Welcome to Hin Nam No National Park, a natural marvel that spans an area of 94,121 hectares in southeastern Laos. This biodiverse and stunningly beautiful protected zone shelters some of the planet’s most spectacular, mysterious, and highly threatened biodiversity and harbors an array of ecosystems, including pristine forests, majestic waterfalls, and intricate cave systems such as the Xe Bang Fai Cave, the largest documented active cave river in the world. Hin Nam No sits in the middle of the rugged Central Annamite Mountains that form the border between Vietnam and Laos. It shares its eastern border with the Natural World Heritage site “Phong Nha-Ke Bang" of Vietnam, and together, they form the world’s largest contiguous limestone karst landscapes.

The name “Hin Nam No" translates as “mountain crest, spiky as bamboo shoots" and is testament to this rugged limestone forest landscape’s signature sharp spires, formed by 300 million years of geology. Hin Nam No’s to-date recorded 173 caves, and its spectacular steep cliffs that reach up to 300 meters form secluded, isolated habitats deep inside caves or in secluded valleys where animal species could evolve largely isolated from other populations.

Hence, one of the defining features of Hin Nam No National Park is its high level of biodiversity. The park is home to an incredible range of species, including many that are found nowhere else on earth. These include rare and exotic birds, mammals, reptiles, and plants, making the area a true natural treasure.

But the park is not only a place of natural wonders. It is also a site of cultural and historical significance. The park is home to several ethnic minority groups, each with their own unique traditions, customs, and ways of life. Come witness the rich cultural heritage of these communities and the deep connection between people and nature!
