World's deepest cave | Krubera-Voronya Cave

Documentary footage of 3 Lithuanian speleologists (Saulė Pankienė, Gintautas Švedas, Aidas Gudaitis) and 1 cave diver (Vytis Vilkas) diving through "Kvitochka" siphon and getting to siphon "Dva Kapitana" in Krubera Voronya cave, 2010 August. Dive through siphon takes about 4 minutes, but it's cropped as it's not very informative due to poor visibility.

Located in the Republic of Abkhazia, the Voronya Cave (Crows’ Cave, in Russian) plunges 7,188 feet (2,191 m) into the depths of the Arabika Massif, a limestone formation dating back to the Age of Dinosaurs. Also known as the Krubera cave (after Russian geographer Alexander Kruber), the cave was discovered in 1960 and has surpassed Austria’s Lamprechtsofen as the world’s deepest cave and the only known cave deeper than 2,000 meters (6,561.5 ft).
