Magnificent and impressive natural cavity that can be explored with a lamp. At the bottom there are beautiful ice formations even in summer. This phenomenon is due to the shrinkage of the cavity which traps cold air at the bottom. When moisture seeps through the ceiling, the temperature is low enough for the water to freeze and form stalactites.

You have to go take a look before or after visiting the Choranche cave. It's not far at all and the trail is accessible even to children. The cave is easily visible (staying outside) without specific equipment. You can then go see the waterfall.

This underground landscape once invaded by water is now punctuated by rock sculptures with natural pigments. Through objects found in this millennial cave, we relive the daily life of Homo Sapiens. During the visit, the guide illustrates the formation of this cavity and its occupation during the last ice age. More info here: https://www.visites-nature-vercors.com/fr/grotte-de-thais/decouvrir/

Parking and map displayed. Departure on a very pleasant and marked path. Magnificent view and several impressive and accessible hollow "coolers" which are indicated (10 points to be indicated on the map and trail). I was able to see the 1st nearby as I broke my toe before...next time for the rest. Thought of a lamp, it's better inside dark, in the first you can cross and come out on the other side...
