The Makgadikgadi Pans, once an ancient super lake larger than Switzerland, now lies saline and empty – a huge expanse of glistening whiteness – the largest salt pan in the world. During the summer green season, it plays host to the second largest zebra and wildebeest migration in Africa and the shallow flooded pans offer seasonal breeding conditions for an abundance of flamingos and other water birds. Other highlights include giant baobab trees over 1,000 years old, semi-habituated meerkat clans, quad bike expeditions into vast areas of nothingness, and the opportunity to walk with the indigenous San Bushmen and discover how they survive in such a hostile environment.
