The Devil's Gorge, fed by the river Iguazu, is a stunning waterfall which serves as a barrier separating 2 national parks, one of which is in Argentina and the other in Brazil. Arboreal and bushy species can be found in the area, some of which are in danger of extinction; and animals such as the jaguar, the puma and tapir live in the forest along with a variety of vertebrates and invertebrates. This guide and map of the site are accompanied by a DVD.
