Makgadikgadi Pans National Park is part of the Kalahari Basin and has some of the largest salt pans in the world. The shimmering, cracked crust doesn’t look as if it could support any form of life. After good rains, however, this desolate landscape transforms when new grass attracts thousands of animals, and from December to March the park is home to one of Africa’s biggest zebra migrations. As the pans fill up, flocks of pelican and flamingo settle in as well.
