Ah... the famous Serengeti. Finding the animals is much harder here since they have much more room than in the other parks, but on the same note, the viewing is arguable the most "natural." The Park is 5,700 square miles and is part of the 9,600 square mile Mara-Serengeti ecosystem. It is home to an estimated 1.5 million (yes, that's MILLION) wildebeest, 500 thousand Thomson's and Grant's gazelles, 200 thousand zebras, etc.
