I have just returned from a wonderful trip to one of the seven natural wonders of the world – Iguazu Falls. The falls are shared by the Iguaçu National Park (Brazil) and Iguazú National Park (Argentina) , and have been designated the title of a UNESCO World Heritage Site. The “Iguazu” name comes from Guarani or Tupi words, and means big water. Iguazu Falls resides where the Iguazu River falls over the edge of the Paraná Plateau, some 14miles upstream from the Iguazu’s confluence with the Paraná River. The waterfall system comprises of 275 falls along 1.67 miles of the Iguazu River. Iguazu falls boasts the greatest average annual flow of any waterfall in the world.
