Bidoup–Nui Ba National Park protects one of Vietnam's richest high-mountain forest landscapes around the Da Lat Plateau. Its official website currently states a total area of 69,662 hectares, while ASEAN Heritage Park documentation uses 550.53 km² and the 2026–2030 Lam Dong biodiversity-planning annex lists 56,436 hectares. These figures represent different administrative, recognition and planning scopes and are retained separately. The park is an ASEAN Heritage Park since 2018 and a core zone of the UNESCO Langbiang World Biosphere Reserve, recognized in 2015.
Overview
Understand the park as a protected ecological system, not simply a recreation area.
Bidoup–Nui Ba is a defining conservation landscape of the Southern Annamites and Da Lat Plateau. Its steep elevation gradients support subtropical moist evergreen rainforest, montane forest, mixed broadleaf–conifer forest, dry conifer forest, bamboo and major headwater systems. The park's current official website states 69,662 hectares and more than 1,933 vascular plant species, including more than 250 wild orchid species. ASEAN Centre for Biodiversity documentation uses a 550.53 km² ASEAN Heritage Park extent and reports 1,952 plant species, 131 mammals, 304 birds, 91 reptiles, 78 amphibians, 44 freshwater fish and 125 butterflies. Lam Dong's 2026–2030 biodiversity-planning annex separately lists 56,436 hectares for the national park. These numbers should not be silently reconciled because they reflect different datasets and spatial scopes. Bidoup–Nui Ba is particularly important for narrow-endemic conifers such as Pinus krempfii and Pinus dalatensis and for the Da Lat Plateau's endemic bird assemblage. The park became an ASEAN Heritage Park in 2018 and lies at the core of the UNESCO Langbiang Biosphere Reserve. Current 2026 management continues biodiversity inventory, camera-trap/acoustic monitoring, forest-fire coordination and international research cooperation. Visitor use should therefore remain conservation-led and route-specific.
Key things to understand
Treat Bidoup–Nui Ba as a national park and high-mountain forest system, not merely an extension of Da Lat sightseeing.
Keep the 69,662-ha official website figure, 550.53-km² ASEAN Heritage Park extent and 56,436-ha provincial planning figure source-scoped.
Recognize its 2018 ASEAN Heritage Park status without confusing it with UNESCO World Heritage.
Keep the park distinct from the wider UNESCO Langbiang World Biosphere Reserve, of which it is a core zone.
Highlight Pinus krempfii and Pinus dalatensis as exceptional narrow-endemic conifer conservation values.
Treat the Da Lat Plateau endemic-bird assemblage as a major global biodiversity feature.
Use orchid richness as a conservation story, never as an invitation to collect.
Respect high-elevation weather, fog, rain and forest-fire restrictions.
Use authorized routes and current park guidance.
Do not publish precise locations of rare plants, nests or threatened wildlife.
Treat biodiversity monitoring and research as active management, not static background information.
Keep the profile Nature Map-only; biosphere and ASEAN designations do not qualify it for the World Heritage Map.

05
Rare orchids and conifers are conservation assets, not souvenirs.
06
Endemic bird records do not guarantee sightings.
07
Research and monitoring sites are not automatically visitor-accessible.
