The Bay is recognized as a UNESCO World Heritage Site twice and a very popular tourist destination in the northeast part of Vietnam, under the management of both Quang Ninh and Hai Phong provinces.

The whole bay has an area of around 1,500km2, which contains approximately 1,969 islands and islets made from karst and limestone towers.

A long history and tremendous values lie within these magnificent limestone mountains. 

Normal limestone mountains are usually found on the ground, however, the the Bay’s limestones are raised from above the water.

It’s taken 500 million years to form Halong Bay to 2000 limestone islands as today.

Human beings have inhabited the area for centuries but made no damage to the heritage. The appearance, indeed, added unique cultural values to Ha Long Bay.
