At the main gates of Nairobi National Park, this orphan-elephant rescue and rehabilitation program is a must-see for animal lovers. Daphne Sheldrick founded the project in 1977 in memory of her late husband David, a former warden at Tsavo East National Park. The center cares for young abandoned elephants and rhinos and works to release the animals back into the wild. You can commune with these lovable creatures as they frolic in the mud and drink from giant baby bottles. Best of all, your entrance fee helps support the project’s conservation efforts.
