Vietnam is long and thin, 1,600 kilometres from top to bottom, and the differences between north and south are significant enough to feel like two countries. Hanoi has French colonial architecture, misty lakes, and Old Quarter streets unchanged for a century. Ho Chi Minh City is louder and faster. Ha Long Bay and Hoi An sit between them as two of Southeast Asia's most iconic stops.
The food changes as you move through the country: pho in the north, banh mi and broken rice in the south, the white rose dumplings and cao lau of Hoi An in the middle.
