Gouffre de Poudrey
Said to be the largest open-to-the-public underground chamber in France, with a light and sound show featuring stalactites and stalagmites.
The cave is a huge chamber formed by karst collapse, about 200 metres long and 70 metres high. Visitors descend staircases to the floor of the chamber while lighting and music accompany the viewing of stalagmites and stalactites. A guided tour lasts about 45 minutes and admission costs about €10. It is seasonal, and the cave is cold, so bring a jacket. Located near Étalans, about 25 km from Besançon, it can be combined with the Loue valley sites on a self-drive trip.
