Hang Son Doong is located deeply in the Phong Nha Ke Bang National Park in the central of Vietnam, which was recognized as the world’s largest cave.
Son Doong cave was discovered first by a resident in Quang Binh in 1990. But not until 2009, a new British expedition determined that “ this cave is the largest cave in the world with a height of about 200m, 150m width and approximately 5km long”. In the cave there are a river and a dense forest.
The entrance is quite small and mist from the cave, caused by the cooler air inside meeting the hot air outside, rises into the surrounding forest. Visitors must descend 80m down a steep wall with the use of harnesses and ropes.
The huge temperature difference also creates moving clouds of mist, especially near the two karst windows, which gives the cave its magically surreal atmosphere.
