Africa, the second largest continent, is a mix of steamy rainforests, vast grasslands, and arid deserts. It has no long mountain ranges, but is home to the world's largest hot desert, the Sahara, and its longest river, the Nile. The featured area is the central South Atlantic coastal region of Namibia, including the cities of Walvis Bay and Windhoek.
