    Rock climbing

    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.

    Rock climbing

    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.

    Hiking

    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.
