Hạ Long Bay, Vietnam
Ha Long Bay, in the Gulf of Tonkin, includes some 1,600 islands and islets, forming a spectacular seascape of limestone pillars. Because of their precipitous nature, most of the islands are uninhabited and unaffected by a human presence. The site’s outstanding scenic beauty is complemented by its great biological interest.
The outstanding value of the property is centered around the drowned limestone karst landforms, displaying spectacular pillars with a variety of coastal erosional features such as arches and caves which form a majestic natural scenery. The repeated regression and transgression of the sea on the limestone karst over geological time has produced a mature landscape of clusters of conical peaks and isolated towers which were modified by sea invasion, adding an extra elemant to the process of lateral undercutting of the limstone towers and islands.
Hạ Long Bay, in northeast Vietnam, is known for its emerald waters and thousands of towering limestone islands topped by rainforests. Junk boat tours and sea kayak expeditions take visitors past islands named for their shapes, including Stone Dog and Teapot islets. The region is popular for scuba diving, rock climbing and hiking, particularly in mountainous Cát Bà National Park.
