Ha Long Bay - Cat Ba Archipelago
Vietnam ·
Description
Ha Long's extension toward Cat Ba reveals the wild side of this legendary landscape. While Ha Long attracts crowds, Cat Ba offers deserted bays, unexplored caves, and the region's only national park. Golden-headed langurs, among the world's rarest primates, inhabit cliffs plunging into emerald waters where local fishermen maintain centuries-old traditions.
Why It's a World Heritage Site
Ha Long's extension to Cat Ba was recognized to protect additional karst ecosystems of exceptional beauty. UNESCO expanded the site to include Cat Ba's unique biodiversity, home to the critically endangered golden-headed langur.
