Considered by many to be Kenya's finest game reserve, the 650sq miles of the Masai Mara adjoin Tanzania's well known Serengeti, forming one ecosystem. The open rolling savannah grassland of the Mara is the home of numerous wildlife species including elephant, rhino, lion, cheetah, leopard, hyena, jackal, buffalo, eland, topi, impala, gazelle, warthog and zebra. From June to September, the annual Wildebeest migration takes place when thousands of these animals sweep across the plain and seek out new grazing areas.
