You will begin your exploration by visiting the upper part of the Caves which is rich in speleothems and impressive with its voluminous rooms.
Then you will descend an 80m chasm to reach the bed of the river and change the setting. You will then be in the bowels of the Earth where you will be able to observe the erosion work that water has done and continues to do today. After a boat ride on the underground river, you will board a small train for the last 700 meters of the Caves.
Upon leaving, you will have crossed the mountain and experienced a unique trip in Europe.
