Meet the EVEREST of Caves
With a total length of cave passages reaching a staggering 13,232 m, the deepest explored parts of Krubera-Voronya reach 2,197 m. It remains the only known cave on Earth deeper than 2,000 meters—rightfully earning the title as the entrance to Inner Earth.
Discovered in 1963 by a team of Georgian speleologists, it was called the Krubera cave. At that time, they explored it only to the depth of 57 meters. In 1970, the cave was again explored and called Siberian.
In the middle of 1980, the cave had a third expedition, receiving the name of Voronya. Today, the cave is known in the region as Krubera-Voronya. The cave has only one entrance and it is known that there is an underground river flowing through it that drains into the Black Sea.
In 2001, Krubera-Voronya was recognized as the world's deepest natural cave, when a team of speleologists from the Ukrainian Speleology Association explored it to a depth of 1,710 meters. Over the years, ever greater depths have been achieved. In 2004, the Association reached a depth of 2,080 meters; In 2007, to the depth of 2,191 meters and in 2012, to the depth of 2,196 meters, the largest ever achieved.
