7. Iguazú Waterfalls – Brazil & Argentina
You have to be there personally if you want to grasp the magnitude of these massive natural forces. The Iguaz Falls, located on the border between Brazil and Argentina, are one of the world’s largest waterfalls. Water at a rate of up to seven million liters per second cascades down the almost three-kilometer-long cliff. Wear waterproof gear if you wish to get fairly close to the waterfalls through the bridges and footbridges!
