Phong Nha - Ke Bang National Park and Hin Nam No National Park are among the most outstanding and intact karst landscapes and ecosystems in the world . The karst formations developed during the Paleozoic period about 400 million years ago and can be considered the oldest, largest karst areas in Asia. Phong Nha - Ke Bang is located in Quang Tri, Vietnam, and Hin Nam No is in Khammouane, Laos, both of which feature karst landscapes and rich underground cave systems.
Phong Nha-Ke Bang ( Quang Tri , Vietnam) is a limestone mountain range formed 400 million years ago, covering hundreds of thousands of hectares, connecting with Hin Nam No (Kham Muon, Laos).
With the erosion of water and rock over hundreds of millions of years, the Phong Nha-Ke Bang and Hin Nam No limestone mountains have created hundreds of caves and underground rivers with shimmering, mysterious beauty.
In 2003, Phong Nha-Ke Bang was recognized by UNESCO as a World Natural Heritage site based on geological and geomorphological criteria. Since then, Phong Nha-Ke Bang has become more widely known thanks to the exploration and research of many organizations, individuals, and scientists , including the British Royal Caving Association.
In 2015, Phong Nha-Ke Bang was recognized by UNESCO as a World Natural Heritage for the second time, with biodiversity criteria.
In 2009, an expedition team from the British Royal Caving Association collaborated with a local named Ho Khanh to discover Son Doong Cave - the world's largest cave, located in the core of Phong Nha-Ke Bang National Park.
In 2014, Son Doong Cave was put into tourism exploitation for adventurous tourists. Along with Son Doong, many caves with mysterious beauty in Phong Nha-Ke Bang have contributed to putting Phong Nha-Ke Bang on the world tourism map, turning Phong Nha into an attractive destination for domestic and foreign tourists.
Tourism products in Phong Nha-Ke Bang are considered diverse and rich, but the most unique is still adventure tourism.
After hundreds of millions of years of erosion by water and rock, nature has created unique masterpieces in Phong Nha-Ke Bang.
Phong Nha-Ke Bang has helped Quang Tri establish itself on the world tourism map.
Adventure tourism in Phong Nha-Ke Bang is attracting visitors from all over the world.
International cooperation to preserve and promote heritage is a top priority of Phong Nha-Ke Bang.

This is an opportunity for the two national parks to cooperate, promote and preserve the full value of the heritage.
