When is the best time to visit Virunga National Park?
As Virunga is located on the equator, the temperature remains roughly the same (hot and humid) throughout the year. The notable difference is between the rainy and non-rainy seasons.
Ironically enough, the best time to enjoy clear blue skies (particularly for photography purposes) is during the rainy months (April, May, October and November), as it can get quite foggy during the dry season.
The good news is that it rarely rains for a full day, and the periodic spatters actually make way for beautifully clear viewing conditions.
