During the a few short months at the beginning of each year, the second biggest migration of zebra and wildebeest (and the only one in southern Africa) occurs at the Makgadikgadi Pans; the edge of Botswana's Kalahari. You can safely assume that few others have also heard about this spectacle and it remains a deliciously well-kept secret for now. At this time of the year, the desert landscape turns lush and green under the dramatic thunder-clouds, and thousands of animals gather from the arid south to feed. Very often there will be predators and scavengers in attendance, and very few other people. In terms of wildlife, this is the absolute best time to visit the Kalahari.
There are some simply unique camps here that are worth visiting in themselves, or you can think about joining the herds on horseback for a truly exhilirating experience.
