The Vercors has a rich and varied underground landscape. We invite you to explore underground galleries, giant rooms, millennia old concretions and other underground jewels.

A day full of adventure half way between caving and canyoning:
- Introduction to caving in an underground network.
- Picnic (please bring your own)
- Afternoon “Dry Canyon”, several abseils in a canyon
- For groups, schools or organisations, we offer packaged holidays with our partners: full-board service with indoor accommodation or in a campsite.
