Tanzania's smallest national park is located on the northwestern side of Lake Tanganyika. Gombe Stream Park is well-known for its chimps. Jane Goodall established a behavioral research program here in 1960, which is now the world's longest-running study of its sort. The chimps have become used to human visits.

The 'Panthood' cry, an enthusiastic whoop, emerges from deep within the forest, quickly joined by a dozen more voices, increasing in volume, pace, and pitch to a frenzied screeching crescendo. The well-known 'panthood' call is a bonding rite in which participants identify one another by their distinctive vocal stylisations.

This spine-chilling cry is also an indicator of approaching visual contact with man's closest genetic cousin, the chimp, to the human listener travelling through the ancient forests of Gombe Stream.

You will require at least two days. Because Gombe Stream National Park is not a zoo, discovering the chimps might take some time. You must be patient in order to see them; a one-day visit is insufficient. We recommend visiting the park for two days.
