Cave diving is an underwater activity that involves exploring submerged caves using specialized diving equipment. Divers must be trained and certified due to the unique challenges posed by limited visibility, strong currents, and the potential for getting lost in complex cave systems. Safety protocols, such as using multiple air tanks and dive teams, are essential. This sport combines elements of scuba diving and spelunking, allowing divers to experience stunning underwater formations like stalactites and stalagmites. Popular locations for cave diving include the Blue Hole in Belize and the Cenotes in Mexico, which attract divers from around the world seeking adventure and exploration.
