Top 4 Caves フェイ・エン・モンターニュでの

A small but great cave - flashlight recommended.

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.

The Hole of the Moon is a cave dug in the limestone rock of the cliffs overlooking Poligny and its vineyards.

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.

Great experience! Flashlight indispensable.

With a length of almost 16 km, this active water cave is the largest in the whole of the Jura department. The cave is locked and only accessible to organized speleologists. After long rainfalls or snowmelt, the cave in the entrance area is often overcrowded so that if the weather conditions are disregarded, you can be locked in this grotto.

A small cave where a lot of prehistoric has been excavated and that very late.
