Wow is the word for the Iguazu Falls - 275 waterfalls along over 2km of the Iguazu River with borders on Argentina, BRazil and Paraguay. Amazing especially the Garganta del Diablo one which is huge. The falls are bigger than Niagara falls. Stayed in a cool hostel which was more like a resort and had lovely few days. Huge pool and big gardens so perfect for chilling.... although that is all I seem to do these days! Next stop Brazil baby!
