Gouffre de Poudrey
Discover the Gouffre de Poudrey differently.
A dive into the bowels of the earth.
A geological phenomenon, the Gouffre de Poudrey takes you 70 metres underground into a cave of colossal dimensions: it could contain the entire Notre-Dame de Paris. It is currently one of the largest underground chambers in France. As you walk, you will discover surprising, magical architecture, shaped by the combined talents of water and time.
Stalactites and stalagmites and other limestone concretions form a real city of darkness.
A new guided tour concept using the latest technology has been introduced in 2023. Professor Fournier, who organised the first descent into the chasm in 1899, will guide visitors along the route in 5 languages using the latest equipment (smartphone + semi-open headphones). Enhanced by a new lighting system that emphasizes this grandiose setting, a dramatized visit, musical atmospheres and the show “Music and Lights”, the Poudrey gorge is seen in a new light.
Exhibitions on karst, water and the consciousness of bats extend the visit.
