Introduction to Hin Nam No National Park’s UNESCO Recognition
On July 13, 2025, Hin Nam No National Park in Khammouane Province, Laos, was officially inscribed as Laos’ 4th UNESCO World Heritage Site during the 47th Session of the World Heritage Committee in Paris, France. This monumental achievement marks the park as a Transboundary World Heritage Site, seamlessly connecting with Vietnam’s Phong Nha-Ke Bang National Park to form the world’s largest contiguous limestone karst landscape. Spanning 94,121 hectares in southeastern Laos, Hin Nam No National Park showcases unparalleled geological wonders, extraordinary biodiversity, and deep cultural significance. From the majestic Xe Bang Fai Cave to rare species like the Red-Shanked Douc Langur, this park is a must-visit for eco-tourists and nature enthusiasts. In this guide, we explore why Hin Nam No National Park’s UNESCO status makes it a top destination, its unique features, travel tips, and how to plan your Laos tour packages to this destination.
Why Hin Nam No National Park Earned UNESCO World Heritage Status
Hin Nam No National Park’s inscription as a UNESCO World Heritage Site is a testament to its Outstanding Universal Value (OUV), recognized under three UNESCO criteria: geology and geomorphology (viii), ecosystems (ix), and biodiversity (x). Here’s why this park stands out:
Geological Marvels of Hin Nam No
The park’s name, “Hin Nam No,” meaning “mountain crest, spiky as bamboo shoots” in Lao, reflects its dramatic limestone karst formations, shaped over 300 million years. Covering 94,121 hectares, the park features towering cliffs soaring over 300 meters, remote valleys, and 173 documented caverns, including the Xe Bang Fai Cave, one of the world’s largest active underground river systems with passages up to 120 meters tall and 200 meters wide. This geological complexity, formed in the Paleozoic era, creates a pristine landscape that rivals global karst systems.
Unmatched Biodiversity in the Indo-Burma Hotspot
Located within the Indo-Burma biodiversity hotspot, Hin Nam No National Park is a sanctuary for over 1,500 plant species and 536 vertebrate species, many of which are endemic or globally threatened. Notable species include:
Red-Shanked Douc Langur: A vibrant primate unique to the region.
Sunda Pangolin: A critically endangered mammal.
Lao Rock Rat: A “living fossil” discovered in 2005, exclusive to Khammouane Province.
Giant Huntsman Spider: The world’s largest spider, thriving in the park’s caves.
Southern White-Cheeked Gibbon: Among the largest remaining populations in the world.
The park’s diverse habitats—evergreen forests, mixed deciduous forests, and karst-specific ecosystems—support this rich biodiversity, making it a critical conservation area.
Cultural and Historical Significance
Beyond its natural wonders, Hin Nam No National Park is a cultural treasure. Several ethnic minority communities, such as the Brou and Katang, reside within its boundaries, preserving distinct traditions, languages, and lifestyles. These communities maintain a deep connection to the land, practicing sustainable agriculture and spiritual rituals tied to the karst landscape. The park’s cultural heritage complements its natural value, making it a mixed heritage site that celebrates both nature and human history.
Transboundary Collaboration with Phong Nha-Ke Bang
Hin Nam No’s UNESCO inscription as a transboundary site with Vietnam’s Phong Nha-Ke Bang National Park creates a conservation corridor spanning over 217,447 hectares (123,326 hectares in Phong Nha-Ke Bang and 94,121 in Hin Nam No). This partnership, formalized through a 2018 Memorandum of Understanding (MoU) between Laos and Vietnam, enhances cross-border efforts in biodiversity protection, sustainable tourism, and community development. The combined site, officially named Phong Nha-Ke Bang and Hin Nam No National Parks, is the first transboundary natural World Heritage Site in Southeast Asia.

Travel Tip: Early morning or dusk tours increase chances of spotting wildlife. Bring binoculars and a camera with a zoom lens.

Best Time to Visit Hin Nam No National Park
The dry season (November-March) is the best time to visit Hin Nam No National Park, offering cool, dry weather (15-25°C/59-77°F) ideal for hiking, cave exploration, and wildlife spotting.
