Iguazú Falls

One of the planet’s most awe-inspiring sights, the Iguazú Falls are simply astounding. A visit is a jaw-dropping, visceral experience, and the power and noise of the cascades – a chain of hundreds of waterfalls nearly 1.85 miles (3km) in extension – live forever in the memory. An added benefit is the setting: the falls lie split between Brazil and Argentina in a large expanse of national park, much of it rainforest teeming with unique flora and fauna.
