How was Hang Son Doong formed? Son Doong Cave has the largest cave passage in the world located in Phong Nha – Ke Bang National Park, Quang Binh, Vietnam. While Phong Nha – Ke Bang National Park is one of the oldest system of limestone mountain in Asia with around 400 million years old, Hang Son Doong was only explored in 2009 and is less than 3 million years old. Two large rivers, Khe Ry and Rao Thuong, joined together to form Son Doong Cave millions of years ago, creating a huge passage beneath the limestone mountains.

This enables the unusual formations like Phytokarst to develop, and also plants and trees to grow inside the cave.
