Phong Nha - Ke Bang National Park


Phong Nha-Ke Bang National Park is located in Bo Trach and Minh Hoa districts in the centre of Quang Binh province. The park is bordered by Laos to the west. The road distances are about 500 km south of the capital Hanoi and 260 km north of the port city of Da Nang. It protects one of the world’s two largest karst regions with several hundred caves and grottoes.

Phong Nha-Ke Bang National Park was first nominated as a UNESCO World Heritage Site in 1998. It was recognised as a world natural heritage site at UNESCO’s 27th general assembly session in Paris from June 30-July 5, 2003.

Phong Nha-Ke Bang National Park is one of the world’s two largest limestone regions. In comparison with 41 other world heritage sites which have karsts, Phong Nha has dissimilar geomorphic, geologic and biotic conditions. The karsts of Phong Nha can be traced back to the Palaeozoic era, 400 million years ago. This makes Phong Nha the oldest major karst in Asia. If the Hin Namno, bordering Phong Nha on the west (in Laotian territory), was to be combined with the national park in a continuous reserve, the combined reserve would be the largest surviving karst forest in Southeast Asia (317,754 ha).

The area has numerous grottoes and caves. Vietnamese and British scientists have so far surveyed a total of 20 caves with a total length of 70km. Of these surveyed caves, 17 are in the Phong Nha area and three in the Ke Bang area.

The Phong Nha cave from which the name of the whole system and the park is derived is famous for its rock formations which have been given names such as the "Lion", the "Fairy Caves", the "Royal Court", and the "Buddha".

Besides the grotto and cave systems, Phong Nha has the longest underground river, the largest caverns and passageways. Phong Nha-Ke Bang also contains two dozen mountain peaks of over 1,000 metres in height. Noteworthy peaks are the Peak Co Rilata with a height of 1,128 m and Peak Co Preu with a height of 1,213 m.
