There are nearly 150 animals at this preservation and rehabilitation site, most of them monkeys, including chimpanzees, gorillas, and other endangered species. There is a new gorilla structure that should soon be completed. There are lots of great touring and educational opportunities at the facility. The staff is extremely impressive and friendly. See the official website for more details and photos, as well as newsletters.
The admission is generally under $2 and all proceeds go toward rehabilitation and an anti-bushmeat campaign.
