The Sơn Đoòng and Thien Đuong caves might have hogged the international spotlight, but other caves are equally spectacular options for visitors to Việt Nam.
Phong Nha-Ke Bang National Park in Quang Binh Province is frequently referred to as the ‘Kingdom of Caves’ for the magnificent specimens it boasts.
Its profile soared worldwide when the largest and most spectacular cave of them all, Sơn Đoòng, was covered by the likes of National Geographic, CNN and Business Insider.
Since then, many famous travel magazines have used this name to refer to the central province of Quang Binh.
Le Thanh Tinh, director of Phong Nha-Ke Bang National Park, said more than 350 caves have been discovered in the park over the last 25 years, of which 30 have become tourist attractions.
Besides Sơn Đoòng, other well-known caves include Én and Pygmy, which are said to be the third and fourth biggest in the world.
