Mzima Springs, situated 48 kilometres from Mtito Andei is in Tsavo West National Park, south of Nairobi, Kenya. Tsavo-West is a semi-dry wilderness, so the occurrence of the springs makes it more remarkable – like a desert oasis. Water springs from volcanic rock, after travelling underground from the Chyulu Hills. The volcanic action occurred 10 kilometres away from the source of the springs less than 500 years ago. Mzima Springs consists of a top pool and a long pool, from with the Mzima River flows to join the Tsavo River 7 kilometres away. The Chyulu Hills are composed mainly of volcanic ash and lava.
