Iguazú Falls

Iguazú Falls is a system of 275 individual waterfalls spread across a crescent of the Iguazú River on the Argentine–Brazilian border, collectively forming the widest waterfall complex in the world during peak flow. The Argentine side of the national park provides elevated walkways directly above many of the falls, including the Garganta del Diablo — the Devil's Throat — a U-shaped chasm where fourteen of the falls converge into a continuous roaring curtain of white water visible in its full width only from a boat. The surrounding subtropical Atlantic Forest supports over 400 bird species.
