Halong Bay

Local legend says that long ago when the Vietnamese were fighting Chinese invaders, the gods sent a family of dragons to help defend the land. This family of dragons descended upon what is now Ha Long Bay (hence the name "Bay of Descending Dragons") and began spitting out jewels and jade. These jewels turned into the islands and islets dotting the bay, linking together to form barriers against the invaders. The people kept their land safe and formed what later became the country of Vietnam. A modern legend claims that a creature named the tarasque still lives in the bay.

History shows that Halong Bay has been the setting for local naval battles against Vietnam's coastal neighbours. On three occasions in the labyrinth of channels in Bach Dang river near the islands the Vietnamese army stopped the Chinese from landing. In 1288 General Tran Hung Dao stopped Mongol ships from sailing up the nearby Bach Dang River by placing steel-tipped wooden stakes at high tide, sinking the Mongol Dubhai Khan's fleet.

During the Vietnam War, many of the channels between the islands were heavily mined by the navy of the United States, some of which pose a threat to shipping to this day.

The surrounding land region of Halong City is rich with high grade coal deposits (anthracite), and is operated by the Vietnamese government.
