Le Trou qui Souffle is a vast network of underground cavities and a natural curiosity located in the commune of Autrans-Méaudre en Vercors, in the Isère region. The main entrance was discovered in 1909 during road works, then explored subsequently. Its resurgence is found further down at the Pont de la Goule Noire in the Gorges de la Bourne. It is the second longest network in the Vercors massif, with nearly 50 kilometers of explored galleries and an elevation difference of 670 meters.

La Glacière is a 14 m deep cave. It is the result of the dissolution and erosion of limestone by the long work of water. In the 1700s, landmarks bear witness to the presence of men who came here to exploit the ice. The latter will engrave various inscriptions on the wall. But it was at the beginning of the 20th century that this cave was mainly exploited. Indeed, the ice extracted using a sled is used by cafeterias in Grenoble and hospitals. In 1964, the cooler was 4 m thick, today it is endangered. The rockslides made access to the cooler dangerous and it was closed to the public in 1999.
