Tsavo National Park was established on 1 April 1948 with an area of 21,812 km². It is the largest park in Kenya. In May 1948 Tsavo National Park was divided into East and West for administrative purposes. The two Parks are divided by Nairobi–Mombasa railway/road.
The Waliangulu and Kamba tribes used it as a hunting ground prior to gazettement. Dr. Krapf journeyed on foot through this area in 1848 crossing the Tsavo river on his way to Kitui – first European to see Mt. Kenya. Construction of the railway reached Tsavo river in 1898. During the construction of the bridge, lions (man-eaters of Tsavo) terrorized the workers, killing over 130 people before being killed by Col. Patterson. During the World War I (1914-1918) British forces built fortresses along the Tsavo River to counter threats from invading German forces from Tanganyika (present Tanzania) – whose intention was to blow up the Tsavo River Bridge that was vital to British communication. Captain Lugards, a European explorer, passed through the area on his way to Uganda and had a drop over at the Lugards falls area.
Tsavo West is characterized by a hilly arid landscape. This park is dotted with volcanic cones; dramatic, black lava flows; and a number of rocky outcrops.
