Cruisers to Halong Bay can make the journey to Hanoi, the cultural and political capital of Vietnam, if they won't have time to see the city before or after their cruise. A trip there is a multilayered journey through buildings that date from the French colonial era to the imposing Ho Chi Minh Mausoleum. If you have time, take in a water puppet show at the Thang Long Theater. Or sit in a café in the Old Quarter and sip a glass of traditional Vietnamese coffee after shopping for handicrafts. Hanoi is proud of its arts, crafts and cuisine—three things you'll be able to experience, even on a short visit.
