Time has passed, but the memory of the war still lives on in the hearts of the Vietnamese people. Their pride and their grief remain, and will be remembered both at home and around the world.
That is why we created the DMZ Vietnam tour — for anyone who wants to understand our country and its people, in the spirit of President Ho Chi Minh’s words: “The country of Việt Nam is one, the Vietnamese nation is one. Rivers may run dry, mountains may erode, but this truth shall never change”
DMZ Vietnam Overview
What is the DMZ? DMZ stands for Demilitarized Zone. Vietnam’s DMZ ran along the 17th parallel in Quảng Trị province, following the Bến Hải River out to the Gulf of Tonkin, with a buffer of roughly 5 miles (8 km) on either side where no troops from either government were permitted.
It was established after the 1954 Geneva Conference, which ended the First Indochina War between the French Union and the communist-led Việt Minh. Vietnam was provisionally split into two zones: the Democratic Republic of Vietnam in the north, led by Hồ Chí Minh from Hà Nội, and the State of Vietnam (later the Republic of Vietnam) in the south, based in Sài Gòn.
The division was meant to be temporary, pending national elections — but war broke out between North and South in 1955, and the DMZ hardened into a de facto border for the next two decades.
From 1965 to 1973, millions of American and allied troops were deployed to support South Vietnam against the North, and the DMZ area itself saw heavy fighting despite its official “demilitarized” status — by January 1968, North Vietnamese and Việt Cộng forces in the zone were estimated at over 40,000 troops.
The DMZ ceased to exist when Vietnam was reunified: Sài Gòn fell on 30 April 1975, and the country was formally reunited as the Socialist Republic of Vietnam on 2 July 1976 — 22 years after the line was first drawn.
Hiền Lương – Bến Hải River
Once as quiet and peaceful as any other place in central Vietnam, Hiền Lương – Bến Hải became world-famous once the river was chosen to mark the dividing line between north and south.
Under the Geneva Agreement, the DMZ was drawn along the Bến Hải River, extending no more than 5 km on each side of the demarcation line. Its purpose was to act as a buffer and prevent renewed fighting — for over two decades, neither side was permitted to station troops within it.
Over time, the Bến Hải River became less a military boundary and more a symbol of national division — and, later, of reunification.
When the country was split, the two sides painted a white line just 1 cm wide across the middle of the bridge to mark the boundary. Though it should have been a link between the two halves of the country, Hiền Lương Bridge instead became a symbol of division.
For more than twenty years (1954–1975), this area witnessed constant psychological warfare between north and south — from loudspeaker broadcasts blasted across the river to competing propaganda campaigns, each side trying to outdo the other.
Vịnh Mốc Tunnels
This underground village is a striking example of the tunnel systems built in Vĩnh Linh district. Vịnh Mốc itself sits on a basalt-and-sand bluff by the sea.
During the war against the United States, the village served both as a frontline outpost of the north and as a supply depot — for nearly 2,000 days and nights, its residents lived underground, refusing simply to endure the bombing. Instead, they organized themselves to fight back, moving food, ammunition, and medicine to support the resistance.
Beyond the DMZ sites covered here, there are plenty of interesting things to do in Quảng Trị worth exploring if you have extra time in the province.
Quảng Trị Citadel
The Citadel and the town of Quảng Trị were later honored as a “Heroic Fortress” by the government — a title paid for by the sacrifice of thousands of soldiers and civilians who fought and died to defend it.
Today, green grass covers the Citadel grounds, but it grows over ground once soaked in the blood of those who defended it — as the saying goes here, “every square meter of turf was paid for with a meter of blood.”

The tour also takes in Tà Cơn airfield and the old Khe Sanh battlefield along the historic road linking Vietnam to Laos, along with other historic sites such as the Rockpile and the Hồ Chí Minh Trail.
The Rockpile is a solitary rock outcrop just north of Route 9. Its location is so inaccessible that, during the war, it could only be reached by helicopter.
Hồ Chí Minh Trail
The Hồ Chí Minh Trail was a vital north–south supply route, used by North Vietnamese forces to move troops, weapons, and provisions to their fighters in the south.
It was never a single path, but rather a shifting network of trails spread across a wide swath of jungle terrain, often weaving in and out of neighboring Laos to avoid detection.
Khe Sanh Battle
A symbol of the resilience and skill of the Vietnamese army and people against the far more heavily armed American military.
Tà Cơn Airfield was once a key American airstrip and a frequent target during the war. As General Võ Nguyên Giáp famously put it: “Every citizen is a soldier, every village is a fortress” — from the youngest to the oldest, everyone in this region took part in resisting American forces to protect their villages.
