The Central Kalahari Game Reserve is one of the world's largest game reserves. It dominates the centre of Botswana and it is Africa at its most remote and esoteric; a vast sand sheet punctuated by a few huge open plains, occasional salt pans, and the fossil remains of ancient riverbeds. The game is often sparse and can seem limited, with no elephants or buffalo; the distances are huge, along bush tracks of variable quality and it has relatively little scenic variation. There are subtle changes between its different landscapes, but there isn't the variation here that you'll find around Chobe or the Okavango. Because of this, the animal species found here vary little from area to area. The birdlife here is very varied, with Africa's largest bird, the ostrich, doing particularly well. The kori bustard are the world's heaviest flying birds and are also common, stepping around the plains in search of insects and small reptile and mammals. You will also find korhaans as it's the area's most obvious birds. Game viewing anywhere in the central Kalahari area can be a stark contrast to the amazing densities of game that can often be seen in the Okavango. The big game is here, but occurs in very low densities - as you'd expect in such a harsh, arid environment. Springbok and oryx are probably the most numerous in the park.
