What visitors say
We stayed two nights at the campsite, and along with the aforementioned mammals and birds, we also saw plush-crested jays, red-rumped caciques, scaly-headed parakeets, pale-breasted thrushes and boat-billed flycatchers.
We got soaking wet, which is part of the fun. (We were told to bring a change of clothes and they handed out dry-bags to keep our stuff in, like my camera and our shoes and phones.) You'll also see a marauding band of fearless coatis having a feeding frenzy over a bag of potato chips (or something).
I had no idea that Iguaçu/Iguazu Falls straddled a border between two countries or that their name was spelled differently, depending on the side of the border.
We chose a private tour and it meant that in one day we were able to do the helicopter tour, explore Iguaçu Falls by foot, do a waterfall boat tour and also visit the Parque das Aves (Bird Park).
