Martinet

Martinet is an advanced cave diving site in the Midi-Pyrénées of France, part of the extraordinary network of karst siphons that make this region a mecca for speleological divers. The underground passages at Martinet penetrate deep into the limestone bedrock, requiring experienced cave divers with full technical equipment and redundant life support systems. The spring water provides the excellent visibility for which the region's cave dives are celebrated. The cave's geological features may include flowstone formations, stalactites, and passage restrictions that add technical complexity. The consistently cool underground temperatures demand thorough thermal planning for extended penetrations into this Pyrenean cave system.
