Among the Herds of the Great Migration

The Serengeti in Tanzania and the Maasai Mara in Kenya, reached through Kilimanjaro or Nairobi airports, stage the largest land migration on Earth. More than a million wildebeest move in vast columns with zebra and gazelle, trailed by lions and hyenas. During calving season the southern Ndutu plains fill with newborn calves by the hundred thousand. Calving peaks January through March, and the great herds mass along the Mara River from July through October. The herds themselves are reliably present in season, but a river crossing is luck and never promised.
