Son Doong cave - One-of-a-kind natural wonder in the world

Son Doong cave was certified by the Guinness World Records, World Records Association as the most extensive cave globally, with 150 meters by width, 200 meters by height, and up to 9 kilometers by length. Son Doong cave is nestled in Phong Nha - Ke Bang National Park - the largest national park in Vietnam covering an area of around 1,233km2 (~304k acres) . Phong Nha - Ke Bang is dubbed as ‘cave kingdom’, as besides over 350 caves were discovered, here not only you can find the world’s largest cave but also the world’s 3rd largest cave - En. One can check in both caves in one trek expedition when En cave is chosen to be the first checkpoint on the first day of the 4-day Son Doong trek. 

Known as “the king of caves”, Mr. Howard Limbert - one of the very first BCRA members that discovered Son Doong cave in 2009 - stated: “I was fortunate to have explored 700 caves throughout Vietnam,  and 350 of them are in Quang Binh. And it’s really something to discover the largest cave in the world only in this 21st century. Imagine you found a taller mountain than Everest. [..] I believe Son Doong is unique and not yet fully studied. Big caves have clouds in large chambers but have jungles in the cave and their own weather system -  I think Son Doong is pretty unique. There are new species to be discovered by scientists... We hope in the near future to bring experts on plants and bats to study as there is still a lot of work to be done. The final underwater section is still to be completed.”

To explore and witness this majestic world’s natural wonder, ‘explorers’ will experience a combination of adventure sports in one expedition, such as forest trekking, stream wadding, hiking, and even kayaking during the rainy season... which requires some reasonable physical strength and trekking experience. In the past 5 years, Son Doong cave has welcomed 3,500 visitors to explore the cave; Oxalis Adventure - the sole Son Doong expedition tour revealed.

People of Quang Binh and myself are proud to see Son Doong featured on Google’s homepage to acknowledge its beauty and value and introduce it to the world. Thanks to the development of the tourism and conservation plan of Son Doong within  Phong Nha - Ke Bang National Park, it has created many job opportunities for the local people, contributed to economic restructure, improved the quality of life here and located Phong Nha- Ke Bang on world travelers’ maps.” Mr. Ho An Phong - Vice Chairman of Quang Binh Provincial People's Committee
