Serengeti’s great migration has been listed as one of the Seven Natural Wonders of the World. Not only does it offer incredible views of the plains dotted with huge herds of wildebeests, zebras, and gazelles, but the rivers are often infested with large Nile crocodiles lying in wait. Some of the best safari opportunities in the world are found here, across a landscape made up of volcanic grasslands and vast plains interrupted by rocky outcrops, rivers, and forests.
