An exceptional natural place in the heart of the Vercors

Discover the cavern of Choranche in Isère. During about one hour, you will follow your guide on a pathway, where galleries will light up at your walking pace. Fistulous stalactites, ‘straws’ of calcium carbonate, overhang underground lakes and rivers, and rooms of more than 30 meters diameter et 15 meters height create wonderful perspectives. You will catch sight of olms, some curious creatures. Finaly, along the Serpentine river, you will join the majestic Cathedral room to enjoy an amazing Son&lumière.
