Baie d’Ha Long – archipel de Cat Ba
Viêt Nam
Located in northeastern Vietnam, this natural site comprises a complex maritime landscape characterized by limestone karst formations rising dramatically from the waters of the Gulf of Tonkin. The archipelago consists of numerous islands and islets with steep rocky peaks, caves, and rock shelters, interspersed with deeper waters and shallow lagoons. The site represents a significant example of subtropical karst topography in a marine setting, featuring exceptional geological formations and a diverse ecosystem that supports varied flora and fauna adapted to both terrestrial and aquatic environments. The area's limestone geology has created extensive cave systems and distinctive geological structures that reflect the region's complex tectonic and erosional history. The combination of dramatic natural scenery, geological importance, and ecological value justifies its recognition as a natural heritage site of international significance.
