The Iguassu Falls are often heralded as the most beautiful falls in the world. Vastly larger than Niagara with its 275 different cataracts and 3-mile spread, the mighty, 266-foot high Iguassu crashes thunderously between Brazil and Argentina’s lands, 269 feet into the Iguassu River. Sun and water vapor often create rainbows over the falls, which becrown this beautiful landscape. Take in the stunning panorama the Brazilian side’s viewing platforms offer, or head over to the Argentina side to witness “The Devil’s Throat,” a gargantuan, 262-foot high, 49-foot wide horseshoe-shaped gorge that plummets into the river with a deafening roar. Zodiac trips also offer a closer experience of the falls from the river below, allowing visitors to even pass behind them.
