In 1991 Hồ-Khanh, a farmer stumbled across a previously unexplored cave in Phon Nha-Ke Bang national park, Vietnam. He was frightened by the terrible roar of water emanated from the entrance, and he decided not to go inside. The local people named it Son Doong, but none of them dared to explore the cave.
It was only in 2009 that a group of British scientists led by Howard Limbert, located the cave and decided to go inside. To their surprise, they found a different world ─ a totally self-contained world. The area was 5 kilometres long and 150 metres wide. After the discovery, they came to know that the Son Doong is, in fact, the third largest cave on the planet.
This interesting place has its own flora and fauna, lakes and and you can even see clouds. Let's take a look of this incredible new world.
There are small, emerald-coloured lakes, and even beaches.
The cave contains a wealth of ancient fossils and stalactites.
There are stalactites which are up to 70 metres tall and are considered to be tallest known stalagmites.
Ancient fossils and stalactites are aplenty inside the cave.
There is a jungle inside the cave and has trees that are 3 meter thick. Various different kinds of animals inhabit the cave, including monkeys, hornbill birds, and bats.
The cave even has its own unique climatic conditions.
Clouds form there due to a sharp difference in temperature with the outside world.
This cave is also known as ‘Mountain River Cave’. This cave is a solutional cave because it is formed in the soluble rock known as ‘limestone’.
The cave runs for approximately 9 kilometers.
In early August 2013, the first tourist group explored the cave on a guided tour at a cost of US$3,000 each.
