Combe Négre

Combe Nègre is an advanced cave diving site in the Midi-Pyrénées of France, where a dark limestone gorge conceals the entrance to an underground siphon system. The name, meaning 'black valley', aptly describes the shadowy approach to this challenging cave dive. The siphon passages penetrate deep into the karst bedrock, with the clear groundwater revealing beautifully eroded limestone walls and formations. Technical demands include cold water management, precise navigation through complex gallery systems, and strict gas planning. The remote, wild setting of Combe Nègre adds to the sense of adventure that draws elite cave divers to the Midi-Pyrénées region.
