Tsavo West together with its expansive Tsavo East neighbor combine to equal a massive 4% of Kenya, forming one of the largest national parks in the world. The park is home to the Big Five, but wildlife viewing can be a bit slow at times. There are, however, several landmarks worth visiting including Mzima Springs with its underwater observation chamber for close-up views of hippos, recent lava flows and a rhino sanctuary.
It is safe to swim in the sea and swimming pools, but it is not recommended to do so in lakes, rivers and open reservoirs as they may be infested with bilharzia parasites. Drinking water from these places is not advisable. Tap water is safe to drink unless otherwise indicated.
Tsavo West is best visited in the dry months from June to October and January to February, the same as Tsavo East. Although the park can be visited any time of year, wildlife viewing during the height of the Wet season (November, April and May) is not recommended. The vegetation is dense in the wet months, making it more difficult to see animals, which tend to spread out anyway due to the abundance of water.
