Tien Son Cave, often overshadowed by its famous neighbor Phong Nha Cave, is a stunning dry cave located in the heart of Phong Nha-Ke Bang National Park.

Nestled within Vietnam’s lush jungle, Tien Son Cave presents a surreal underground world full of geological wonders.

Geological Marvels

Stunning rock formations inside Tien Son Cave in Phong Nha National Park

As you step inside Tien Son Cave, you’ll be greeted by the sight of massive stalactites and stalagmites, some resembling famous landmarks or mythical creatures. Formed over tens of millions of years, these rock formations have been shaped by natural forces, creating a mesmerizing underground landscape. Stalactites and stalagmites of varying shapes and sizes adorn the cave, and when struck, some formations emit sounds that resemble drums or gongs.

A Journey Through History

Visitors can walk about 400 meters into the cave before reaching a 10-meter deep abyss, beyond which the cave becomes more dangerous and is reserved for professional expeditions. Scientists from the British Royal Cave Association (BCRA) believe that Tien Son Cave formed when an ancient river eroded the limestone, creating the underground passages we see today. Interestingly, the cave predates Phong Nha Cave and was carved out during a different geological era.

The ceiling of the cave glitters with gold and silver-like veins, and some rock formations are said to resemble heavenly palaces. Visitors can feel the mystery and ancient charm of the cave, enhanced by local legends that speak of fairies and brave heroes who once roamed these chambers.
