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 two lions terrorized the workers, killing over 130 people before being killed by Col. Patterson. Patterson recounted the story in his book The Maneaters of Tsavo which became the major motion picture The Ghost and the Darkness (1997).
During the World War I (1914-1918) British forces built fortresses along 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 East is generally flat, with dry plains across which the Galana River flows with swampy marshland. Other features include the Yatta Plateau and Lugard Falls.
Flora and fauna
The Park is home to most of the larger mammals, vast herds of dust –red elephant, Rhino, buffalo, lion, leopard, hippos,crocodile, waterbucks, Lesser Kudu, Gerenuk and Hirola. Fauna is dominated by dry grass land and thorny bushes.
It's usually warm and dry. The temperature is fairly constant year round, but the rainfall varies. The temperature ranges from 27-31°C in the daytime and 22-24°C at night. The long rainy season lasts from March to May and the rainfall is usually heavy, making this a bad time for wildlife safaris. The short rainy season lasts from October to December, but the weather during this period is still good enough to go on safari - just expect some afternoon showers. The humidity is high from December through April

The main purpose of a wildlife safari is to see wild animals in their natural environment. Usually tours are booked at travel agencies and tours with mini buses or Jeeps into the park are organized. Walking safaris are offered by several guides along the Galana River too. Its also possible to visit the park on your own but its not advisable on safety reasons and its not sure you will see many animals as only the guides know the places where the animals can be spotted.
Catering is in most cases included in the price of accommodation
In the lodges the prices for soft drinks are about Ksh 150ksh, beer Ksh 350, wine Ksh 400, water is free in most camps. Prices for drinks in the safari vehicles are about same level.
There are many places to stay inside (more expensive) and outside (less expensive) the park. There is a downside to stay outside the park - in the morning when the tour into the park starts and to the meals you have to go through the gate again and that consumes time.
