Bach Ma National Park protects a major tropical and subtropical evergreen forest landscape south of central Hue. The park was established in 1991 and later expanded; the ASEAN Centre for Biodiversity currently records an ASEAN Heritage Park area of 406.945 km² and recognition in 2022. Its steep elevation gradient, exceptionally wet climate and position near a major biogeographic transition support rich flora and fauna, while its forests protect headwaters feeding the Ta Trach, Truoi and Cu De river systems.
Overview
Understand the park as a protected ecological system, not simply a recreation area.
Bach Ma National Park occupies a dramatic mountain landscape between Hue and the central coast, on the northern Truong Son/Annamite system. It was established as a national park in 1991 with an initial area of 22,031 hectares and subsequently expanded. Modern sources use different extents: scientific literature often describes a 37,487-hectare core, while the ASEAN Centre for Biodiversity lists 406.945 km² for the ASEAN Heritage Park. These figures must remain tied to their source and boundary context rather than being merged. Bach Ma is one of Vietnam's wettest mountain landscapes, with national conservation information reporting typical annual rainfall around 3,400–4,000 mm and exceptional totals that can be much higher. Forest habitats range from tropical evergreen forest below roughly 1,000 metres to subtropical evergreen forest at higher elevations. ACB currently reports 2,421 flora species and 1,728 fauna species in its compiled park profile. The park was recognized as an ASEAN Heritage Park in 2022, with the certificate formally presented during the 8th ASEAN Heritage Parks Conference in December 2025. Its conservation identity combines biodiversity, watershed protection, forest restoration, controlled ecotourism, historic Bach Ma hill-station remains and the Hai Vong Dai–Ngu Ho–Do Quyen visitor landscape.
Key things to understand
Treat Bach Ma as a mountain-forest and watershed system rather than only a summit viewpoint.
Keep the 22,031-ha founding area, 37,487-ha later core figure and 40,694.5-ha ASEAN Heritage Park extent separately scoped.
Recognize ASEAN Heritage Park status as a biodiversity designation, not UNESCO World Heritage.
Understand the park's exceptional rainfall as a driver of forest, streams, waterfalls and visitor risk.
Read the elevation gradient as a transition from tropical to subtropical evergreen forest.
Use Hai Vong Dai as a landscape-orientation point rather than the definition of the whole park.
Treat Ngu Ho and Do Quyen Waterfall as hydrological and ecological landscapes as well as visitor attractions.
Respect red-shanked douc, pangolins and other threatened wildlife without promising sightings.
Keep historic French-era hill-station remains subordinate to the park's nature-conservation identity.
Check rain, fog, road and trail conditions before ascending.
Stay on authorized routes and avoid disturbing wildlife or collecting forest material.
Treat current ecotourism planning as conservation-led rather than a mandate for unlimited visitor growth.
Park perspective
How to understand this protected landscape
Why it matters
Bach Ma protects an exceptionally wet mountain-forest transition where biodiversity conservation and watershed security directly support the landscapes and communities below.
What makes it distinctive
A steep elevation gradient, extreme rainfall, rich forest biota and a historic summit landscape are compressed into a relatively accessible mountain system near Hue.
What visitors often miss
The dramatic viewpoint and waterfalls are consequences of the larger forest-and-water system; watershed conservation is as important as scenery.
A cool, rain-soaked forest mountain above Hue where tropical and subtropical habitats, waterfalls, rare wildlife and historic hill-station remains meet.

Common misconceptions
01
Bach Ma is a national park; ASEAN Heritage Park is an additional regional recognition.

04
Rain and fog are normal ecological features, not merely bad sightseeing weather.
05
The summit viewpoint is only one small part of the park.
06
Rare wildlife sightings are not guaranteed.
07
Historic Thua Thien Hue/Quang Nam boundary descriptions should not automatically be treated as current post-reorganization administrative geography.

Questions
Frequently asked questions
What is Bach Ma National Park?
It is a mountain national park centered south of Hue that protects tropical and subtropical evergreen forest, watersheds and exceptional biodiversity.
When was Bach Ma National Park established?
The modern national park was established in 1991 with an initial area of 22,031 hectares.
How large is Bach Ma?
Different official and scientific contexts use different extents: 22,031 ha at establishment, 37,487 ha in later core-area research, and 40,694.5 ha in the ASEAN Heritage Park profile.
Why are there different area figures?
They represent different establishment, management/core and ASEAN-designation boundaries; they should not be merged.
Is Bach Ma an ASEAN Heritage Park?
Yes. ACB records recognition in 2022, and Vietnam formally presented the certificate at the ASEAN Heritage Parks Conference in December 2025.
Is Bach Ma a UNESCO World Heritage Site?
No. ASEAN Heritage Park is a separate regional protected-area recognition.
Why is Bach Ma so wet?
Its mountain position near the central coast intercepts moisture; national conservation reporting gives typical annual rainfall around 3,400–4,000 mm, with exceptional years or locations much wetter.
How high is Bach Ma?
The broader Key Biodiversity Area ranges to about 1,448 metres elevation.
What forest types occur there?
National conservation information describes tropical evergreen forest below roughly 1,000 m and subtropical evergreen forest above it.
How biodiverse is it?
ACB currently reports 2,421 flora species and 1,728 fauna species, while detailed taxonomic surveys provide additional counts that vary by method and date.
What wildlife is Bach Ma known for?
Threatened forest wildlife includes red-shanked douc langurs and rare birds, while camera-trap monitoring has also recorded other protected mammals.
Can I expect to see rare mammals?
No. Wildlife sightings are never guaranteed and sensitive locations should not be disclosed.
What is Hai Vong Dai?
A historic summit viewpoint providing broad landscape orientation when cloud and fog permit.
What is Ngu Ho?
A forest trail through a series of five pools and cascades.
What is Do Quyen Waterfall?
A major mountain waterfall illustrating Bach Ma's very wet climate and steep hydrology.
Why is Bach Ma important for water?
Its forests protect headwaters associated with the Ta Trach, Truoi and Cu De river systems and other streams.
Does Bach Ma have colonial-era history?
Yes. It developed as a hill station from the 1930s, and historic ruins remain within the modern conservation landscape.
Is Bach Ma good for birdwatching?
Yes. It is a confirmed Key Biodiversity Area and multiple studies document high bird diversity.
Is the summit always clear?
No. Fog, cloud and rain are frequent and should be considered part of the mountain environment.
Can I swim in streams or pools?
Only where currently permitted and safe; heavy rain can quickly make water hazardous.
Can I drive to the summit?
Vehicle and shuttle rules can change. Check current park arrangements rather than relying on older travel information.
Can I fly a drone?
Do not assume permission; protected-area and aviation rules apply.
What should I verify before visiting?
Current weather, road status, trail openings, transport rules, ticketing and any waterfall or safety restrictions.
