Ta Xua: cloud seas above the Da River

Ta Xua is a Hmong commune on a mountain range above 2,800 m on the edge of Son La. It is known for seas of cloud at dawn and for a narrow ridge called the dinosaur spine. The views depend on the weather of the previous night, and the roads up are steep, so this is a place to plan with care.

What Ta Xua is like

Ta Xua sits on the Son La side of a range that runs along the border with Tram Tau, which belonged to Yen Bai province until Yen Bai was merged into Lao Cai in 2025. The highest point is given as 2,865 m. Since 1 July 2025 the commune of Ta Xua has absorbed its neighbours Lang Cheu and Hang Dong, and the district of Bac Yen below it no longer exists as a unit; the old district town is now part of Bac Yen commune.

The draw is the view. After a cold, clear night, cloud settles in the valleys and the ridges stand above it like islands. Reports put the clearest chances between about 4 and 6 in the morning, with cloud sometimes lingering on the ridge until about 10. The dinosaur spine, a narrow grassy crest about 15 km from the commune centre and 5 km from Hang Dong, is walked on a trail of about 1.5 km. Other named viewpoints include the lonely tree, a wild plum on a hill that people photograph at sunset, and rocks known as the dolphin, the turtle head and the camel.

The commune is small. VnExpress counts about 20 homestays and guesthouses, no large hotels, and a capacity of 700 to 800 visitors at a time. Above about 1,500 m there are Shan tuyet tea trees more than a century old, and above 2,600 m mossy primeval forest. It is a farming community first, and many viewpoints are on or next to fields.

How many nights

Plan on at least one night on the mountain. The views happen at dawn, and VnExpress advises against arriving in the evening, so the usual pattern is to arrive in daylight, sleep in Ta Xua, and be at a viewpoint before sunrise. The source budgets about 1.5 to 2 million VND per person for two days and one night.

Two nights double your chance of a cloud sea, which depends on the weather and cannot be booked. A trek to the summit area is a bigger undertaking: the Vietjet Air travel guide describes a route of 15 to 18 km, often done over three days and two nights from the Tram Tau side, with more than half of it along cliff edges.

When to go

MonthsConditionsFor you if
October – NovemberCloud season begins; cool, often clearYou want clouds without the deepest cold
December – MarchMost cited months for cloud seas; highs 14–19°C, nights 9–10°C or lowerYou can handle cold nights
AprilEnd of the cloud seasonYou accept a lower chance of a cloud sea
May – SeptemberRainy season; slippery trails and landslide risk on the access roadYou are flexible and watch the forecast

Sources differ slightly: VnExpress and VietNamNet give October to April for cloud hunting, while an older VnExpress piece republished by Bac Ninh state media names December to March. The chance is higher after a cold night that follows a sunny day. Check the forecast and be ready to wait a morning.

Getting there, and the road up

From Hanoi the usual route heads north-west to Son Tay, crosses the Red River at Trung Ha, follows Highway 32 to the Thu Cuc junction and then Highway 37 through Phu Yen to the old Bac Yen town. From there the final climb to Ta Xua is steep. VnExpress reports that the main road to the commune centre is now concrete and that 16-seat vehicles reach the commune, but side roads are narrow, steep and winding with drops on both sides.

Overnight limousine vans from Hanoi were reported at about 700,000 VND return, leaving around 22:00 and taking about five hours with stops. Motorbikes can be hired in Ta Xua; if you are not a confident mountain rider, the same source suggests a local motorbike taxi, with the price agreed first. Read the roads and weather page before deciding to ride.

Road and weather risks

On 10 August 2024 a landslide of about 50,000 cubic metres came down at Km13+600 on Provincial Road 112 in Ta Xua village, burying 20 bungalows and other buildings, killing one person and injuring two, and cutting the road. The provincial authorities then advised tourists to limit visits to Ta Xua during the rain and flood season.

In the rainy season

From May to September, check whether the road is open on the day you travel, avoid driving after dark, and do not stay in buildings directly below cut slopes during heavy rain. The trails turn slippery and the trek routes are prone to landslides in June to September.

In the cloud season the risks are cold and fog. Nights on the ridge are cold, the source on camping notes that there are no restaurants or services on the mountain, and camping on the peak itself needs experience of difficult terrain. Fog can reduce visibility on the road to a few metres in the early morning, which is when people drive to the viewpoints.

Who should skip Ta Xua, and when

  • Travellers with only one day. You cannot be on the ridge at dawn without sleeping there.
  • Anyone uneasy with heights or steep, narrow mountain roads with open drops.
  • Visitors in the rainy season who cannot change their dates if the road is closed or the forecast turns.
  • Groups expecting hotel comfort. Rooms are homestays and guesthouses, often unheated, and space is limited at holidays.
  • Inexperienced riders planning to hire a motorbike for the climb.

Common questions

Questions readers ask

Is a cloud sea certain if I go in the cloud season?

No. It depends on the previous night’s weather. Cold nights after sunny days give the highest chance. Two nights improve your odds.

Can a normal car reach Ta Xua?

VnExpress reports that the main road to the commune centre is concrete and that 16-seat vehicles reach it. Side roads to some viewpoints and homestays are steeper and narrower.

Do I need a guide for the dinosaur spine?

The short walk of about 1.5 km is done without a guide by many visitors in dry weather. The multi-day trek to the summit area is different: sources advise going with a guide and porter and not alone.

What happened with the 2024 landslide?

On 10 August 2024 a large landslide on Provincial Road 112 in Ta Xua killed one person, injured two and closed the road. The province advised limiting visits during the rain and flood season.
