Grottes d'Osselle
An old cave open to visitors since the 16th century, featuring coloured stalactites and a complete cave bear skeleton.
The cave lies in the Doubs valley and is said to have welcomed visitors since 1504, making it one of the earliest show caves in Europe. The guided route is about 1.3 km long. Stalactites display white, red and yellow hues caused by minerals, and unearthed cave bear skeletons are on display. A guided visit takes about an hour, admission costs about €10, and it is seasonal. The cave stays around 13°C. It is about 20 km southwest of Besançon and can be visited on the way to Arc-et-Senans.
