Lung Cu Flag Tower

Lung Cu is where the Ha Giang loop reaches the top of Vietnam. A tall stone flagpole stands on Dragon Mountain, near the border with China, flying a very large national flag whose area is often quoted as 54 square metres, one for each of the country's ethnic groups. The tower is reached by a staircase usually described as around 140 steps, and from the top the view takes in the plateau, the patchwork fields of nearby Lo Lo Chai and the ridgelines beyond the border. Nearby are Lo Lo Chai village, with its old stone and earth houses, and Lung Cu Commune, whose fields are a popular spot for photographs in the flowering season. The trip is a detour from Dong Van, so it is included in some, but not all, loop itineraries.

What to do there. Park or arrive by tour vehicle, buy an entrance ticket at the base if one is needed, and climb the steps at your own pace. The staircase is steep but short, and the viewing platform is usually busy on clear days. The flag itself is dramatic in wind, and the sense of standing at the edge of the country is the main attraction.

Down below, a small cluster of cafes and stalls sells snacks and souvenirs, and the road back to Dong Van passes more of the plateau's rock gardens and small farms.

Lo Lo Chai and the flowers. A short walk or ride from the tower is Lo Lo Chai, a village of the Lo Lo community, known for traditional houses and for fields of colour in the flowering season. In autumn, buckwheat blossoms in pink and white attract many photographers, and in spring peach and plum blossom can appear.

The village also has homestays, which is why some travellers choose to stay overnight in the area rather than riding back to Dong Van. Dress modestly, ask before taking pictures of residents, and buy food or crafts directly from local families.

Practical points. Lung Cu is roughly 25 kilometres from Dong Van, and the round trip is one reason three-day tours sometimes drop it. The four-day easy rider tour linked here includes Lung Cu, the Ma Pi Leng Pass and the Nho Que boat, which makes it a good choice if the flagpole is a priority.

Visibility is best on clear mornings, as mist can shroud the summit. Wear layers, because the tower is exposed and can be windy and cold. Bring cash for the entrance and refreshments, and be mindful of the border area, where photography near military posts may be restricted.

Fitting Lung Cu into your plan. The detour from Dong Van takes time, so decide in advance whether you want it. On a three-day tour it is often an optional extra, or it is dropped to make space for the Ma Pi Leng crossing. On a four-day tour it fits comfortably into the second morning.

If you are riding yourself, give it a half day, and set off early to reach the tower in clear light. If cloud rolls in, wait a while, since conditions can change within half an hour. Combine the visit with a wander through Lo Lo Chai and a meal in the area before returning.
