The karst formation of Phong Nha-Ke Bang National Park has evolved since 400 million years ago and so is the oldest major karst area in Asia. 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 to the west. The property comprises an area of 85,754 ha.



The karst formation process has led to the creation of not only underground rivers but also a variety of cave types including; dry caves, terraced caves, suspended caves, dendritic caves and intersecting caves. With a length of over 44.5 km the Phong Nha cave is the most famous of the system with tour boats able to penetrate inside to a distance of 1,500 m.



A large number of faunal and floral species occur within the property with over 568 vertebrate species recorded comprising 113 mammals, 81 reptiles and amphibians, 302 birds and 72 fish. This impressive level of biodiversity and species richness includes a number of endemic species as well as threatened species including tiger, Asiatic black bear, Asian elephant, giant muntjac, Asian wild dog, gaus and the recently discovered sao la.



Phong Nha is part of a larger dissected plateau, which also encompasses the Ke Bang and Hin Namno karsts. The limestone is not continuous and demonstrates complex interbedding with shales and sandstones. This, together with the capping of schists and apparent granites has led to a particularly distinctive topography.
