Wilderness Landscape & Natural Heritage
Phia Oac-Phia Den National Park is located in the northeastern region of Vietnam within Cao Bang Province. It encompasses the rugged terrain of the Phia Oac and Phia Den mountain ranges, rising to elevations over 1,900 meters. The park protects a large expanse of subtropical forest that is home to diverse flora including coniferous and broadleaf species, as well as rare medicinal plants. This area is recognized as a key biodiversity hotspot, sheltering numerous endangered species such as the Tonkin snub-nosed monkey, crested gibbons, and various pheasants. The park's limestone karst formations and high mountain ridges create ideal habitats for both wildlife and adventurous visitors seeking remote trekking experiences. Historically, the area is part of the Sino-Vietnamese border region and contains local ethnic minority villages, offering unique cultural encounters. Outdoor enthusiasts can enjoy multi-day trekking routes through dense forests, mountain summits with panoramic views, and opportunities for wildlife watching. The relative remoteness and limited infrastructure mean the park sees fewer visitors, ensuring a tranquil and immersive nature experience for those who make the journey. Phia Oac-Phia Den is highly valued for conservation and eco-tourism, providing a natural refuge in Vietnam’s highlands and an appealing destination for wildlife researchers and eco-tourists alike.
