Situated in the North-East region of Vietnam, Halong Bay is a bay in the Gulf of Tonkin comprised of regions of Halong City.

Halong Bay is made up of 1,969 islands of various sizes, 989 of which have been given names. There are two kinds of islands, limestone and schist, which are concentrated in two main zones: the southeast (belonging to Bai Tu Long Bay), and the southwest (belonging to Halong Bay). This densely concentrated zone of stone islands, world famous for its spectacular scenery of grottoes and caves, forms the central zone of Halong Bay, which has been named a UNESCO World Heritage Site.

Viewed from above, Halong Bay resbbles a geographic work of art. While exploring the bay, you feel lost in a legendary world of stone islands. There is Man's Head Island, which resbbles a man standing and looking towards the mainland. Dragon Island looks like a dragon hovering above the turquoise water. La Vong Island resbbles an old man fishing. There are also the islands of the Sail, the Pair of Roosters, and the Incense Burner, which all astonishingly resbble their namesakes. The forms of the islands change depending on the angle of the light and from where the islands are viewed. At the core of the islands, there are wonderful caves and grottoes, such as Thien Cung (Heavenly Residence Grotto), Dau Go (Driftwood Grotto), Sung Sot (Surprise Grotto), and Tam Cung (Three Palace Grotto).

The 18th meeting of the Committee of the World Heritages of UNESCO (in Thailand on Decbber 17th, 1994), officially recognised Halong Bay as a natural heritage site of world-wide importance.
