Combined with Tsavo East, Tsavo West National Park forms Kenya's largest game sanctuary. Tsavo West covers a huge variety of landscapes, from swamps and natural springs to rocky peaks, extinct volcanic cones to rolling plains and sharp reddish outcrops. Tsavo West National Park is situated on Kenya's southern border with Tanzania, located about 200km south east of Nairobi. Combined with Tsavo East, this park forms one of the world's largest game sanctuaries. The East and West parks are separated by the Mombasa/Nairobi road, and both work nicely on a circuit with Mombasa.

Tsavo West has a variety of landscapes, from swamps and natural springs to rocky peaks, extinct volcanic cones, to rolling plains and sharp reddish outcrops. Wildlife can be difficult to spot because of the dense scrubs. In May 1948, a month after its conception Tsavo National Park was divided into East and West for administrative purposes. At 21 812 square km, Tsavo National Park is the largest park in Kenya. Named after the Tsavo River which flows from west to east, the park is considered one of the world's biodiversity strongholds. It is the only Kenyan park that permits night drives and also allows off-road driving so one can see the wildlife close up.
