From March 6-26, British ITV Studio will make a TV documentary about Son Doong cave and biodiversity in Phong Nha-Ke Bang National Park.
US filmmakers from National Geographic will also visit the newly-discovered grotto to shoot a film. This survey will feature the famous British explorer, Howard Limbert and will be broadcast in 120 countries in various languages.
In January 2010, Canada’s Yap Films Ltd. produced a TV documentary about Phong Nha-Ke Bang. Filmmakers from TV channels in Germany and Japan have also visited.
The presence of foreign filmmakers and reporters once again demonstrates the value and interest of the international community in this world natural heritage site, especially Son Doong cave and the surrounding karst grottos.
In mid-2009, the British Royal Cave Society announced the discovery of the world’s largest cave in the Phong Nha-Ke Bang national park by Ho Khanh, who had named it Son Doong. The cave is 2 kilometers in length, 150 meters at the highest point, and 90 meters wide.
Before this site was discovered, Deer Cave in Malaysia was recognized as the world’s biggest cave at 100 meters high, 90 meters wide and 2 kilometers long.
Phong Nha-Ke Bang National Park is located in Bo Trach and Minh Hoa districts in the centre of Quang Binh province. 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.
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
