Stretching around 360,000 square miles across Botswana, Namibia and South Africa, the Kalahari Desert is not a desert in the strictest sense of the word. The desert is part of the 970,000-square-mile Kalahari Basin, which includes the Okavango River Delta and other wetter areas.The Central Kalahari Game Reserve is a vast flat expanse of scrub-covered fossil dunes between ancient river valleys it has a fascinating spectrum of very different plants and animals. With the rains (Nov-April), the desert comes to life, with hordes of plains game followed by numbers of predators, producing some of the best summer wildlife viewing in Botswana. Nxai Pan and Tau Pan were the first safari camps to be built in their respective areas and offer an unprecedented opportunity to experience truly pristine wilderness areas and a complete contrast to the lush wetlands of the Okavango Delta.
