A Rich History

Discovered in the 13th century and adapted for visits from the start of the 16th century, the Osselle Cave is considered to be one of the oldest tourist caves in the world. It is also famous for being one of the largest cemeteries for cave bears and around 2,000 to 3,000 bear skeletons were found during the first excavations in 1826. These plantigrade mammals could grow up to 2.50 m in height. The cave was even a place of celebration for Voltaire and the region’s public figures, who organised banquets and parties there, among the mineral splendour found in the tunnels.

 

Exceptional Nature

This site exudes natural beauty. At the heart of this cave you can find many types of crystallisations and impressive colours, ranging from green to red, through to black, white and orange. The stalactites, stalagmites and other geological wonders are no less magnificent, and offer visitors a gentle introduction to caving and the underground world. They will also have the opportunity to discover local wildlife and plant.

 

An Ideal Layout

Over 1,300 metres of the cave have been adapted for visitors, who can go deep into this historically and naturally breath-taking place, which extends underground from Doubs to the Jura. Accessible to both children and adults, the visit lasts a little over an hour, and uses flat, safe paths for everybody’s comfort.
