Tanzania’s oldest and most popular national park is also a world heritage site and was recently proclaimed a 7th worldwide wonder. The Serengeti is famed for its annual migration when some six million hooves pound the open plains as more than 200,000 zebra join the wildebeest’s trek for fresh grazing. The herds travel throughout the calendar year clockwise through the Serengeti-Mara ecosystem. The peak viewing seasons are in the dry periods of January-March in the Southern Serengeti, when the herds gather to calve and the predators slink around looking for young prey and then again July-October in the north (and into the Masai Mara on the Kenyan side of the Serengeti-Mara ecosystem) when the herds brave the steep banks and watchful crocodiles as they cross the Mara and Talek rivers. Yet even when the migration is quiet, the Serengeti offers arguably the most scintillating game-viewing in Africa: great herds of buffalo, smaller groups of elephant and giraffe, and thousands upon thousands of eland, topi, kongoni, impala and Grant’s gazelle.
