A New UNESCO Milestone for Phong Nha – Ke Bang
Phong Nha – Ke Bang National Park has officially been recognized by UNESCO as a World Biosphere Reserve, marking a significant milestone in the conservation history of Vietnam and further strengthening the global reputation of this extraordinary natural heritage destination.

The recognition was approved on June 5, 2026, during the 38th Session of UNESCO’s International Coordinating Council of the Man and the Biosphere (MAB) Programme held in Hernandarias, Paraguay. This achievement represents the third major UNESCO recognition awarded to Phong Nha – Ke Bang, following its inscription as a UNESCO World Natural Heritage Site in 2003 and its expanded recognition for biodiversity values in 2015.
The new designation highlights the area's outstanding ecological value and confirms its importance as one of the world's most significant regions for biodiversity conservation, scientific research, and sustainable development.
What Is a UNESCO World Biosphere Reserve?
A UNESCO World Biosphere Reserve is an internationally recognized area where the conservation of biodiversity is balanced with sustainable economic and social development. Established under UNESCO’s Man and the Biosphere Programme, these reserves serve as "living laboratories" where communities, scientists, governments, and conservationists work together to protect natural ecosystems while supporting local livelihoods.

Unlike strictly protected nature reserves, biosphere reserves encourage a harmonious relationship between people and nature. They promote environmental protection, scientific research, education, sustainable tourism, and community-based development.
The Outstanding Value of Phong Nha – Ke Bang
Located in central Vietnam, Phong Nha – Ke Bang is one of Southeast Asia’s most remarkable natural landscapes. The park is famous for its vast limestone mountain system, ancient tropical forests, underground rivers, and hundreds of spectacular caves.
The area is home to some of the world's most extraordinary cave systems, including Son Doong Cave, the largest natural cave on Earth, along with Paradise Cave, Phong Nha Cave, Hang En Cave, and numerous other underground wonders. These geological formations have evolved over hundreds of millions of years, creating a unique karst ecosystem of global scientific significance.
Beyond its geological treasures, Phong Nha – Ke Bang supports exceptional biodiversity. The national park contains extensive tropical limestone forests and provides habitat for many rare and endangered plant and animal species. Scientists continue to discover new species and previously unknown cave systems within the park, demonstrating its ongoing ecological importance.
Scale and Structure of the Biosphere Reserve
According to the dossier approved by UNESCO, the Phong Nha – Ke Bang World Biosphere Reserve covers a total area of 515,830 hectares.
The reserve consists of:
- Core Zone: 123,326 hectares
- Buffer Zone: 220,055 hectares
- Transition Zone: 172,449 hectares
The biosphere reserve is home to more than 159,300 residents who live within and around the protected area. This zoning model allows conservation activities to coexist with sustainable economic development, creating opportunities for local communities while preserving the area's exceptional natural resources.
