Its position at the center of a large karst region that stretches all the way to Hin Namno in Laos makes Phong Nha Ke Bang part of a transnational karst landscape.

The terrain is marked by rugged high mountains in the west, gradually descending toward the east where the Son River winds through the village of Son Trach before flowing out to the sea.
2. An overview of Phong Nha - Ke Bang National Park Vietnam
Phong Nha Ke Bang National Park covers a total area of 123,326 hectares and is located in the center of the limestone mountain region in the western part of Quang Binh Province. The park is divided into three functional zones: a strict protection zone of 100,296 hectares, an ecological restoration zone of 19,619 hectares and a service-administration zone of 3,411 hectares. This scientific zoning ensures effective conservation while also providing opportunities for research, education and sustainable tourism development.
Recognized by UNESCO as a World Natural Heritage Site, Phong Nha Ke Bang is renowned for its ancient limestone mountains, diverse terrain and pristine natural landscapes. Situated under dense tropical forest canopies, the area provides an ideal ecological environment for the growth of numerous plant and animal species including many rare and endemic species of the Truong Son range.
One of the park’s most remarkable values is its cave system which dates back millions of years and is considered the oldest in Southeast Asia. The entire area is often called the “Kingdom of Caves” with hundreds of large and small caves.
The two main systems are the Phong Nha cave system, famous for its underground rivers, grand cave entrances and intricate stalactites and stalagmites, and the Hang Vom system, notable for its wide chambers, impressive depth and characteristic karst formations. Many caves here are unique in scale, contributing to the park’s global reputation.
In 2003, UNESCO recognized Phong Nha Ke Bang as a World Natural Heritage Site based on its geological and geomorphological values, acknowledging the area as a “living karst museum” with a geological history spanning hundreds of millions of years. On July 3, 2015, the park was honored by UNESCO for the second time for its biodiversity and ecological significance, highlighting the importance of its primary forests and endemic habitats in the Truong Son range.

3. Geomorphology and Geology of Phong Nha Ke Bang
Phong Nha Ke Bang National Park is considered a “living geological museum” of international significance, notable for its complex geological structure and the diversity of rock types. The area includes sandstone, quartz, shale, silica-rich limestone, macne rock, granodiorite and many other rock types.
The geological history of Phong Nha Ke Bang spans approximately 400 million years, going through multiple important tectonic stages involving shifts, faults, folds and subsidence. These geological events not only created towering mountain ranges but also formed sedimentary basins and deep valleys, contributing to the diversity of terrain, landforms and the unique karst landscapes.
The limestone region here is characterized by long developmental stages from the Palaeozoic era about 400 million years ago to the late Carboniferous and Permian periods (340 to 240 million years ago). One of the most remarkable features of Phong Nha Ke Bang is the formation of underground rivers flowing through massive caves within the limestone mountains, creating a rich cave system of high scientific value.
In addition, the non-limestone landforms in the area generally consist of low mountains covered with dense vegetation. Long-term erosion has formed terraces along the valleys of the Son and Chay rivers, as well as at the base of the central limestone hills. The transitional terrain between the limestone mountains and the lowlands exhibits a variety of landforms, with alternating hills and small valleys, creating a globally rare diversity of landscape and geological structures.
