Brazil
Got an early start and managed to beat the crowds twice, not only at the border crossing to Argentina, but also into Parque Nacional Iguazu. Eduard was a great driver/guide, clearly very experienced as he said hi to seemingly half the park employees as he showed me both the lower and upper trails inside the national park. Saved a ton of time too, as a tour guide he was able to cut a lot of the long lines for the little train inside the park that goes from the main viewing areas to the separate viewing area for Garganta Del Diablo, and knew all of the little details about not just the falls but animals and forests.
Eduard's sharp eyes caught not only egrets on the side of the viewing paths/bridges but the great dusky swift perched right next o some of the falls, was very cool. After a half day, ended up at Garganta Del Diablo, where the guides (including him) hang back to let all the tourists crowd the final viewing area. Like the experience from the Brazilian side, the sheer power Iguazu Falls is very clearly in evidence, and being right on top of the falls on the Argentina side is equally dramatic in size and experience. Absolutely worth the time to see both sides of the falls if you can.
As predicted by noon or so we were done (~4 hours actually in the park), and was time to head back to the Brazilian side. With yesterday's foggy weather and a quick border crossing back to Brazil, ended up doing the very affordable shared helicopter ride offered by Helisul on the way back. They keep it affordable by keeping it short, barely 10 minutes long, but the four or so passes you get over the falls is enough to appreciate the tower of spray reaching into the air, the scale of the falls all in front of your eyes at once, and ideally, the sun refracted in the mist kicked up by the falls making a rainbow or two only visible from the air.
Tried to get a few sunset photos before dinner, but with so much water through the falls today (Eduard said average was 2000 or 2200 cubic meters per second, and today was more than 2700 cubic meters per second earlier in the day) there was a ton of mist. And while a few locations on the Brazilian side's trail are okay, particular over San Martin falls, apparently the popular angle is over the Devil's Throat from the multi-level viewing platform. Alas... still tomorrow!
