Ha Long Bay, in northeastern Vietnam, is a breathtaking seascape where thousands of forested limestone islands rise dramatically from emerald waters. A UNESCO World Heritage Site since 1994, its name—“where the dragon descends into the sea”—recalls a legend of a mighty dragon carving valleys and crevasses as it charged toward the coast, leaving only the towering pinnacles visible once the waters rose. Today, the bay can be explored in style via opulent luxury superyachts, traditional Chinese-style junk boats, or even from above aboard scenic seaplane flights, offering unparalleled perspectives of the bay’s islands, hidden caves, and shimmering waters.
