Travel tips for Vietnam

Vietnam stretches over a long north-south axis, so the climate differs from one region to another and shapes how a trip should be timed. In the north, the best period runs roughly from October to April, with a dry, mild autumn in October and November and a mild spring in March and April considered the most comfortable windows. Winter, from December to February, is cool and often overcast with drizzle in Hanoi, and turns genuinely cold in the mountains around Sapa, where frost is possible. Summer in the north, from May to September, is hot and very humid, with a typhoon season running roughly from July to September that can disrupt Ha Long Bay cruises at short notice.

The terraced rice fields around Mu Cang Chai turn a golden colour in September and October. The centre and the south follow their own rhythms, so it's worth checking the season for each region you plan to visit rather than relying on a single calendar for the whole country. The local currency is the Vietnamese dong (VND), and the main international gateways are Noi Bai International Airport (HAN) in Hanoi and Tan Son Nhat in Ho Chi Minh City. City centres are compact and walkable, though their narrow streets carry heavy motorbike traffic, and crossing the road takes a steady, predictable pace rather than stopping and starting.

Taxis and ride-hailing apps are the more straightforward way to cover longer distances within a city, while longer journeys are arranged by domestic flight, train, private car, shared minibus or organised tour given the distances involved. Sapa is reachable by overnight train or by road, and the Ha Giang loop is typically done by motorbike, either self-driven or with an easy rider. Dress should account for the cooler months and the mountains, where layers matter more than in the cities. Vietnamese is the local language, and street signage in markets and the countryside isn't always in English, which is worth factoring into independent day trips.
