Hin Nam No National Park - A First UNESCO World Heritage Site at the Vietnam-Laos Border

Hin Nam No National Park - cross-border heritage between Vietnam and Laos

On July 13, 2025, a historic milestone was etched into the annals of global conservation as UNESCO officially inscribed the transboundary World Natural Heritage site, “Phong Nha - Ke Bang National Park and Hin Nam No National Park.” This recognition marks the first cross-border heritage between Vietnam and Laos, celebrating the extraordinary natural and cultural treasures of the region. Nestled in Khammouane Province, Hin Nam No National Park has earned its place as Laos’s UNESCO World Heritage Site, joining Vietnam’s Phong Nha - Ke Bang to form one of the world’s most remarkable karst landscapes. For adventurers and nature enthusiasts, this pristine wilderness offers unparalleled Vietnam Laos adventure tours, blending breathtaking scenery with profound cultural experiences. Let’s delve into the heart of this natural wonder and explore why National parks of Vietnam, Laos are capturing global attention.

A Geological and Biological Masterpiece

Spanning 94,121 hectares in southeastern Laos, Hin Nam No National Park forms one of the world’s largest contiguous limestone karst landscapes alongside Vietnam’s Phong Nha - Ke Bang National Park. The park is a geological treasure, featuring towering limestone cliffs, dense jungles, and an intricate network of 173 documented caverns, including the awe-inspiring Xe Bang Fai Cave, the world’s largest functioning underground river system. This remarkable karst system, formed over 400 million years, is a testament to the region’s ancient geological history, meeting UNESCO’s criteria for geology, geomorphology, ecosystems, and biodiversity.

Biologically, Hin Nam No is a sanctuary within the Indo-Burma biodiversity hotspot, hosting over 1,500 plant species and 536 vertebrate species. Rare and endemic species, such as the Red-Shanked Douc Langur, Sunda Pangolin, Lao Rock Rat, and the world’s largest spider, the Giant Huntsman Spider, thrive in this pristine environment. The park’s untouched beauty and ecological significance make it a haven for nature enthusiasts and scientists alike.

Cultural and Historical Significance

The significance of Hin Nam No National Park extends beyond its natural wonders to encompass a rich cultural heritage. Several ethnic minority communities, including the Lao, Bru, and Chut, call the park’s fringes home, preserving traditions, languages, and ways of life that have thrived for centuries. Caves like Tham Pha Daeng, adorned with ancient paintings, hint at the spiritual and historical connections these communities share with the land. This cultural mosaic enhances the park’s status as a cross-border heritage between Vietnam and Laos, symbolizing the deep ties between the two nations.

Since 2018, Vietnam and Laos have collaborated closely on conservation efforts, with Vietnam providing expertise in legislation, management, and training to support Laos’s heritage preservation. This partnership, formalized through the UNESCO nomination process, sets a global precedent for transboundary cooperation. For visitors, engaging with local communities—whether through homestays, cultural exchanges, or guided tours—offers a deeper understanding of the region’s living heritage, making Vietnam Laos adventure tours a journey through both nature and culture.
