the 'Eau Noire' river about 300 million years ago!
The guided tour begins, in a natural setting of quite stunning beauty, at the foot of a Givet limestone cliff. Enjoy a fantastic setting and visit the two upper galleries, with their superb concretionary rock formations. During this journey, you can also admire impressive varieties of bats. The visit continues with a boat trip along the underground river, highlighted by an unusual "music & light" display, unique in Europe. Finally, enjoy the music of Vangélis and amazing stroboscopic effects.
