The Serengeti National Park is Tanzania's largest and covers an area of 14,763 sq Km, roughly the size of the US state of New Jersey. It lies between Lake Victoria to the West, the Rift Valley to the East, and the Kenyan border to the North where it merges with the Masai-Mara National Park.

Meaning 'endless plains' in the Masai language, the Serengeti historically was a grazing ground for nomadic Masai Herdsmen who travelled through the grasslands with their cattle. It was first declared a Game Reserve in 1921 by the British colonial government and later upgraded to a National Park in 1951.

More large mammals coexist here than in any other place on Earth. The Park contains at least two million wildebeest, half a million Thomson's gazelle, and a quarter of a million zebra in addition to hundred of species of other wildlife, bird life and fauna. All the so-called "big five" - elephant, rhino, lion, leopard and buffalo can be found here. Other common species found here include, hippo, giraffe, eland, impala and other types of antelope. Large colonies of Primates such as baboons and monkeys can also be found dotted across the landscape. The numerous rivers that criss-cross the landscape are home to hundreds of crocodiles and other aquatic life forms.

The Africa Game reserve is one of the most enduring images of Africa for non-Africans, of which probably the most vivid is annual migration across the Serengeti. In May at the end of the Rainy Season, herds of animals begin a migration en-masse to the north and West in search of the permanent watering holes. The sight of endless streams of wildebeest, zebras, Gazelles and predators such as lions, cheetah and hyena following in their wake is one of the greatest sights of the natural world. In November as the rains return to the south the migratory surge turns south repeating this great spectacle of nature.

The months following the return south (December to March) are the best for visiting as the animals are concentrated in the southern regions and there is a higher chance of sightings. The average Daytime high temperature is 28o C (81o F), and at night 14o C (57o F). The rainy season is from March to May and again between October and November.
