The majesty of Son Doong cave

Son Doong cave is located in Phong Nha-Ke Bang. It is part of the underground system connecting more than 150 other caves in Vietnam located near the border with Laos.

The cave is 200 meters wide, 150 meters high, at least 6.5 kilometers long. The length may be even deeper, but due to limited technical conditions, the explorers of the Royal Caves Association can not go all the way to the depths of the cave to determine how long the cave is.

At this size, the Son Doong cave crossed the Deer Cave in Malaysia’s Gunung Mulu National Park (100m high, 90m wide, 2km long) to occupy the largest natural cave in the world.

In addition, some sections of the Son Doong cave have a large size of 140 m x 140 m, including stoneware columns up to 14m high. A splendid photo taken by photographer Carsten Peter in May 2010 recorded a cave section measuring 91.44 m wide, with a cavern height of nearly 243.84 m – could contain a 40-storey building of New York City.

In the cave, the researchers found a 2.5km-long underground river and 70 meters of stalactites.
