The best time to visit Vietnam is the dry season, which lasts from October until April. There are also differences in climate between the north and the south of the country. The winters are cold and misty in the north, while the south enjoys hot, humid weather almost all year round. Head for the north between September and November, when the temperatures are pleasant, while the best time to visit the south is between December and April. Leave in search of a unique civilization set in a superb landscape.
