The Makgadikgadi Pan is the world’s largest salt pan, formed on the bed of an ancient lake that began evaporating aeons ago. Visiting Makgadikgadi is a unique desert experience: in the dry season, this vast expanse of sun-baked salt glistens in the light and when the rains come, the pan is home to a cornucopia of flamingos and other waterbirds, as well as one of Africa's biggest zebra populations, whose annual migration is a wonder to behold.
