Phong Nha-Ke Bang National Park has been rated by the ASEAN travel site GoAsean as one of seven national parks that travellers should visit in in Southeast Asia.
                             

 
According to the  travel site GoAsean, located in Quang Binh Province, Phong Nha-Ke Bang  National Park was recognized as a UNESCO World Heritage Site in 2003.  Phong Nha-Ke Bang has the most magnificent system of underground rivers  in Southeast Asia. The national park is also home to some of the world’s  most unique forms of flora and fauna, including hundreds of different  species of birds.
 
Goasean said of  the park, “It spans well over 800 square kilometers in area, and this  means that you would probably need more than a day to experience its  cavernous wonders.”
 
Famous for  having over 300 caves and grottos, the park spans over 800 square  kilometers in area. In April 2009, Son Doong Cave, one of the world’s  largest caves, was discovered in Phong Nha-Ke Bang by a team of British  cave explorers led by a local farmer.
 
Other national  parks also on the list include the Bromo Tengger Semeru National Park in  Indonesia, Gunung Mulu National Park in Malaysia, Doi Inthanon National  Park in Thailand, Taman Negara in Malaysia; Khao Sok in Thailand and  Komodo in Indonesia.
