Crossing Borders, Preserving Wonders: The Rise of a Transboundary Treasure

A Shared World Heritage in the Heart of the Mekong

Straddling the lush, forested border between Viet Nam and Lao PDR, the Phong Nha - Ke Bang and Hin Nam No National Parks have achieved a milestone of regional and global significance. Recently recognised as the first transboundary World Heritage site shared by the two countries, this remarkable karst landscape represents not only natural splendour but also a new era of cooperation between Mekong neighbours.

Carved by time and shaped by tectonic forces, this sprawling expanse of caves, cliffs, and tropical ecosystems is more than just a destination—it’s a symbol of partnership and preservation.

Caves That Tell Ancient Stories

Phong Nha - Ke Bang, already celebrated as one of Viet Nam’s most iconic national parks, is famed for its vast underground networks, including the legendary Son Doong Cave—currently regarded as the largest cave in the world. With colossal chambers, subterranean rivers, and surreal stalactite formations, it draws explorers and nature lovers from around the globe.

Just across the border in Lao PDR, Hin Nam No National Park offers its own geological marvels, with rugged limestone formations and rare species hidden in dense forest canopies. For years, this lesser-known gem has quietly contributed to the region’s biodiversity and ecological health. Together, these parks form a continuous karst ecosystem that is as vital as it is visually striking.

A Model of Cross-Border Conservation

The UNESCO inscription of this transboundary heritage site is more than a conservation success—it’s a testament to diplomatic goodwill, long-term vision, and community-based environmental stewardship. Viet Nam and Lao PDR have worked hand-in-hand to align policies, share knowledge, and empower local communities to play a central role in protecting their shared natural heritage.

This collaborative approach strengthens the resilience of the parks in the face of challenges such as climate change, tourism pressures, and habitat loss, ensuring that future generations will inherit a thriving ecosystem.

Ecotourism with Purpose and Depth

For travellers seeking more than scenic views, the twin parks offer a meaningful adventure into one of Southeast Asia’s last great wildernesses. Whether kayaking through emerald rivers, trekking through remote forest trails, or visiting ethnic minority villages along the way, visitors can experience both the grandeur of nature and the richness of local culture.

With responsible tourism initiatives growing in both countries, the transboundary site is poised to become a flagship example of ecotourism done right—balancing access with protection and delivering real benefits to border communities.
