Serengeti Plains.

From Serengeti National Park, the plains go as far as the western portion of the Ngorongoro around the small Lake Ndutu and Lake Masek to the north of Olduvai Gorge. Wildebeest migration normally makes these plains occupied by the animals, which however leave the area when the long rains arrive and move northward into the Serengeti in May.

Salei Plains.

Stretching westwards from the highland and Craters, the Salei plains which are lower and drier that the Serengeti, remote, harsh and sparsely populated by the Maasai, are only believed to shelter the hardiest and most drought tolerant animals during the dry months because it is always dusty at that moment, it however shelters so many and it comes alive during the rainy season. It is important still to note that the Ngorongoro is made up of a large tract of dry and barren grassland for most of the year, swinging in an arc from Serengeti in the northwest, through the Gol Mountains, to the Salei plains in the northeast.

Around Ngorongoro Crater: Engaruka.

Situated just outside the Ngorongoro at the foot of the eastern escarpment, Engaruka, a mysterious ruined city of about 500 years, is said to be a long abandoned site that includes remnants of an advanced irrigation system, odd rubbed filled platform and terraced stone houses.
