Phong Nha Cave

Formed approximately 250 million years ago, Phong Nha Cave is the largest and most beautiful famous cave in Vietnam. Situated in the village of Son Trach, it was designated a Unesco World Heritage site in 2000. As a cave in Phong Nha - Ke Bang National Park, it’s remarkable for its thousands of metres of underground passageways and river caves filled with abundant stalactites and stalagmites. In November and December, the river is prone to flooding’; the underground cave may be closed, though it’s possible – but also may be dangerous – to visit the dry caves.

Phong Nha means “Cave of Teeth, even though the “teeth” exists no more by the entrance. Once you get further into the cave, it’s mostly unspoiled. There’s also a dry cave in the mountainside just above Phong Nha Cave.
