Halong Bay is one of the world's natural wonders and is the most beautiful tourist destination of Vietnam. Halong Bay features more than one thousand awesome limestone karsts and islands of various sizes and shapes along the 120-km coastline of Bai Chay Beach.
Its waters are host to a great ersity of ecosystems including offshore coral reefs, freshwater swamp forests, mangrove forests, small freshwater lakes, and sandy beaches. The folk tale has it that the dragons descended from heaven to help locals by spitting jewels and jade to the sea, forming a natural fortress against invaders; these precious stones are represented by the lush green outcrops. Several islands boast beautiful grottos and caves with contiguous chambers, hidden ponds and peculiar stone formations. The bay is about 170 kilometers northeast of Hanoi and 3,5 hours by road.
“Ha Long” is literally translated as "Bay of Descending Dragons." Prior to the 19th century, this name was not recorded in any document or archive. When mentioning the present-day Quang Ninh Sea or Ha Long Bay, old historical books often referred to them by the names of An Bang, Luc Thuy or Van Don.
Not until the late 19th century did the name of Halong Bay appear on a French Marine Map. “The Hai Phong News”, a French newspaper of the time, had an article, “Dragon appears on Ha Long Bay”, reporting the following story: In 1898 a sub-lieutenant named Lagredin, captaining the ‘Avalanse’ reported seeing a huge sea snake on Ha Long Bay. This was also witnessed by many of the crews. Thus emerged the European image of the Asian dragon. Whether this appearance of a strange animal looking like a dragon resulted the name of Ha Long Bay is not known (Reference “Quang Ninh: Art and Culture” published in 2002).
There is also a local legend, which has been handed down, relating to the name Ha Long Bay, which tells the following tale:
“Long ago, in the first founding days, the Viet people were attacked by foreign aggressors. The Jade Emperor sent the Mother Dragon and her band of Child Dragons to help the Viet people fight the invaders. While the enemy vessels were launching massive attacks against the mainland, the dragons descended in flocks from the sky. They spat out innumerable pearls which changed into jade stone islands the moment they touched the water. These islands linked together to form firm citadels that checked the enemy’s advance and smashed their vessels to pieces.
After the invaders were driven out, Mother Dragon and her Child Dragons did not return to Heaven but stayed on earth, right at the place where the battle occurred. The spot where the Mother Dragon landed was Ha Long, and where the Child Dragons came down was Bai Tu Long. The place where their tails violently wagged was called Long Vi, the present-day Tra Co Peninsula with its soft sandy beach stretching many kilometers.”
