Our tips
Public holidays
If you visit Vietnam during the week-long Tet holiday, you should be aware that almost all activities, such as shops, restaurants and tourist sites, will be closed. It’s a good idea to find out in advance which places are open to tourists. As far as transport is concerned, the days before and after the Tet holiday see frequent traffic jams as workers return to the big cities.
Clothing
If you’re planning to spend a week or several days exploring northern Vietnam, there’s no need to pack too much clothing. Temperatures are fairly even from one region to the next. Just remember that the mountains are cooler than the plains, especially in winter.
For a trip to Vietnam from Saigon to Hanoi, or vice versa during the months of December to February, pack clothes for two seasons. While the North, in mid-winter, experiences cool, cold days, the South (Ho Chi Minh City and the Mekong Delta) enjoys a dry, hot climate, with temperatures between 23°C and 33°C. This is the ideal season to discover this region. Don’t forget to pack clothes suited to these two contrasting climates.
