Adventurer Bear Grylls shows you how to survive in Ecuador's extreme environments. Ecuador has part of the Andes mountain range, huge high-altitude cloud forests and part of the mighty Amazon Jungle. Bear paraglides onto the edge of the Andes and follows rivers into the jungle to bring him face to face with huge colonies of Spear Nosed bats, giant Weevil grubs and vicious Piranha. Bear builds a bamboo bridge and a bow and arrow to catch fish. But it doesn't all go his way — he's forced to ride the rapids of the Amazon on a single tree trunk.
