The Serengeti National Park is widely regarded as the best wildlife reserve in Africa due to its density of predators and prey. The park covers 14,763 km2 (5,700 sq mi) of grassland plains and savanna as well as riverine forest and woodlands. The park lies in the north of the country, bordered to the north by the national Tanzania and Kenyan border, where it is continuous with the Masai Mara National Reserve.

The park is usually described in three regions Serengeti plains, Western corridor and Northern Serengeti. Serengeti plains are characterized by the endless, almost treeless grasslands. This is where the wildebeest breed, as they remain in the plains from December to May. Other ungulates also occur in huge numbers during the wet season. Kopjes are granite florations which are very common in the region, and they are great observation posts for predators, as well as a refuge for hyrax and pythons. The Western corridor the “black cotton” soil covers the swampy savannah of this region. Grumeti river is home to enormous Nile crocodiles, colobus monkey, and the martial eagle. The migration passes through from May to July. The Northern Serengeti landscape is dominated by open woodlands and hills, ranging from Seronera in the South, to the Mara river in the limit with Kenya. Apart from the migratory wildebeest and zebra (which occur from July to August, and in November), the bushy savannah is the best place to find elephant, giraffe and dik dik.

Human habitation is forbidden in the National Park with the exception of staff for TANAPA, researchers, Frankfurt Zoological Society staff, and staff of the various lodges and hotels. The main settlement is Seronera which houses the majority of research staff and the park’s main headquarters, including its primary airstrip.

As well as the migration of ungulates, the park is well known for its healthy stock of other resident wildlife, particularly the “Big Five”. The park also supports many further species, including cheetah, Thomson’s and Grant’s gazelle, topi, eland, waterbuck, hyena, baboon, impala, African wild dog and giraffe. The park also boasts about 500 bird species, including ostrich, secretary bird, Kori bustard, crowned crane, marabou stork, martial eagle, lovebirds and many species of vultures.
