The Serengeti is a huge area of grassland in Tanzania, Africa. Once a year, in the time of drought, about two million herd animals like antelopes travel north to feed and mate before moving south again, when plants there begin to blossom.
Tanzania's Serengeti Plains are the landscape we picture when we think of Africa. For millions of years, the drama of survival has played out here and once a year, millions of antelope migrate across this vast grassland to reach fresh pastures and mate.—Tom Daly
