Lake Turkana, formerly known as Lake Rudolf, is located in the north of Kenya. It is the world's largest largest alkaline lake. The small town of Loiyangalani is located on the southeastern coast of the lake. The region is hardly visited by tourists. The temperature is usually high and life is hard, but the area with volcanic rocks is beautiful and there still live fascinating authentic tribes such as the El Molo and Turkana. Loiyangalani was the setting for John le Carré's novel 'The Constant Gardener' and it was also the location for the movie.
