Iguazú National Park, situated on the international border of Argentina and Brazil, features one of the world’s most striking natural wonders. Iguazú Falls offers a misty and majestic realm of rushing, roaring water with rainbows adorning the cascades, which stretch for nearly two miles. Experience this marvel up close from one of the wooden walkways that stretch out over the river, and be sure to take in the spectacular vista from the giant balcony of the "Devil's Throat." According to ancient myths, a jealous god slashed the Iguazu River (meaning “great water”) in two, creating falls as high as 269 feet. The UNESCO site is bordered by its sister park Iguaçu in Brazil, and the falls are surrounded by the lush Misiones rainforest, so don’t be surprised to see tropical birds flitting about as they search for fish in quieter waters.
