The optimum time to go chimpanzee trekking in Rwanda is during the rainy season, even though gorilla trekking may be done at any time of year. It is during the month of November when witnessing the chimps is the most rewarding experience. Because of the abundance of foliage, chimpanzees do not have to travel far in order to forage, making them easy to track down.
In November, Uganda experiences a brief rainy season, and although the gorillas’ pathways may be muddy and difficult, they tend to descend down the mountain toward the plentiful food sources. This may shorten the journey to locate gorillas, as well as reducing the length of time spent in the rain.
