Office de Tourisme des Coteaux du Jura

The caves at Baume les Messieurs, a site listed among the most beautiful villages in France, are situated on the side of one of three blind-valleys that were formed over 200 million years ago. Up to 120 metres underground, the caves offer a 600 metre-long itinerary through galleries and chambers some of which are 80 metre-high.
During the tour you can see strange stalactites, stalagmites, rivers and underground lakes, all of which are made magical by special lighting and a musical background. These caves are also home to bats and blind shrimps.
