Hang Son Doong, the world's largest cave
Become one of the lucky few who have had the life changing experience of exploring the world’s largest cave. It is located in the heart of the Phong Nha Ke Bang National Park, in Central Vietnam. Discovered in 2009, "The Mountain River Cave" has only been open to the public since 2013.
At over 5km long, with sections reaching up to 200m tall and 150m wide, Hang Son Doong is large enough to fit entire 40-story skyscraper within its walls! It even has a jungle, river and its own localised weather system with misty clouds and cool wind. Discover foreign landscapes with stalagmites up to 80m high - the tallest ever encountered!
