The Maasai Mara National Reserve (MMNR) covers some 1,510 km2 (583 sq mi) in south-western Kenya. It is the northern-most section of the Mara-Serengeti ecosystem, which covers some 25,000 km2 (9,700 sq mi) in Tanzania and Kenya. It is bounded by the Serengeti Park to the south, the Siria escarpment to the west, and Maasai pastoral ranches to the north, east and west. Rainfall in the ecosystem increases markedly along a southeast–northwest gradient, varies in space and time, and is markedly bimodal. The Sand,Talek River and Mara River are the major rivers draining the reserve. Shrubs and trees fringe most drainage lines and cover hillslopes and hilltops.
The terrain of the reserve is primarily open grassland with seasonal riverlets. In the south-east region are clumps of the distinctive acacia tree. The western border is the Esoit (Siria) Escarpment of the East African Rift, which is a system of rifts some 5,600 km (3,500 mi) long, from Ethiopia's Red Sea through Kenya, Tanzania, Malawi and into Mozambique. Wildlife tends to be most concentrated here, as the swampy ground means that access to water is always good, while tourist disruption is minimal. The easternmost border is 224 kilometres (139.2 mi) from Nairobi, and hence it is the eastern regions which are most visited by tourists.
Visiting
Lion
Game parks are a major source of hard currency for Kenya. Entry fees are currently US$70 for adult non-East African Residents and $30 for children. As of July 2011 Entry fees will go up to $80 for adult non East African residents per day staying inside the park. There are a number of lodges and tented camps for tourists inside the Reserve and the Conservation area borders. The tourists/visitors cater for their own expenses, unless previously arranged by their agencies.
Although one third of the whole Maasai Mara, The Mara Triangle has only one lodge within its boundaries (compared to the numerous camps and
