The dry season at Mahale Mountains National Park (May to October) is widely regarded as the best time for chimpanzee trekking. With less rainfall, clearer trails, and chimps that tend to stay at lower elevations, this is when Mahale is at its most accessible and rewarding.
Why Dry Season?
During the dry months, the forest canopy thins slightly and the undergrowth is less dense, making it easier to spot chimps and follow them through the forest. The chimps also tend to concentrate near fruiting trees at lower altitudes, reducing trek times considerably.
Lake Tanganyika is at its calmest during the dry season, making boat transfers from Lagosa airstrip to the park smoother and more comfortable. The water visibility is excellent for snorkelling, with up to 20 metres of clarity on good days.
What to Expect
Daytime temperatures hover around 28°C at the lakeshore, dropping to a pleasant 18–20°C at night. Morning treks typically start at 7am, when the chimps are most active. Afternoons are free for water activities, relaxation, or optional forest walks.
Packing Essentials
Even in the dry season, Mahale’s forest can surprise you with a sudden shower. Pack a lightweight rain jacket, sturdy hiking boots with good ankle support, long trousers (for forest treks), and plenty of insect repellent. A good pair of binoculars will enhance your chimp viewing significantly.
