North VietnamMiền Bắc

The Red River (Sông Hồng) carries red-brown silt from Yunnan to the Gulf of Tonkin, and its delta is one of the most densely farmed landscapes on earth. Dikes, some a thousand years old, hold the river above the fields; villages sit on slightly higher ground, each with a communal house (đình) and a pagoda.

Hanoi grew on the river's right bank where the dikes and lakes made a defensible site. Most of what a visitor eats in the north — rice noodles, fish sauce, pork, herbs — comes from this plain, which is why the city's food is cheap and fresh.

The delta is also why winters feel raw: a flat, humid plain under grey monsoon cloud from December to March, with drizzle rather than rain.

A belt of limestone runs from southern China through the north: drowned by the sea it becomes Hạ Long, Bái Tử Long and Lan Hạ bays; on land it rises as the towers of Ninh Bình's Tràng An and Tam Cốc, and in the far north as the Đồng Văn plateau of Hà Giang.

The same rock explains the caves, the sheer cliffs and the absence of surface water on the plateau, where Hmong farmers plant maize in pockets of soil between stones. It also explains the travel pattern: every karst area is two to seven hours from Hanoi, and each is better with a night than as a day.

The mountains are home to many of Vietnam's 53 recognised minorities: Hmong, Red and Black Dao, Tày, Nùng, Thái, Giáy, Lô Lô and others, with their own languages, textiles and markets. Around Sa Pa and in Hà Giang, many villages now combine farming with homestays and guiding.

The fairest way to visit is through that local economy: a guide from the village you walk through, a homestay run by a family, handicrafts bought from adults. Markets such as Bắc Hà (Sunday) and Đồng Văn remain trading events first and sights second.

The Lý dynasty moved the capital to Thăng Long (Hanoi) in 1010; for most of the next eight centuries the north was the political centre, fighting off Chinese and Mongol invasions — twice at the Bạch Đằng River near today's Hạ Long. The Nguyễn moved the court to Huế in 1802, and the French made Hanoi the capital of Indochina.

After 1954 the north became the Democratic Republic of Vietnam; Điện Biên Phủ in the far north-west was the battle that ended French rule. The American War brought bombing to Hanoi and Hải Phòng. Since 1976 Hanoi has been the capital of the unified country, and the north remains the seat of the Party and the state.

Keep one bed in Hanoi and make trips from it. The water-karst trips (Ninh Bình, Hạ Long or Lan Hạ) are two to three hours away; the mountains (Sa Pa, Hà Giang) five to seven. Link the mountains in one loop rather than two out-and-back trips.

Weather sets the order: October–November suits everything; March–May is second best; summer brings storms that cancel cruises and landslides that close mountain roads; winter brings fog and cold to the mountains. Keep a spare day before any international flight.
