The best time for a safari in Kenya, Uganda, Tanzania, and Rwanda is during the dry seasons (June to October and December to February), when wildlife viewing is at its peak. In Kenya and Tanzania, the Great Migration (July–September) sees millions of wildebeest crossing the Mara River, while January–February offers calving season in the Serengeti. For gorilla trekking in Uganda and Rwanda, the dry months (June–September & December–February) provide easier hiking conditions and clearer trails. While the wet seasons (March–May & November) bring lush landscapes and fewer tourists, heavy rains can make roads muddy and animals harder to spot. For the ultimate safari experience, aim for June, October, optimal for wildlife sightings and adventure.
