The crocodile infested Lake Turkana has the triple honour of being Kenya's largest lake, the world's largest desert lake and the world's largest alkaline lake. It occupies 6,405 sq km, and stretches for 250 km lengthwise. The rivers Omo, Turkwel and Kerio feed it, but except for evaporation it lacks an outlet.

Lake Turkana carries the world's largest Nile crocodile numbers, 60 fish species and over 350 bird species. Its shores are the dwelling place of the Turkana and El Molo people - a people undeterred from their traditional lifestyle by the allures of western civilization.
