Grotte Chevalier and Annette Discovery

The Grotte Chevalier is 800 metres long, 40 metres wide and as wide under the ceiling. Littered with boulders, it is easy to walk through to its end, 160 metres below the entrance. The Grotte Chevalier is a major underground walk, where you can progress without the need for ropes, in the interior and silent immensity of the mountain. It’s sure to delight all those who want to discover the underground world, including children aged 10 and over, for whom this day’s adventure will be unforgettable.
The Grotte Annette is an astonishing discovery outing. It takes you through a series of very old, comfortable and sometimes richly concretioned galleries, all without the need for ropes. Some passages will require skill and flexibility, but the arrival at the bottom of the Puits de la Gnôle will reward visitors for all their efforts. This incursion into the heart of the Dent de Crolles will delight all those who want to discover the underground world, including children aged 10 and over, for whom this day’s adventure will undoubtedly be unforgettable.
