The Dong Van Karst Plateau is a high limestone upland of about 2,350 km² along Vietnam’s border with China, covering the old districts of Quan Ba, Yen Minh, Dong Van and Meo Vac. It became Vietnam’s first member of the Global Geoparks Network in 2010 and is now a UNESCO Global Geopark, recognised for rocks spanning more than 500 million years, rich fossil beds and some of the most extreme karst scenery in Southeast Asia.
It is not a fenced park. It is a farmed, lived-in region of over 300,000 people, and the Ha Giang Loop runs straight through it.

A UNESCO Global Geopark is an area with geology of international importance that is managed for protection, education and local development at the same time. Unlike a national park, it does not move people out or put up gates. There is no ticket for the Dong Van geopark itself; you pay only at individual sites such as the Lung Cu flag tower or the Vuong family palace.
| Year | What happened |
|---|---|
| 2010 | Admitted to the Global Geoparks Network in October, the first in Vietnam |
| 2014 | First revalidation |
| 2015 | UNESCO creates the formal UNESCO Global Geopark label; Dong Van carries it from then on |
| 2019 | Second revalidation |
| 2023 | Third recognition, marked with a ceremony in October |
| 2026 | A new provincial regulation for the geopark takes effect on 10 May, dividing it into core, buffer and transition zones |
Membership is reviewed every four years. The plateau has kept it each time, and since July 2025 the geopark sits in Tuyen Quang province after Ha Giang was merged into it.
The rocks, the fossils and why it looks the way it does
Around 60 per cent of the plateau is carbonate rock, mostly limestone, laid down in ancient seas. The oldest layers date to the Cambrian, more than 500 million years ago, and the sequence runs up through the Devonian and into the Permian, in places more than 3,000 m thick. Researchers have identified over a hundred geoheritage sites across the area.
Two layers matter to geologists worldwide. Both record mass extinctions: one near the end of the Devonian, about 360 million years ago, and the great Permian–Triassic extinction, about 250 million years ago. The fossil record includes trilobites, ancient fish, brachiopods, corals and plant remains.
The shapes you will see
Rain and slightly acidic groundwater dissolve limestone slowly, and uplift has lifted the whole block to between roughly 1,000 and 1,600 m. The result is a landscape of clustered peaks with closed hollows between them, bare grey rock fields, sinkholes, caves, and deep canyons where rivers have cut down through the plateau, the Nho Que most dramatically.
| Landform | What it looks like from the road | Where to see it on the loop |
|---|---|---|
| Peak clusters | Rows of cone-shaped hills with bowl-shaped valleys between | Quan Ba, Yen Minh, the Tham Ma slopes |
| Rock fields | Slopes of grey stone with maize planted in pockets of soil between the rocks | Around Sung La, Dong Van and Meo Vac |
| Canyon | A gorge hundreds of metres deep with a river at the bottom | Ma Pi Leng and Tu San |
| Caves | Openings in cliff faces, some with walkways | Lung Khuy cave near Quan Ba |
Where the loop shows the plateau best
The geology is everywhere once you climb out of Ha Giang city, but a few places make it easy to read.
Quan Ba Heaven Gate
The first high lookout, at about 1,500 m. Below it the Twin Mountains stand in a flat valley floor, a clean example of karst hills left standing as the land around them dissolved.
The rock fields between Yen Minh and Dong Van
Past the Tham Ma pass the ground turns grey. Families here farm maize and beans in hollows between boulders and build walls and house foundations from the stone they clear. Sung La valley and the Vuong family palace at Sa Phin both sit in this belt.
Ma Pi Leng and Tu San canyon
The clearest cross-section of the plateau. From the road at about 1,500 m you look straight down to the Nho Que, which has cut Tu San canyon through the limestone, with walls of roughly 700 to 900 m. The Ma Pi Leng Pass guide covers the lookouts and how long to stop at each.
Meo Vac and the border hills
On the far side of the pass, Meo Vac lies in a bowl of bare karst, and the hills around Lung Cu in the north carry the plateau up to the border itself.
The people on the plateau
The geopark counts 17 ethnic groups. H’Mong make up more than 60 per cent of the population and have lived here for several centuries; Lo Lo, Pu Peo, Co Lao, Bo Y, Dao, Tay and others live alongside them. Much of what visitors photograph is how people have adapted to stone: rammed-earth houses with yin-yang tile roofs, dry-stone walls around fields, and water tanks in villages where streams disappear into the rock.
Tourism has grown fast. Official figures put visitor numbers at about 2,000 in 2010 and 2.2 million in 2022, and the towns have filled with new hotels to match. The new 2026 regulation is partly an attempt to control what gets built in the core zones.
Seeing it by car
Every stop above is on the road our tours use. On the three-day loop from Ha Giang city you cross the plateau from Quan Ba to Dong Van on day one and spend day two between Lung Cu, the Vuong palace, Ma Pi Leng and the Nho Que. The four-day trip from Hanoi covers the same ground on days two and three. The route and timings are laid out in our Ha Giang Loop guide.
A car helps here in one specific way: the guide sits next to you and can explain the landscape as it changes, instead of at a stop over the noise of the road.
Four districts of stone plateau in three unhurried days
Three days from Ha Giang city or four door to door from Hanoi, private for your group and tailored on request.

Is the Dong Van Karst Plateau a UNESCO World Heritage Site?
No. It is a UNESCO Global Geopark, a different programme. It joined the Global Geoparks Network in 2010 and has been revalidated since, most recently with a third recognition in 2023.
How big is the Dong Van Karst Plateau?
About 2,350 km², mostly between 1,000 and 1,600 m above sea level, across the former districts of Quan Ba, Yen Minh, Dong Van and Meo Vac.
Do I need a ticket to enter the geopark?
No. There is no geopark entrance fee. Individual sites charge their own fees, and foreign visitors need a border-area permit for the four districts.
Where is the best place to see the karst plateau?
Ma Pi Leng Pass above the Nho Que River gives the clearest view of how deep the plateau has been cut. The rock fields between Yen Minh and Dong Van show how people farm it.
Is the Dong Van Karst Plateau the same as the Ha Giang Loop?
They overlap. The loop is a road circuit that starts in Ha Giang city, climbs onto the plateau at Quan Ba and runs across it to Meo Vac before dropping south.
