Halong Bay is one of seven UNESCO World Heritage sites with nearly 2,000 limestone islands. Located in the Gulf of Tonkin, Halong Bay has been shaped by over a million-year geological evolution. Today, the bay has a diverse natural ecosystem, including hidden caves, grottoes, beaches, etc.
Beside natural wonders, the name "Ha Long" is also rich in meaning. In Sino-Vietnamese, Ha Long means "Descending Dragon," derived from the ancient legend about scared dragons. When traveling Ha Long, visitors can immerse themselves in the local lifestyle, by exploring floating fishing villages or learning about historical phases. So Halong Bay is really the must-visit destination for anyone traveling to Vietnam for the first time.
