Son Doong Cave is the world’s largest cave located in Son Trach, Bo Trach District, Quang Binh Province. The cave was found by a local man named Ho Khanh in 1991 and explored by Bristish cavers in 2009. It is considered as the world’s largest cave, one of the most beautiful caves, highest and deepest cave.

The National Geographic estimate the height of Son Doong Cave: “The passage is perhaps 300 feet wide, the ceiling nearly 800 feet tall: room enough for an entire New York City block of 40-story buildings.” The beauty and epic of Son Doong is no word to explain. And it is also an actual challenge for explorers.

Featured with magnificent stalactite collection, attractive “cave pearls”, broad river flowing along the cave and one-of-a-kind green forest inside the cave, Son Doong is incredibly spectacular wonder of nature. Let’s take a look amazing pictures taken by international photographers and cavers to feel this natural treasure.

The entrance gate is quite small and has mist inside caused by cooler air inside meeting the hot air outside. From this gate, you will feel a totally different atmosphere with decreasing temperature and a surreal space.

Amazing size of the cave. You have to use rope and harness to explore huge rocky and limestone mountains in the cave.

Inside Son Doong Cave is a huge river which its source is unknown.

The cave is shined by sun because of the holes on top. Therefore, there is a jungle inside the cave which is called “garden of Edam”. The jungle has a very diverse ecosystem, including precious plants, animals and birds.

Thousands of “cave pearls” lie untouched in Son Doong. This unique natural phenomenon are formed over hundreds of years when dripping water creates layers of calcite that build up around grains of sand.
