One of Tanzania's best kept wildlife secrets is the Ruaha National Park. Ruaha's unusually high diversity of antelope is a function of its location. Ruaha is well known for its varied dramatic scenery, which includes rolling hills; large open plains; groves of skeletal baobabs and along its southern border, the Great Ruaha River, from which the park gets its name. This is by far the most dominant geographical feature of the park and, for the wildlife it is the most important. Ruaha has a hot, dry climate which means the animals don’t tend to stray too far from dependable water sources. This makes predicating game movements far easier particularly in the dry season.
