Visit the Grotte de Choranche, a natural treasure in Isère. Book your gîte, bed and breakfast or holiday rental with Clévacances for a memorable stay close to this geological wonder.

Nestled in the heart of the Vercors Regional Nature Park in Isère, the Grotte de Choranche is one of France's most fascinating natural wonders. This underground cavern is famous for its unique geological formations and subterranean landscapes, which attract visitors from all over the world. For those looking for comfortable and convenient accommodation, choosing a holiday rental, gîte or chambre d'hôtes with Clévacances ensures an unforgettable experience close to this outstanding natural attraction.
The Grotte de Choranche is notable for its vast chambers decorated with stalactites and stalagmites as well as its rare fistuleuses, concretions so fine they are comparable to angel hair. Discovered in the 19th century, it has now been fitted out for a comfortable and safe visit, offering subtle lighting that highlights its limestone formations and clear water pools.


The Grotte de Choranche is renowned for its exceptional geological features, making it a must-visit for caving enthusiasts and nature lovers alike. One of its most remarkable features is the presence of extremely rare and delicate stalactites known as "fistuleuses" or "macaronis", which hang from the ceiling of the cave like angel hair. These impressively fine formations are made of pure calcite and can be several metres long, yet only a few millimetres thick.
The cave's vast halls and underground galleries are also the setting for a natural spectacle made up of pools of crystal-clear water. These water mirrors, fed by continuous seepage, reflect the surrounding limestone formations and create an enchanting play of light when illuminated during the guided tour. The constant temperature and high humidity inside the cave also encourage the development of a special ecosystem, home to species adapted to life in the dark, such as the famous protoea, a blind, translucent amphibian.
Each guided tour of Grotte de Choranche is an educational adventure where you discover the geology, biology and history of this place. Guides explain the formation of the caves, the unique ecosystem that thrives there, including rare species such as the protaeus, a blind amphibian adapting to total darkness. Information panels and multimedia presentations enhance the tour, making it accessible and captivating for all ages.

Visiting the Grotte de Choranche is an enriching experience that offers a plunge into an underground world of beauty and mystery.
