Demarcated in the north by the Kenyan border and in the south by Maswa Game Reserve, lakes Eyasi and Manyara and by Tarangire National Park, it includes Serengeti National Park and the Ngorongoro Conservation Area. To this we have added the northern mountain circuit – Arusha National Park, Mount Meru, Mount Kilimanjaro, Mkomazi and the Usambara Mountains.
The Serengeti The Serengeti plays host to the annual migration. With an elevation of between 900 and 1800m, an annual temperature range of between 21°C and 27°C and a precipitation range of 950 to 1150mm, the area’s climate – in normal years – is temperate and experiences a bimodal rainfall pattern, with the short rains occurring in November and December, the long rains in March – May. The Serengeti is not blessed with large numbers of permanent water sources: the migration follows the rain, its quest good grass and high quality water.
