Iguazu Falls is located where the Iguazu River tumbles over the edge of the Paraná Plateau, upriver from the Iguazu's confluence with the Paraná River...Numerous islands along the long edge divide the falls into numerous separate waterfalls and cataracts, varying between 200 ft and 269 ft high. The number of these smaller waterfalls fluctuates from 150 to 300, depending on the water level. About half of the river's flow falls into a long and narrow chasm called the Devil's Throat (Garganta do Diabo in Portuguese).
The junction of the water flows marks the border between Brazil, Argentina, and Paraguay.The border between Brazil and Argentina runs through the Devil's Throat. On the right bank is the Brazilian territory, which has just over 20% of the jumps of these falls, and the left side jumps are Argentines, which make up almost 80% of the falls.
There is a walkway along the canyon with an extension to the lower base of the Devil's Throat and helicopter rides offering aerial views of the falls are available.
