Sa Pa

Sa Pa is cool all year, and its weather changes by the hour. September to November is the favourite season: the terraces turn gold before the harvest, usually in September, and the skies are often clearer. March to May is mild, with fruit trees in blossom, and in May and June the terraces are flooded for planting and mirror the sky. Summer, from June to August, is warm, green and wet, with heavy afternoon rain, leeches on the trails and occasional landslides. Winter, from December to February, is cold and frequently foggy, with temperatures near or below freezing; in some years it snows on the town and Fansipan, which brings crowds of Vietnamese visitors. Hotels have heaters, but bring warm clothes. Weekends and Vietnamese holidays are much busier than weekdays.

From Hanoi, the Nội Bài–Lào Cai expressway has cut the journey to Sa Pa to about five to six hours by road. Sleeper buses and limousine vans run from Hanoi, and from Nội Bài Airport, directly to Sa Pa. The overnight train runs from Hanoi to Lào Cai station in about eight hours, with private sleeper carriages operated by several companies; from Lào Cai, buses and shared minibuses climb the last 35 kilometres or so to Sa Pa in about an hour. Book train and bus seats in advance at weekends and holidays.

Sa Pa town is compact enough to walk, though it is hilly. Taxis, motorbike taxis and hired cars reach the waterfall, the pass and the villages; hiring a motorbike is possible, but mountain roads, fog, trucks and wet surfaces make it risky unless you're experienced.

• Check visa requirements before you travel; many visitors can apply for an e-visa online.
• Carry cash in dong for homestays, villages and small shops; ATMs are in town but not in the villages.
• Bring layers, a rain jacket and good walking shoes in every season.
• Agree trekking routes, homestay arrangements and prices before you set off.
• The Vietnamese name is written Sa Pa; you'll also see "Sapa" on signs and tickets.
• Mobile coverage is good in most valleys, but download offline maps for treks.
• Expect to be followed by women selling textiles on popular trails; a polite, firm "no, thank you" is fine.

Mountain specialities include grilled meat and vegetables on skewers from the street stalls around the square, hotpot with salmon or sturgeon raised in the cold streams, black chicken, and smoked buffalo or pork. Thắng cố, a stew of horse meat and offal, is a Hmong market dish for the adventurous. Try the local plum and corn wines with care. Cafés in town serve Vietnamese coffee, and many homestays cook generous family dinners.

The town has everything from backpacker hostels to large hotels and resorts, but some streets are noisy with construction, so look for places with views over the valley. Homestays in Tả Van, Lao Chải, Tả Phìn and other villages offer simple rooms or shared sleeping lofts in family houses, often with a home-cooked dinner. Lodges and eco-resorts in the valleys sit somewhere in between.

The best way to understand the region is on foot, walking from village to village with a local guide. Many guides are Hmong or Dao women who grew up on these trails and can explain farming, weaving and family life. Book through your hotel, a licensed agency, or a community-run cooperative or homestay network, so that more of the money stays in the villages, and ask whether the guide holds a licence. Treks in Hoàng Liên National Park, including all routes up Fansipan, require a registered guide and a permit, and guides know which paths are safe after rain.

Vietnam has fifty-four recognised ethnic groups, and the province around Sa Pa is one of the most diverse; more than half the population of Lào Cai belongs to ethnic minorities. The Black Hmong wear indigo-dyed hemp and cotton, dyed in vats of fermented indigo that leave their hands blue. Red Dao women wear red headscarves and often shave their eyebrows and hairline. The Giáy, Tày and Xa Phó live here too, and each group has its own language, festivals and craft traditions. Tourism has brought income and new roads, but also pressure on land and traditions, and many families still depend on rice, corn and cardamom farming.

The national park covers the high ground of the Hoàng Liên Sơn range west and south of Sa Pa, rising from about 380 metres to the summit of Fansipan. It protects montane and cloud forest with rhododendrons, rare conifers and orchids, and is home to the western black crested gibbon and many Himalayan bird species found nowhere else in Vietnam. It is an ASEAN Heritage Park. Stay on trails, carry out your rubbish, and don't buy wild orchids, herbs or animal products sold by the roadside.

Ask before photographing people, and accept a "no"; many villagers simply don't want to be treated as a sight. Don't photograph inside homes or during ceremonies without permission. Children selling bracelets and postcards are a common sight in town and on the trails. Child-protection organisations advise against buying from them or giving them money or sweets, because it keeps them out of school; buy from adults, or support local schools and community projects instead. Dress modestly in villages, stick to paths along the terrace walls so you don't damage crops, choose community-run homestays, and pay fairly for crafts that take weeks of work.
