Tà Đùng covers 20,938 hectares of the highest mountain range in Đắk Nông province, sitting at a biological crossroads where the South Central Highlands meet the Southeast region. The park straddles National Highway 28, running about 45 kilometers southeast from the provincial capital of Gia Nghĩa, and its southern edge follows the upper Đồng Nai River, squeezed between the Dong Nai 3 and Dong Nai 4 hydropower reservoirs. The border between Đắk Nông and Lâm Đồng provinces traces the river's original course before the reservoir swallowed the valley. Standing on the ridgeline today, you look out over a landscape that is half ancient forest and half new blue water — the dam projects that now define the southern boundary created a reservoir that has, paradoxically, become its own kind of spectacle.

The Ma people — also called the Mạ — are an ethnic minority group of the Central Highlands whose relationship with this mountain predates written records. Their tradition of naming every stream, hill, and hollow in the Tà Đùng massif is not merely poetic; it is an ecological memory system, a way of encoding which paths flood in the rains, where the medicinal plants grow, which ridges the animals use. Elder K'Cha's continued teaching of these stories is itself a form of conservation work. Today the Ma cooperate directly with forest rangers to combat illegal logging — a partnership that blends indigenous landscape knowledge with official enforcement. Where government patrols might miss a track, the Ma already know it.

Tà Đùng is not simply a wildlife sanctuary; it functions as a water tower for millions of people downstream. The Đồng Nai River basin, which the park's riparian zones help regulate, supplies drinking water, irrigation, and hydroelectric power across Vietnam's densely populated Southeast region. The park also protects rare and endangered species within its strict protection zone, while its ecological restoration zones work to repair damaged habitat. Scientific research stations operate within the boundaries, studying biodiversity and water dynamics. The three functional zones — strict protection, ecological restoration, and service-administration — reflect a careful attempt to balance conservation with the needs of surrounding communities.

The challenge facing Tà Đùng is one familiar to protected areas across Southeast Asia: the forest contains large, valuable hardwood trees, and that value attracts illegal loggers willing to push deep into the park. The remoteness that makes the highland forest so ecologically significant also makes enforcement difficult. The park authority has leaned into the Ma community's role as forest guardians, recognizing that a patrol of rangers can cover only so much ground. Villagers who know every path and listen for the sound of chainsaws provide a network of eyes that no official force could replicate. The park is young — it has existed formally for only about eight years — and the contest between protection and exploitation is still very much ongoing.

Upgraded from a nature reserve in 2018, Tà Đùng is one of Vietnam's newer national parks, but the land it protects has been tended and storied for far longer. The transition from reserve to national park came with stricter protections and greater resources, and the buffer zone around the core — with its 45-kilometer reach into Đăk Glong District — gives conservationists space to manage the edges of the wilderness. For visitors making the journey from Gia Nghĩa, the park offers a landscape of cloud forest and cascading streams that feels genuinely remote. For the Ma people, it is simply home — finally, officially, protected.
