Lung Cu flag tower is a 33.15 m octagonal tower on Dragon Mountain, about 26 km north of Dong Van, flying a 54 m² national flag close to Vietnam’s northernmost point. From the lower car park it is about 839 steps to the top, the last stretch a spiral stair inside the tower; an electric shuttle cuts out much of the lower climb. It opens from 08:00 to 17:00.
The tower is a 2010 monument on a site with a much older story. The reason to go is the view from the top over the valleys, the Lo Lo and H’Mong villages below and the hills across the border.
Reach Lung Cu by 08:00, before the day’s crowds
A private car, a mountain driver and a licensed local guide, starting from Dong Van so you are at the gate when it opens.

The present tower was completed and inaugurated in September 2010. It has an eight-sided base about 20 m tall, decorated with reliefs in the style of Dong Son bronze drums showing scenes from Vietnamese history, topped by a flagpole of about 13 m. The flag measures 9 by 6 m, 54 m², one square metre for each of the country’s 54 official ethnic groups.

The older story
Tradition holds that a flag has marked this hill since the Ly dynasty in the eleventh century, when troops planted one to mark the northern frontier. The modern history is plainer: a simple wooden pole went up in 1978 and was replaced several times, a concrete tower was built around 2000, and the site was listed as a national monument in 2009 before the present tower was built.
The climb
The steps come in three stages: a long run of stone stairs up the hillside from the lower car park, a shorter run to the base of the tower, and the spiral stair inside it to a small viewing platform. Take the whole climb at an easy pace and it takes 25 to 40 minutes up, with rest points on the way.
The electric shuttle runs from the lower car park up the first steep section and drops you much closer to the tower, leaving a couple of hundred steps plus the spiral stair. For older travellers or anyone with knee trouble, the shuttle is the difference between a hard climb and a manageable one. The stair inside the tower is narrow and turns tightly; people who dislike enclosed spaces can stop at the base, where the view is almost as good.
Allow about an hour and a half for the visit, including the shuttle, the climb, time at the top and the walk down.
The view and the villages
From the top you look down on a wide, cultivated valley ringed by limestone peaks, part of the Dong Van Karst Plateau. In spring and summer it is green with rice and maize; from late October the terraces turn gold and patches of pink buckwheat appear. The hills to the north are in China.
Lo Lo Chai
At the foot of the hill is Lo Lo Chai, a village of the Lo Lo people with earth-walled houses and stone yards. In October 2025 UN Tourism named it one of its Best Tourism Villages, and many of its houses now run homestays. The Lo Lo are one of the smallest ethnic groups in Vietnam, and their women’s clothing, with bright appliqued panels, is unlike anything else on the loop.
H’Mong villages
H’Mong families farm the slopes around the valley. From the tower you can see their scattered houses and the stone walls around fields, the same pattern you will have passed all the way from Yen Minh.
The real northernmost point
The flag tower is a symbol, not the country’s actual northern tip. That lies about 3.3 km further north in a straight line, at a rocky promontory on the Nho Que River in Seo Lung hamlet, where the border follows the middle of the river. Getting there means around two hours on footpaths through fields and forest.
In 2018 a viewpoint pavilion with a coordinates sign was built about a kilometre short of the true point, and many people photograph it believing they are at the tip. Both are further than most loop itineraries have time for. If you want to reach either, it needs a half day of its own; tell us before you book.
When to go and how Lung Cu fits the loop
Lung Cu is a dead-end detour north from the main loop road, adding roughly 50 km there and back. That is why some itineraries skip it. Ours both include it, at different times of day.
| Trip | When you are there | Why |
|---|---|---|
| 3-day loop from Ha Giang city | Day 2, 08:00 | Straight from Dong Van as the gate opens; quiet, and the valley is often clearing from mist |
| 4-day trip from Hanoi | Day 2, about 16:00 | Late light on the valley before the night in Dong Van old quarter |
Weekends and Vietnamese public holidays are much busier than weekdays, and the platform at the top is small. Clear mornings are most common from September to November; in December to February fog can cover the valley completely. Both trips return to Dong Van, whose old quarter is the night stop. The rest of the route is in our Ha Giang Loop guide.
Entrance and shuttle tickets are included in both of our trips.

How many steps are there at Lung Cu flag tower?
About 839 from the lower car park, including the spiral stair inside the tower. The electric shuttle takes you past the first steep section and leaves a couple of hundred steps plus the tower stair.
What are the opening hours of Lung Cu flag tower?
08:00 to 17:00 every day, including weekends and holidays. Arriving at opening time is the best way to avoid the crowds.
How much does Lung Cu flag tower cost?
The entrance ticket is 25,000 VND (~$1) per adult and the optional electric shuttle is 15,000 VND (~$1) per person. Both are included in our trips.
Is Lung Cu the northernmost point of Vietnam?
Close to it, not at it. The true northernmost point is about 3.3 km further north on the Nho Que River, around two hours away on foot.
How far is Lung Cu from Dong Van?
About 26 km, around 45 minutes by car. It is a dead end, so you come back the same way towards Dong Van or on to the Vuong palace.
Can older travellers manage the climb?
Most can with the shuttle, taking the steps slowly with stops. The inside stair is narrow; the base of the tower has almost the same view for anyone who prefers to stop there.
