Son Doong cave belongs to Phong Nha - Ke Bang cave complex, located in Son Trach commune, Bo Trach district, Quang Binh province, Vietnam. According to geologists, Son Doong cave was formed about 2 - 5 million years ago with an estimated length of at least 6.5 km, 200 m high, 150 m wide.
With the above size, Son Doong cave surpassed the world record of Deer cave in Gunnung Mulu National Park (Malaysia), becoming the largest, most majestic and splendid natural cave in the world.

Son Doong formed on a fault in the Truong Son range and was eroded by the Rao Thuong river over millions of years, forming a giant tunnel beneath the limestone mountains. Cracks in the ceiling of the cave were corroded and subsided, forming large sinkholes that opened to the outside. Inside that magnificent space is a separate world, a rare natural wonder that surprised the conquerors of Son Doong.
