The Masai Mara National Reserve is the most frequently visited reserve. It is located in the south west of the country and covers an area of over 1500km². Mentioned on the World Heritage list, it is the northern extension of the famous Serengeti Park (in Tanzania) and forms part of its ecosystem.

The reserve is in Masai country and owes its name to the river which crosses it, the Mara. The Masai people, shepherds who have come up from the Nile over the centuries, lead a semi-nomadic existence and, despite contact with the modern world, have preserved their ancestral way of life.

In the infinite spaces of the Masai Mara savannas, hills and marshes, there is a considerable amount of wildlife which is easy to spot: lions, leopards, cheetahs, elephants, buffalo, Grant and Thomson's gazelles, zebras, masaï giraffes, warthogs, hyenas, jackals, hippopotamuses, black rhinos, crocodiles… and numerous species of bird.

Masai Mara is the place where hundreds of thousands of animals escape the dryness of the Serengeti plains at the end of June each year and migrate to the Kenyan savannas.

The interminable lines of gnus, zebras and impalas crossing the river is an unforgettable sight. The animals who take part in this great transhumance return back to Tanzania from the month of October onwards.
