Skip the elephant place (so crowded and contrived - see elephants in the wild instead) and the Giraffe center (total rip off) and go instead to see Kibera. It will change your life. Freddy and Martin are amazing - so warm, so passionate about being ambassadors for the place they have called home their whole lives. They will show you one of the largest slums in the world from an insider's point of view (they even welcomed us into one of their homes so we could see how people live - fascinating!) We saw several community projects - a school, power women collective for women with HIV who are selling crafts, biofuel from human waste, jewelry from bones rather than ivory. All so interesting and the people were incredible - so inspiring. Of course, we gave a donation and this is part of the point, but we were not pressured to do so at all. We bought some jewelry made by the power woman and bone workmen - inexpensive and really unique and I wear mine all the time. We also gave a donation to the school. But what Freddy and Martin are most interested in is changing the world's perception of the slum by showing people what it is really like. You will be remembering this place for a long time after your visit. The community spirit is infectious.
