In the heart of the Vercors, explore these caves hidden among the weird and wonderful natural formations of the Cirque de Choranche… and enter a magical world. Escape to a place where time stands still; you'll be amazed by what you'll see on this underground boat trip. Emerald reflections from the subterranean lakes and rivers dance all over the long, slender crystal-white stalagmites and stalactites: this is Nature in its purest form. On your trip you'll catch sight of a cave-dwelling animal that has survived from the age of the dinosaurs: the bizarre olm. Then an amazing sound and light show awaits you in the gigantic Cathedral Hall: "the Cavern of Time". Your imagination will run wild, inspired by the myths and mysteries of this underground world.
