When to visit
Put aside the Instagram images of Vietnam as a sun-drenched paradise: Hanoi has a winter, and winter nights can be unpleasantly chilly. By contrast, summer (June through August) tends to be tropical, with shirt-drenching heat and humidity. Hit the sweet spot by visiting in April, May, September, or October when crowds are smaller and temperatures are milder. Plan your trip around Vietnam’s National Day, September 2, to see parades and fireworks.
Getting around
Walking is the best way to explore the Old Quarter. If you opt for a cyclo (pedicab), agree on the price and route first. Metered taxis, private drivers, or ride-hailing services like Gojek, Grab, or Be are the easiest way to cover ground: Two wheels are faster than four.
Hanoi’s shiny new metro is of no use to travelers, while buses tend to be slow. Don’t ride a motorbike unless you’re licensed and experienced. From Ho Chi Minh City, Hanoi is a 2-hour flight.
Traveler tips
Hanoi ’s signature dish is perhaps bun cha, char-grilled pork and rice vermicelli noodles served with tangy broth, pickles, and leafy greens. Follow in Anthony Bourdain’s footsteps at Bun Cha Huong Lien, the French Quarter eatery where he dined with Barack Obama, or try it at Bun Cha Restaurant on 74 Hang Quat, a stone’s throw from Sword Lake (Hoan Kiem Lake).
