Happiness Road is the name for National Highway 4C from Ha Giang city to Meo Vac, about 185 km built between September 1959 and March 1965 by youth volunteers and local labourers from the plateau’s ethnic groups. Its hardest stretch, the cliff over Ma Pi Leng, was cut with hammers, steel chisels and explosives by workers hanging on ropes.
Ho Chi Minh gave the road its name in 1961. Today you drive it on asphalt, and the history is kept at the Youth Volunteers monument and the Happiness Road memory house on the pass, about 7 km from Dong Van, which became an official tourist site in August 2026.

In the late 1950s the four border districts on the karst plateau, Quan Ba, Yen Minh, Dong Van and Meo Vac, had no motor road to the provincial town; travel up and down the limestone was on foot or by horse. The road was meant to tie the frontier to the rest of the country and to the H’Mong, Lo Lo, Tay, Dao and other communities who lived along it.
Work started on 10 September 1959 at the southern end, near Ha Giang town. When Ho Chi Minh spoke of the project in 1961 he called it the road of happiness, and the name stuck.
The timeline
| When | What happened |
|---|---|
| 10 September 1959 | Construction begins from the Ha Giang town end |
| 1961 | Ho Chi Minh names it the Happiness Road |
| Early 1963 | The road from Ha Giang to Dong Van is nearly complete |
| 1964 | Work pushes on from Dong Van to Meo Vac; a volunteer rope team is formed for the Ma Pi Leng cliffs |
| March 1964 | First recorded death on the rope team |
| Early March 1965 | The rope team’s squad leader is killed days before the end |
| 10 March 1965 | The road reaches Meo Vac and the whole route opens |
Accounts disagree on how long the Ma Pi Leng section took. Some give 11 months for the cliff work itself; others say nearly two years for the whole stretch from Dong Van. Both describe the same thing: the last and hardest piece, done at the end of a job of nearly six years.
How the cliff was cut
Of the roughly 22 km between Dong Van and Meo Vac, the stretches at either end were earth and compacted soil. The middle was solid limestone, and about 2 km of it was sheer cliff with nothing to stand on. That was the job given to the rope team.
More than 100 young volunteers put their names forward, and about 20 of the fittest were chosen. Around two tonnes of rope were brought up. Each worker was lowered down the rock face and hung there for about eight hours a day, driving holes into the limestone with a steel chisel some 30 cm long and a small hammer. A good day was 80 to 100 cm of hole. The holes were packed with explosive and set off by hand with slow-burning fuses.
| What | Detail from the accounts |
|---|---|
| Tools | Steel chisels, hammers, crowbars, picks, shovels and explosives; no machines on the cliff |
| Food | A handful of rice with no maize or cassava mixed in, and dried fish |
| Water | About one cup a day per person for washing, carried up in canteens |
| Illness | Malaria was a constant; workers took quinine and kept smoke fires going at night |
| Scale of the whole road | More than 2 million work-days, about 2.8 million m³ of earth and rock moved |
The people and the cost
The workforce came in two parts. More than 1,300 youth volunteers were sent, many from the lowland provinces of Nam Dinh and Hai Duong as well as the northern mountain provinces, and more than 1,000 civilian labourers came from 16 ethnic groups on the plateau itself. Some accounts give a lower volunteer figure of about 1,200; the order of magnitude is the same.
People died building it, from falls, rockfall, blasting and disease. The memorial on Ma Pi Leng carries plaques for 14 youth volunteers. That is not a full count of the dead: civilian labourers who died are not all recorded by name, and no complete figure has been published.
Where to see the history today
The history of the road is concentrated in one place, the monument site on Ma Pi Leng about 7 km out of Dong Van. It was built with about 37 billion dong from the state budget and public contributions and covers more than 30 hectares.
| What is there | Why stop |
|---|---|
| A 16 m natural stone monument to the youth volunteers | The landmark of the pass and the obvious photograph |
| The Happiness Road memory house | A small exhibition on how the road was built |
| Memorial plaques for 14 volunteers | The names of those who died |
| A 1.5 km trail towards the cliff edge | Views over Tu San canyon; the rock ledge at its end has been closed since 1 July 2026 |
More than 12,000 people visited in 2025, before the site was formally recognised on 2 August 2026. It is also the start of the cliff trail described in our Sky Path guide, and the first of the stops in our Ma Pi Leng Pass guide.
Driving the Happiness Road now
Most of the Ha Giang Loop is the Happiness Road. Highway 4C runs from Ha Giang city over the Bac Sum pass to Quan Ba, through the pine forest to Yen Minh, up onto the plateau to Dong Van and over Ma Pi Leng to Meo Vac, where it ends. The road back to Ha Giang city by way of Du Gia is a different road. The leg-by-leg distances are on our Ha Giang Loop map.
On our three-day Ha Giang Loop you drive all of it over the first two days, and your guide can stop at the monument for as long as you want.

Why is it called the Happiness Road?
Ho Chi Minh called it the road of happiness in 1961, while it was still being built to link the border districts of the plateau with the rest of the country. The name, Duong Hanh Phuc in Vietnamese, stayed.
How long did it take to build the Happiness Road?
About five and a half years, from 10 September 1959 to 10 March 1965. The cliff section over Ma Pi Leng came last and took somewhere between 11 months and nearly two years, depending on the account.
How many people built the Happiness Road?
More than 1,300 youth volunteers and more than 1,000 local labourers from 16 ethnic groups, putting in over 2 million work-days in total.
How many people died building it?
No complete figure has been published. The memorial on Ma Pi Leng names 14 youth volunteers, and accounts describe further deaths among civilian workers from falls, blasting and malaria.
Where is the Happiness Road monument?
On Ma Pi Leng Pass, about 7 km from Dong Van towards Meo Vac. The site has a 16 m stone monument, a memory house and parking, and was recognised as a tourist site on 2 August 2026.
Is the Happiness Road the same as the Ha Giang Loop?
Mostly. The Happiness Road is Highway 4C from Ha Giang city to Meo Vac, which is the northern and eastern part of the loop. The return from Meo Vac through Du Gia uses other roads.
