Dear visitors,


We regret to inform you that our site is currently closed for reconstruction following a fire that occurred in March 2024. We are working tirelessly to restore the facilities and look forward to welcoming you again in spring 2025. Thank you for your understanding and patience.


The caves of Moidons, located in the heart of the Jurassian forest, were discovered in 1966, and were opened to the public in 1989.

 Since April 2013, a new gallery now allows easy access.


One of Mother Nature's masterpieces.

Grandioses stalagmites, colonnes, draperies, innombrables stalactites forment un paysage étincellant de beauté.
Puis viendra le moment d'émotion, les plus belles stalactites du Jura se donnent en spectacle : voici le Son et Lumière !
