Since most of the Iguassu Falls are in Argentina, they are best seen from the Brazil side and experienced from the Argentinian side. This means you have to waste a fair amount of time with the border crossing and changing money. The Argentinians will only accept pesos for the admission fee to their side of the national park, no credit cards. Our tour stopped at an efficient gift shop with rip-off rates to get the job done expeditiously. The Friendship Bridge that crosses the Iguassu River is painted green and gold (Brazil colors) half way and blue and white (Argentina colors) on the other. A short drive took us to an overlook where we could also see Paraguay in the distance.
We hiked down to the river and boarded boats for one of the wettest rides we've had in a long time. It was like driving into a hose. Some people dressed in bathing suits, more than appropriate for this hot, sunny day. The boat drivers took us under the falls repeatedly, causing their passengers to shriek with delight.
Then we walked about a mile on a boardwalk over the rushing river currents to Devil's Throat. You might think that building a mile of walkway would detract from the views of the falls, but they are so huge, the people admiring them were blips on the radar. We stood within inches of the swirling, cascading torrents.
Lastly we took a train through the park to another walkway which allowed us to stroll over more falls to a panorama of falls half way across the river. Again words are inadequate to describe the views we had today. It had us wondering why we had not come here sooner. The amount of water that passes through here every day is unimaginable. And it only comes from the drainage of northern Brazil. The Amazon and glacial melt from the Andes are not involved. If we had another day here, the largest hydroelectric dam in the world is worth a visit. But it's time to finally head home.
