The Sassenage caves are located in the department of Isère, at the foot of the Vercors massif, in the commune of Sassenage, in the Grenoble urban area.

In the middle of a preserved fauna and flora, the cave Les Cuves de Sassenage, classified as a natural heritage site, invites you to contemplate the clear waters of the Furon and an exceptional panorama of Grenoble. A guaranteed change of scenery, in the heart of the Vercors regional nature park, making you forget for a moment the proximity of the urban area...

The site is partially open to the public (except in the winter months), its entrance is not free and is subject to climatic risks due to the risk of flooding.

Presenting a preserved fauna and flora, the Sassenage caves are classified as natural heritage and allow you to contemplate the clear waters of the Furon while taking advantage of the proximity of a large urban area. This place appears to be a medium development cave measuring about a dozen kilometres in length.

The part open to visitors allows you to discover the "large vestibule" marking the junction between the two entrances. A torrent flows through this part and flows to a lower level thanks to a beautiful waterfall that benefits from a beautiful downward lighting by the part called "Square Cave". The interior consists of modest galleries, crossed during certain periods by a torrent and ending in a beautiful underground space called "salle Saint-Bruno".
