Discover Vietnam - Phong Nha cave

Phong Nha-Ke Bang is home to the largest cave in the world and covers 300 different grottoes and caves. Before Son Doong Cave was found, Phong Nha cave was regarded by British Caving Association as the top cave in the world due to its 4 top records:

• The longest underground river,
• The highest and longest cave,
• The broadest and most beautiful fine sand beaches inside the caves
• The most spectacular stalagmites and stalactites.

In the survey conducted in April 2009, the British cave explorers discovered 20 new caves with total length of 56 km, including world’s largest cave Son Doong.
