Foz do Iguacu or Iguacu Falls is a magnificent array of waterfalls which are located in Southern Brazil in the state of Parana on the border between Argentina and Brazil.

They stretch for 2.5 miles plunging 269 feet into Iguacu River.

They are an absolutely dazzling sight which must be seen.

There are numerous rocky and wooded islands on the edge of the escarpment over which the Iguacu River plunges. There are 275 separate waterfalls or cataracts.

The name of the falls comes from the Guarani Indian word meaning "great water."

In 1986 Iguacu Falls were declared a Natural Heritage of Mankind by Unesco.
