Between July and October, more than two million ungulates migrate from the Serengeti National Park in Tanzania to the Maasai Mara National Reserve in Kenya. The movement of these animals - mainly made up of wildebeests - is the largest of any in the world.
Called one of the "Seven New Wonders of the World," the great wildebeest migration takes place on the 40,000 square kilometers that make up the Serengeti Ecosystem. Zebras, gazelles and eland often join in on the migration, moving with the herd to find food and water. Those on a Kenya and Tanzania safari  will likely encounter this mass traveling across the continent.
The migration, altogether, is a cycle that begins with the January birthing season for wildebeest cows at the southernmost point of the animals' range. As the grasses of the Serengeti dry out around March, the clockwise quest for sustenance begins. The entire geographical cycle measures about 500 kilometers.
The kicking up of hooves is not the only activity that occurs during the migration. Herds are followed by a host of predators, including lions, hyenas, cheetahs, leopards and others that follow the cycle just as much as the herds do.
The preying continues at Maasai Mara Reserve, which boasts one of the highest lion densities in the world.
