2. Top things to do when visiting Pu Xai Lai Leng
2.1. Conquer Pu Xai Lai Leng Peak
Conquering this peak takes about 1.5 hours along an 800-meter trail that weaves through ancient sa mu and po mu forests, moss-covered trunks, and lush ferns. Sunlight pierces the dense canopy in golden beams, and occasional clearings reveal layers of cloud-wrapped mountains. The old-growth forest blends tropical and temperate flora, both evergreen and deciduous. At the summit, trekkers are greeted by a vast sea of white clouds - a reward as majestic as the climb itself.
2.2. Visit Buoc Mu Village
Surrounding the base of Pu Xai Lai Leng are 17 Hmong villages, with Buoc Mu Village standing out with over a century of history. While sharing many traditions with neighboring communities, Buoc Mu retains its own unique character. Weathered wooden houses, tinged with the patina of time, evoke a mysterious beauty. Beneath each roof lies a hidden world shaped by generations, preserving age-old customs and stories. A visit here invites tourists to experience authentic highland life, where architecture, culture, and hospitality blend seamlessly into an unforgettable encounter.
2.3. Check out border marker 422
Just 200 meters away from the peak of Pu Xai Lai Leng lies border marker 422, a symbolic point marking the boundary between Vietnam and Laos. The trek from the mountain base to the marker takes around 1.5 hours, including rest stops. It offers the same immersive experience through lush forest scenery as the route to the peak. Reaching this spot rewards hikers with sweeping cross-border views.
2.4. Paddle an inflatable boat on the Nam Khien River
At the foot of Pu Xai Lai Leng flows the tranquil Nam Khien River, a picturesque waterway that invites tourists to explore by inflatable boat. Paddling along its gentle current offers a refreshing contrast to the mountain trek, allowing you to drift past lush riverbanks, listen to the soft rustle of the forest, and enjoy the cool, clear water.

3. How to get to Pu Xai Lai Leng?
The journey to this mountain often begins in Vinh, the former capital city of Nghe An. The most straightforward route is National Road 46A - National Road 46B - National Road 7A. National Road 7A will eventually lead you to Na Ngoi Commune. Here, make your way to Na Ngoi Border Guard Station to present your ID and register for the climb.
The journey continues along a border patrol road for about 18 kilometers past Buoc Mu Border Guard Post to the mountain base. Although this border patrol road has been paved, it is steep and prone to landslides, with loose rocks, soil, and fallen branches scattered along the way.
Follow this road for another 10 kilometers. Eventually, heavy erosion forces tourists to get off the bike, trek for 5 kilometers, then climb roughly 2 kilometers to border marker 422. Another 200 meters and you will reach the summit of Pu Xai Lai Leng at 2,700 meters high.
4. Best time to visit Pu Xai Lai Leng Mountain
The best time to trek Pu Xai Lai Leng is during the dry season from November to April, when rainfall is minimal and the trails are safer from landslides. Between December and March, the mountain becomes a paradise for cloud hunters, with the added chance of seeing frost and ice in December. For nature lovers, March and April are especially enchanting as rhododendron flowers bloom, painting the slopes in vibrant colors. The rainy season from May to October is not recommended due to heavy rains, slippery paths, and safety risks.
