Grotte Célestine is a natural subterranean cave system located in the village of Rauzan in the Gironde department of France. The site is characterized by an underground river that visitors navigate via a purpose-built walkway. Discovered in 1845, the cave features significant limestone formations, including stalactites and stalagmites. The subterranean environment maintains a constant year-round temperature, contrasting with the surface climate. Access to the cave is strictly regulated through guided tours to preserve the fragile geological environment. The site is a primary example of karst topography in the Entre-deux-Mers region.
