Trou qui souffle, Natural cave in Autrans-Méaudre-en-Vercors, France
The cave system extends through approximately 50 kilometers of passages with five different entrances spread across the mountainous Vercors region.
Discovered in 1936, the cave provided ice to coffee merchants in Grenoble during earlier times, supporting the local agricultural economy.
The Drabons et Chieures de Méaudre association hosts regular exploration events that connect visitors with the underground network of passages.
Visitors can access the cave by following Route des Feuilles in Méaudre, located one kilometer from the village center.
Two rock cracks at the entrance release cold air continuously, creating a natural ventilation system throughout the extensive underground network.
