Lake Magadi is located in the southern Kenyan Rift Valley. It is easily reached in a day trip from Nairobi. The lake provides the world's largest source of soda.

Lake Magadi is located 100 km southwest of Nairobi and 20 km north of the Tanzanian border. In this area the Rift Valley is a narrow graben 60-70 km wide. Further south the rift valley changes to a broad depression.

Lake Magadi tilapia (Oreochromis alcalicus grahami) are able to survive in temperatures of 42.8 deg C and in an alkaline environment. Fish have been observed gulping air. Aerial respiration is a means to obtain extra oxygen in the low partial pressure pools.
