Regarded as the Eden of Africa, Gabon is one of the most biodiverse countries on the planet – home to gorillas, chimpanzees, crocodiles and forest elephants. With 80% of the country covered by almost impenetrable rainforest, much of Gabon remains unexplored. On this expedition, Steve and the team head into a remote part of the Moukalaba Doudou National Park. Cut off from the outside world by the Doudou mountains, this ‘unknown zone’ has never been explored… until now. Teaming up with local jungle guide Ghislain Bouassa and primatologist Alessandra Mascaro, Steve hopes to discover whether this unexplored jungle could be home to an undiscovered population of chimpanzees. The local Punu community relate tales of a mythical canyon – a place where they believe the river disappears off the face of the earth. They hold it sacred and have never ventured beyond the canyon, but they have given Steve their blessing to explore it for the first time – to discover what animals are in the jungle beyond.
