Iguacu Falls (Brazil and Argentina)

Bordering both Brazil and Argentina are the Iguacu Falls, an amazing system of waterfalls featuring the Iguacu River.  This ranks among the major tourist attractions of South America.  It consists of 275 individual waterfalls separated by forested islands.  "It has a total combined width of about 2 miles" (page 50)and "plunges about 237 feet down a series of ledges". "The falls and the surrounding forests and wildlife are protected by national parks in both Brazil and Argentina."  It is accessible by foot on catwalks (elevated walkways) on both sides of the river, by boat or by plane.
