Gouffre de Poudrey

The underground chamber extends 70 meters deep and contains numerous limestone formations, including stalactites and stalagmites throughout its million cubic meters volume.

Professor Fournier conducted the first documented exploration of the cave system in 1899, establishing the foundation for future geological studies and public access.

The cave offers educational programs about karst landscapes and water conservation, while presenting geological exhibitions that demonstrate natural formation processes.

Tours operate Wednesday through Sunday with admission prices of 10.50 euros for adults and 8.50 euros for children between 5 and 14 years old.

The central chamber contains enough space to fit the entire Notre-Dame de Paris cathedral and features a subterranean lake stretching twelve meters in length.
