Wildebeest migration in southern Serengeti, Tanzania. Pictures can't convey the awesome spectacle of various herds migrating, slowly converging with other herds on their way towards their eventual destination, the Mara River in Kenya. We stopped and soaked in the movement of tens of thousands of these animals over the course of almost an hour. By the time they reach the Mara around late summer, they will be a million strong. Zebras also join the migration. This annual event is the last great large animal migration in the world.
