Chyulu Hills N. Park
The Chyulu Hills National Park, which follows the spine of the geologically recent Chyulu Hills lava ridge – only formed around 500 years ago – and shares a border with Tsavo West to the south, is one of Kenya's least visited and least developed national parks. Aside from the wildlife and the glorious scenery (the hills cook the role of the less impressive Ngong Hills for the filming of Out of Africa), the main attraction is Leviathan Cave, the world's second-longest lava tube. You can explore Leviathan from Umani Springs lodge in Kibwezi Forest.
Wildlife in the Chyulus is fairly sparse because of the altitude (I500-2160m), but the plains between the highway and the hills are often speckled with game, including giraffe, buffalo, eland, zebra, and wildebeest. In the glades of the forested hills themselves, you may spot elephant and giant forest hog.
The crest of the Chyulus is wreathed in mossy cloud forest, constantly watered by the clouds that make the landscapes here so ravishingly beautiful. On a clear day, the haloed peak of Kilimanjaro rises to the west.
