Katavi National Park lies south of the Mahale Mountains on a high flood plain surrounding Lake Katavi. It is one of the most difficult Parks to reach and is strictly for those of an adventurous spirit, but it has excellent game viewing with a real wilderness atmosphere. July to October are the best months to visit the Park. The water of the Park shelters crocodile, hippo and large flocks of pelicans. The diverse woodland, acacia bush, lakes and swamps have attracted over 400 species of birds. Leopard, lion, elephant, eland, roan and sable antelopes, southern reedbuck and topi inhabit the short grasses and thickets. Kitavi is also home to one of the largest herds of buffalo, with as many as 1,600 animals.
