Phong Nha-Ke Bang National Park Vietnam
The karst formation of Phong Nha-Ke Bang National Park has evolved since the Palaeozoic (some 400 million years ago) and so is the oldest major karst area in Asia. Subject to massive tectonic changes, the park's karst landscape is extremely complex with many geomorphic features of considerable significance. The vast area, extending to the border of the Lao People's Democratic Republic, contains spectacular formations including 65 km of caves and underground rivers. Phong Nha - Ke Bang National Park is located in the middle of the Annamite Mountain Range in Quang Binh province, Vietnam and shares its boundary with the Hin Namno Nature Reserve in the Lao PDR to the west. The property comprises an area of 85,754 ha and contains terrestrial and aquatic habitats, primary and secondary forest, sites of natural regeneration, tropical dense forests and savanna and is rich in large, often spectacular and scientifically significant caves.
