The Maasai Mara National Reserve (also spelled Masai Mara; known by the locals as The Mara) is a large game reserve in south-western Kenya, which is effectively the northern continuation of the Serengeti National Park in Tanzania. It is named after the Maasai people (the traditional inhabitants of the area) and their description of the area when looked at from afar: "Mara", which is Maa (Maasai language) for "spotted," an apt description for the circles of trees, scrub, savanna, and cloud shadows that mark the area.
It is famous for its exceptional population of Big Cats, game, and the annual immense migration of zebra, Thomson's gazelle, and wildebeest from the Serengeti every year from July to October, known as the Great Migration.
All members of the "Big Five" (lion, leopard, African elephant, African buffalo, and Black Rhinoceros) are found in the Maasai Mara. The population of Black rhinos was fairly numerous until 1960, but it was severely depleted by poaching in the 1970s and early 1980s, dropping to a low of 15 individuals. Numbers have been slowly increasing, but the population was still only up to an estimated 23 in 1999.
Elephants, Hippopotami and Nile crocodiles are found in large groups in the Mara and Talek rivers. Leopards, hyenas, cheetahs, jackals, and bat-eared foxes can also be found in the reserve. The plains between the Mara River and the Esoit Siria Escarpment are probably the best area for game viewing, in particular regarding lion and cheetah.
