Ecuador

Grylls paraglides onto the edge of the Andes and follows rivers into the Ecuadorian jungle, is attacked by huge colonies of spear-nosed bats[disambiguation needed], and observes giant weevil grubs and piranhas. He builds a bamboo bridge and a bow and arrow to successfully catch fish, but it doesn't always go his way and he's forced to ride the rapids of the Amazon on a single tree trunk.
