Bossou

Bossou is a small settlement in southeastern Guinea, situated at the western foothills of the Nimba Mountains close to the tri-border point where Guinea, Liberia, and Côte d'Ivoire meet. The surrounding landscape forms part of the transboundary Nimba Mountains Biosphere Reserve, a UNESCO-protected area of exceptional biodiversity. The site gained international recognition in primatology through decades of field research on a local chimpanzee community observed using stone tools to crack nuts — a behavior documented here with unusual consistency. For travelers, Bossou serves as a remote gateway to the Nimba highlands.
