About Tien Ong Cave

Intricate stalactites and stalagmites inside Tien Ong Cave.

The most captivating features of these caves are the stalactites and stalagmites that are formed by a slow process of mineral deposition. Water, dripping from the cave ceiling, dissolves minerals like calcite and redeposits them, creating these magnificent formations over thousands of years. These cliff formations stand as testaments to the exquisite craftsmanship of nature. In this subterranean world, time moves entirely in a different dimension. It is measured not in days or years, but in the slow and gradual deposit of the mineral layer and its accumulation. Each stalactite and stalagmite exhibit are witness to this timeless process in the ever-evolving tapestry of our planet’s geological story.

Founded in 1938 by J.G. Anderson, a Swedish archaeologist, Tien Ong Cave is in Cai Tai Island of Ha Long Bay. Halong Bay Management opened these caves in 2007 for tourism with the collaboration of the Vietnam Historical Museum. Also called the God Cave or the Fairy Cave, these caves stretch up to 20 km to the south of Ha Long City and around 7 km approximately from the island of Cat Ba. With a wide entrance, the cave floor is almost about 5m above sea level. These caves about 1000 m2 wide have quite sloppy insides. The stalagmites have dropped from the top of these caves and grew from the bottom creating a wall-like obstruction dividing the cave into two. The archaeological findings also show traces of ancient human habitation in the caves as old as 10,000 BC to 8000 BC.
