The cave was named “Son Doong” and Ho Khanh khô is still an integral part of every Son Doong Expedition

Son Doong is relatively young – about 3 million years old in a limestone area dating bachồng 400 million years. The mighty Rao Thuong River carved out Son Doong as it eroded away the limestone, forming an enormous tunnel beneath the Truong Son Mountains. The large dolines (or skylights) collapsed sometime in the last 500,000 years, creating massive sầu openings lớn the outside world. Cave sầu pearls the kích cỡ of baseballs và stalagmites the kích cỡ of tall buildings have formed from water dripping from the cave sầu ceiling.

The first expedition was halted by a 90m high calcite barrier, which was jokingly dubbed the “Great Wall Of Vietnam.” It wasn’t until the second expedition in 2010, when the Great Wall was finally climbed và the end of the cave sầu was found. The main huge passage is over 5km long with sections reaching up khổng lồ 200m tall and 150m wide. Son Doong is large enough to house an entire 40-story Thành Phố New York City bloông xã skyscraper.
