The Iguazu Waterfalls are among the most amazing waterfalls on the planet. Do not underestimate the time you need here – allow at least 1/2 day for the Brazilian side and at minimum a full day for the Argentina side. These falls are spread between the Brazil and Argentina border and extend up the Rio Iguacu several miles. The only similar waterfalls in comparison are Victoria Falls on the Zambezi River between Zambia and Zimbabwe. The massive Victoria Falls are more or less oriented in a straight line while the Iguacu Falls are at different levels and heights.
