Very few people are privileged enough ever to track gorilla and chimpanzee in the rainforests of Uganda and Rwanda. A face-to-face encounter with these endangered great apes in their natural habitat is a truly astounding experience. Perhaps it is the fact that they are our closest living relatives that makes getting up close to them so moving and awe-inspiring. Perhaps it is the fact that their very existence is under serious threat. We may be among the last generations ever to have the chance to breathe the same air as these highly intelligent, sociable and elusive animals.
