Legend says that dragons once descended from the heavens to protect Vietnam, scattering jade into the sea that formed thousands of limestone islands. These islands became what we now know as Ha Long Bay, meaning “Descending Dragon Bay.”

Located in northern Vietnam, Ha Long Bay is one of the country’s most breathtaking natural wonders. The UNESCO World Heritage Site is famous for its emerald waters and more than 1,600 limestone islands rising dramatically from the sea.

For many travelers, visiting Ha Long Bay is the highlight of a Vietnam trip. Cruising through the bay reveals hidden caves, floating fishing villages and secluded beaches surrounded by towering karst formations.

Most visitors reach Ha Long Bay from Hanoi, making it one of the most popular day trips or overnight cruise experiences from the capital. If you're planning a wider trip across the country, our Vietnam Travel Guide explains how Ha Long Bay fits into a complete itinerary across Vietnam.
