The Iguazu Falls are a real wonder of the world, they are located in the Iguazu National Park at the meeting point of the Parana and Iguazu Rivers, on the border between Brazil, Argentina and Paraguay, and are an impressive sight of cascades of water cascading from a height of 72 m up to 3 km wide. The noise of the waterfall is heard over many kilometers, and huge whirlwinds of spray create a rainbow of extraordinary beauty.
