At the edge of Nairobi National Park is the Animal Orphanage, home to orphaned, sick or problem animals from all over Kenya. Where possible, the animals are rehabilitated and released back into the wild. The best time to visit is at 2:30 pm, which is feeding time. Built in 1963, some of the concrete enclosures are a little cramped, but recently the Kenya Wildlife Service has been replacing these with more spacious and more natural-looking compounds. The Safari Walk is a fairly new addition to the orphanage; a raised boardwalk with interesting information plaques about the flora and fauna takes you around the animal enclosures. Daily 8:30 am-5:30 pm. US$5. Langata Road, at the headquarters of Kenya Wildlife Services, Nairobi. Phone 500-622. http://www.kws.org.
