Tan Uyen and Than Uyen: tea hills and the Muong Than field

This is the gentler, lower side of Lai Chau. Highway 32 leaves the mountains of the pass and drops into broad valleys planted with tea and rice. Around the former Tan Uyen town, the provincial portal describes tea hills along the highway covering nearly 2,000 ha, with plants 40 to 50 years old; they are a popular backdrop for photographs.

Further on, around Than Uyen, the valley opens into the Muong Than field. A local saying ranks the four great fields of the north-west as “nhat Thanh, nhi Lo, tam Than, tu Tac”: Muong Thanh in Dien Bien first, Muong Lo second, Muong Than third and Muong Tac fourth. Press reports give Muong Than more than 2,000 ha of rice. Road 279 runs along the field past the old communes of Muong Kim and Phuc Than.

The field is flat paddy, not terraces. For terraces, go up the side valleys: a 2024 report describes nearly 200 ha at Ta Mung, and more than 400 ha at Ta Leng near Pu Ta Leng. Outside the two main moments of the year, the landscape is green or bare, and the valleys are pleasant rather than remarkable.

Two windows matter. Farmers start transplanting in May, when water is led into the fields and the terraces reflect the sky; a 2024 handbook calls April to May the water-filling season. The rice turns yellow in September and October, when harvesting begins. The exact week shifts every year with the weather and differs between the valley floor and higher terraces.

Two harvest reports note that Than Uyen also grows a winter-spring crop, harvested around May, so the valley can show yellow rice in late spring as well. Check local reports before you fix dates.

The fields are workplaces. Walk on the bunds between plots, not across them, and single file where they are narrow. At harvest, threshing happens beside the paddy and the road; keep out of the way of machines and of rice drying on the tarmac. Drones are common among photographers here, but ask before flying low over people working, and keep clear of houses.

Farmers sometimes ask for a small fee to walk on or photograph in a private field, especially at harvest. Ask, and keep to the bunds.

• Travellers whose dates fall between the two windows, if rice is the reason for the trip: from November to March the fields are bare.
• People expecting high terraces like those of Mu Cang Chai: Muong Than is a flat valley field.
• Anyone with only one day in Lai Chau; the pass and a village make a better use of it.
• Summer travellers on a fixed timetable, when rain can slow the mountain roads in and out.
