The cave was later introduced to the world by National Geographic Magazine and National Geographic TV.

Son Doong Cave is located in the core zone of Phong Nha - Ke Bang National Park, Quang Binh province, which was recognized by UNESCO as a world natural heritage in 2003 and 2015. The cave was accidentally discovered in 1990 by Mr. Ho Khanh during a routine trip into the jungle. He then contacted the members of the BCRA - British Cave Research Association and led them to explore the cave.

BCRA experts have measured that Son Doong is almost 10km long with sections reaching up to 200m tall and 150m wide, enough space for an entire new york city block complete with 40-story skyscrapers. With a total measured volume of 38.5 million cubic meters, Son Doong surpassed Deer Cave in Malaysia and was officially confirmed as the largest natural cave in the world to date. The ecosystem of Hang Son Doong is as unique as it is large, and it even has its own river and weather. Son Doong has two huge dolines that have created openings, allowing lush forest and rich vegetation to grow inside the cave.

For conservation purposes and to provide the best experience for visitors, Son Doong Expedition only allows up to 1000 visitors per year, and tours are only available from January to August.
