Due to a technical problem, the boat trip across the lake (approx. 100 m) is temporarily suspended.
The Grottes can still be visited in their entirety, however. A path running alongside the lake allows you to discover this section on foot, without altering the beauty or interest of the route. You can continue to enjoy the underground galleries, the impressive geological formations and the train ride at the end of your visit.
We thank you for your understanding, and look forward to welcoming you for an incredible underground experience.
