Iguazu Falls is actually a series of 270 waterfalls flowing out of the Iguazu River, which serves as a de facto border between Brazil and Argentina. A World Heritage Site, some of the individual falls reach 269 feet in height, though the majority are only 210 feet. The most impressive of the waterfalls is the Devil’s Throat, a 2300-foot-long cliff that discharges as much as 45,000 gallons of water per second.
Towering over Niagra, the only waterfall in the world that rivals Iguazu is Zambia’s Vic Falls. Whereas Iguazu is wider — because it’s composed of many falls — Vic Falls is the largest single curtain of falling water in the world.
