Discover the longest underground waterway in the world that is accessible to tourists! This trip back by boat over the river that runs 700 meters through the bottom floor of the cave is a true experience. It forms the conclusion of the visit in which you have witnessed various underground miracles, such as spectacular corridors, beautifully decorated by mother nature, and a room that was discovered in 1912: the Cathedral. This is no less than 40 meters high, and it could easily accommodate a 12-storey building. The cave, which has been visited since 1828, is now even more beautiful thanks to the recently renewed lighting.
