Ngorongoro Crater is the largest unbroken collapsed caldera with 610 meters deep, 20 kilometers in diameter, and covers an area of 311 sq. km. Spectacular as it is, the crater accounts for just a tenth of the Ngorongoro Conservation Area. The crater is home to many species of wild game and birds, with the exception of impala and topi (due to fierce competition with the wildebeest) and the giraffe (because there is not much to eat at tree level), almost every species of African plains mammal lives in the crater, including the endangered black rhino. One surprising thing is that the crater elephants are mainly bulls. With all these attraction the Crater is the ultimate destination
