West Ongamo

North of Kilimanjaro, the high mountain gives way to open grasslands used by pastoral communities. Ongamo-speaking people inhabited parts of Kilimanjaro's northern slopes, where oral traditions remember hunting, the gathering of honey and fruit, and the keeping of cattle. Their language belongs to the Maa group, linking their history to other communities of the East African plains as well as to the cultivated mountain slopes.

The later city of Nairobi lies here.
