Gombe is placed at the shore of Lake Tanganyika. The forest is verdant and 13 streams run down the escarpment to the sandy beach. The view of the forested slopes touching the steep escarpment is the most appealing one.
In addition to the main attraction chimpanzee, the park is also home to a troop of habituated olive baboon that can usually be found on the lakeshore. There are several other monkey species present, including red colobus monkey, while red-tailed, which are sometimes hunted by the chimps.
