When to go to Hanoi & Ha Long Bay

A thousand years of history around a lake, with the best pho in the country.

Hanoi's Old Quarter still runs on French-colonial facades and streets named for the guilds that once worked them, all navigated by an unbroken river of scooters. Most visitors add on an overnight boat through the limestone karsts of Ha Long Bay a few hours east.

How long to stay

4–6 days is the sweet spot.

Flight time

About 20h from the US East Coast, 11h from Europe, 5h from South Asia.

Good to know

  • Cross the street at a steady, predictable pace — scooters flow around you, stopping confuses them.
  • Book an overnight Ha Long Bay cruise (not a day trip) at least a few weeks ahead in high season.
  • Bargain gently at Dong Xuan and the Old Quarter; opening offers are usually inflated for tourists.
