Where is the deepest cave on Earth?

The deepest explored cave on Earth is Veryovkina Cave, located in the Arabika Massif of Abkhazia, a region of Georgia in the Caucasus Mountains. Explorers have mapped it to a depth of around 2,212 metres, making it the first known cave to exceed two kilometres deep. Nearby lies Krubera Cave, also in the same massif, which held the record for many years and reaches a comparable depth. Descending such caves is an extreme and dangerous undertaking, requiring expeditions that last weeks, camp underground, and navigate flooded passages, vertical shafts, and narrow squeezes. Scientists study these deep systems to learn about geology, groundwater, and life forms adapted to permanent darkness. New surveys occasionally shift the exact depth rankings as exploration continues.
