The Kalahari is the world's largest expanse of sand, an ocean of wind-sculpted dunes spanning parts of Botswana, Namibia, South Africa and beyond, and covered by savannah, a predominantly grassy landscape dotted with the occasional tree. A completely different ecosystem and habitat, with unique inhabitants such as desert-adapted black rhinos, black-maned lions, meerkats, roan antelopes, blackbucks and tsessebes. Don't miss the elusive aardvarks, aardwolves, caracals, pangolins and porcupines. It's a must-see destination for travellers enchanted by the desert, and of course, with a taste for adventure.
