Overview: Venezuela is famous for its “Lost Worlds” – foreboding mountains, huge swamps, and impenetrable jungles - all seemingly cut off in space and time. Yet each is linked, by the waters of a mighty river, The Orinoco. Following the explorers’ journey up the Orinoco from mouth to source, discover a delta haunted by pumas and festooned with Scarlet Ibis; a river that’s home to South America’s largest predator, the Orinoco Crocodile; Los Llanos – the swampy realm of the world’s largest rodent and its numerous predators and a tropical jungle home to hallucinating shamans and tarantula-hunters.
