The green season offers varied viewing, although the forest is at its resplendent best, full of butterflies and wildflowers. It’s a photographer’s dream, as the haze which is often prevalent during other times of the year, is gone, leaving the air clear and bright. The chimps continue to feed mainly on grasses, leaves, and whatever fruit they can find, though the lowland Ilombo vine fruit comes into its own in December attracting big chimp parties. Their daytime siestas tend to take place in tree nests rather than on the ground and the meetings between group members are theatrical and impressive. The lake is clearest in these months often with breathtaking views of the mountains of the Congo in the distance. February can be especially hard to locate the chimps as they follow their primary food source into the higher reaches and thicker parts of the forest so be prepared for more challenging trekking.
