A UNESCO World Heritage Site


Unveiling the geology and history of Ha Long Bay is like turning the pages of a fascinating natural history book. Recognized twice as a UNESCO World Heritage Site for its outstanding geological and geomorphological value, Ha Long Bay possesses a significant place in the world's natural heritage. Shaped over 500 million years, its awe-inspiring landscapes are a testament to the power of nature and time.


Ha Long Bay, also known as "Descending Dragon Bay," spreads across 1,553 km² and houses approximately 1,600 limestone islands and islets. This majestic seascape took over 500 million years to form, with each karst and islet narrating its own tale of geological evolution through the prehistoric periods.


The bay's karst landscape is a result of a complex chain of geological, climatic, and sea level changes. Over millions of years, the region underwent significant shifts from a shallow sea area to a Quaternary continental environment, resulting in a feast of geo-diversity including ancient marine sediments, marine, continental, and terrestrial organic forms.

The limestone karstic landforms in Ha Long Bay have evolved through the process of weathering and gradual erosion, developing a mature tropical karstic landscape that is unique and richly diverse in form, such as phytokarst (karst area covered with vegetation), karren fields, dolines, and towers.


It was this distinctive landscape and the aesthetic beauty it encapsulated that led to Ha Long Bay being recognized as a UNESCO World Heritage Site in 1994. The site was selected under Natural Criterion VII as it represents a globally outstanding aesthetic value recognized in the scenic beauty of its towers, islands, and enclosed bays.


In 2000, the site was again inscribed by UNESCO, this time under Criterion VIII, recognizing its outstanding geological and geomorphological value. The twice recognition by UNESCO not only affirmed the universal value of Ha Long Bay but also the commitment to preserve this remarkable site for future generations.


These extraordinary landscapes, combined with the rich biodiversity and cultural heritage, make Ha Long Bay an invaluable treasure trove, capturing the world's imagination and inviting all to explore its splendors. Each visitor leaves with a deeper appreciation of the power of nature, the beauty of biodiversity, and the timeless history etched in every nook and cranny of this bay.

Each formation carries its tale of geological evolution, further adding to the bay's charm.


Sung Sot Cave (Surprise Cave)

One of the largest and most renowned caves in Ha Long Bay, Sung Sot Cave, often amazes visitors with its grandeur. The cave comprises two chambers. The first one, often perceived as a theater, opens up to a larger chamber that boasts an array of stalactites and stalagmites, brilliantly illuminated to showcase their beauty. What's surprising is the constant cool temperature inside, a pleasant retreat from the tropical climate outside.


Dau Go Cave (Wooden Stakes Cave):

Dau Go Cave is another impressive site with a historical anecdote. It's said that this cave was the spot where General Tran Hung Dao hid wooden stakes to use against the invading Mongol fleet in the 13th century. Inside the cave, you'll discover a stunning assortment of stalactites and stalagmites, some of which resemble human figures and mythical creatures, sparking your imagination.


Floating Villages

Another key attraction that sets Ha Long Bay apart is its floating villages, primarily Cua Van and Vung Vieng. These are fully functional, water-based communities, complete with schools and markets. The villagers, mostly fishermen, live in quaint floating houses and move around in small boats. A visit to these villages provides a unique cultural insight into their lifestyle, showing how they've adapted to life on the water and lived in harmony with the sea for generations.
