During the time from November to February is the cold season in Bac Kan with the temperature is often below 0 degree C, therefore the scenery looks very gray and unattractive.
The hot and wet season runs from April to October with almost all rainy days, so tourists in Vietnam tours won’t have chance to visit outdoor destinations which are some of the most fascinating aspects of Bac Kan such as Ba Be National Park or ATK. It also rains heavily, reaching Bac Kan by buses and other vehicles is more difficult.
