Let yourself be enchanted by the secret of Fosse Dionne! In the heart of commune of Tonerre, this vaucluse spring has kept its origin secret. It is associated with many legends. After folllowing a complex course underground, the spring forms a basin. At the bottom, you will be able to make out the entrance to an underwater tunnel. The tunnel goes on for 360m to a depth of 61m.
