Lake Baringo is, after Lake Turkana, the most northern of the Kenyan Rift Valley lakes, with a surface area of about 130 square kilometres (50 sq mi) and an elevation of about 970 metres (3,180 ft).
The lake is fed by several rivers, Molo, Perkerra and Ol Arabel, and has no obvious outlet; the waters are assumed to seep through lake sediments into the faulted volcanic bedrock.
It is one of the two freshwater lakes in the Rift Valley in Kenya, the other being Lake Naivasha.
It lies off the beaten track in a hot and dusty setting and over 470 species of birds have been recorded there, occasionally including migrating flamingos. A Goliath heronry is located on a rocky islet in the lake known as Gibraltar.
