Phong Nha-Ke Bang National Park is located to the north of the majestic Truong Son Range in central Quang Binh Province. Phong Nha - Ke Bang is ancient karst area of the highest significance and value in both Vietnam and the world.
Phong Nha-Ke Bang National Park is one of the world's two largest limestone regions, and it has been recognised as a world natural heritage site by the United Nations Educational, Scientific and Cultural Organisation (UNESCO) at its 27th general assembly session being held in Paris from June 30-July 5, 2003. At the session, delegates from over 160 member countries of UNESCO World Heritage Convention agreed to include Phong Nha - Ke Bang Park and 30 others worldwide to the list of world heritage sites.
Phong Nha - Ke Bang Park is now the fifth UNESCO recognised site in Vietnam after Halong Bay, Hue Imperial City, Hoi An Ancient Town and My Son Cham Towers.
The over 200,000 ha of parkland includes beautiful limestone formations, grottoes and caves, and boasts lush forestland covering 95 percent of the park area.
The area is considered a paradise for researchers and explorers of grottoes and caves, and Vietnamese and British scientists have so far surveyed 20 with a total length of 70km. Of them, 17 are in the Phong Nha area and three in the Ke Bang Area.
The forest is also home to 32 sets, 98 families, 256 races and 381 species of four land backboned animals. Sixty-six animal species are listed in the Vietnam Red Book and 23 other species in the World Red Book.
Central Quang Binh Province has poured heavy investment into upgrading the Phong Nha - Ke Bang visitor site to turn it into the country's major tourist destination.
