The Best Time To Visit Gombe Stream National Park is during the dry season, from June to October. During this period, chimpanzees are more active and easier to spot, as they forage for food in the forest. Additionally, the dry season offers excellent hiking conditions and clear views of Lake Tanganyika. However, the park can get crowded during peak tourist season, so visiting during the shoulder months of November to May can provide a more tranquil experience.
