Everyone we know who has been to Iguazu told us we'd be crazy to miss it, and honestly, they were right.
Iguazu falls is...well...maybe you should just watch this video:
It's a true natural wonder.
The falls straddle the border between Argentina and Brazil. It's one of the widest falls in the world, and the sheer amount of water that cascades down it is impressive to behold. Each side sets you up for an awe-inspiring and unique view, so it's definitely worth it to see both if you can.
We started our first day in Iguazu by exploring the Argentina side.
On the Argentinian side, which has a more elaborate trail system and (as the header of this section implies) tons of wildlife to see. Because they're pretty used to people on the trails, they aren't at all afraid and get close, hoping for a handout.
One of our favorites was the Coati, which is basically the raccoon of South America. The locals were constantly shooing the Coati away - they weren't nearly as impressed with the critters as as we were.
We also encountered swarms of beautiful, multicolored butterflies everywhere in the park. They, too, were accustomed to humans and would flutter all around the viewing decks, making brief pit stops on people's arms and hands.
Later, we took the walkway out across the Iguazu river to reach the top of the falls.
Eventually, we found ourselves peering down the biggest, roaringest part, La Garganta del Diablo (Devil's Throat).
Over to Brazil
The next day, we crossed the border into Brazil and took the walkway out into the center of the falls for a good strong misting and some incredible rainbows.
