Kenya's largest park, Tsavo, is sliced in two: Tsavo West and Tsavo East. Together these parks comprise four percent of the country's total area and encompass rivers, waterfalls, savannah, volcanic hills, a massive lava-rock plateau, and an impressive diversity of wildlife. Midway between Nairobi and Mombasa, Tsavo East is famous for photo-worthy sightings of large elephant herds rolling and bathing in red dust. The palm-fringed Galana River twists through the park providing excellent game viewing and a lush counterpoint to the arid plains. Other highlights here include the Yatta Plateau, the world's longest lava flow; Mudanda Rock; and the Lugard Falls, which spill into rapids and crocodile-filled pools.
Tsavo West is wetter and topographically more varied, with some of the most beautiful scenery in the northern reaches of the park. Highlights here are Mzima Springs, a series of natural springs with large populations of hippos and crocodiles; Chaimu Crater, a great spot for seeing birds of prey; and Ngulia Rhino Sanctuary. Wildlife is not as easy to see in Tsavo West because of the denser vegetation, but the beautiful scenery more than compensates.
