The grotto is currently not open! A fire completely destroyed the visitor center this spring. It is not yet known when the grotto will be open to visitors again. https://www.grottesdesmoidons.com/en/useful-information.htm

After years of bans or restricted access, the Jura Departmental Speleology Committee reached an agreement with the municipality of Nevy-sur-Seille, and is now tenant of the cavity. The rental lease requires that the entrance be closed by an armored door, and its access reserved for clubs and individual members of the French Speleology Federation, or a foreign federation. Before any visit, to obtain the access code, you must submit a request to the C.D.S du Jura. (http://juraspeleo.ffspeleo.fr/grottes/topoguide/fiches/cassots.htm)

This small cavity has the ceiling pierced at the beginning and at the end of the gallery. It would have sheltered a hermit.

A good 16 km of underground passages and galleries. A beautiful stream, very rich in stalactite jewelry, but also very dangerous during melting snow or long rainy days. As a result, the cave is also closed and access is only for organized cave exploration accessible.
