The Amazon Rainforest, or the Amazon Jungle, spread across nine countries in South America is a wondrous sight, if only for its size. Most of the forest lies in Brazil and Peru and it is a haven for some of the most exotic animals and plants known to mankind, as well as several indigenous tribes; there is speculation that there may be several other tribes who have had no contact with the rest of humanity. Canoeing through many forest rivers is the most popular tourist activity in the Amazon.
