Dive-site story
Source de la Douix is a celebrated karst resurgence emerging at the foot of a limestone cliff in Châtillon-sur-Seine. Revered since Celtic and Gallo-Roman antiquity, this natural spring opens directly into an expansive flooded cave network. Diving here is strictly an overhead cave exploration requiring specialized training, guideline protocols, and redundant gas management to navigate the subterranean conduits and sumps.
