Puerto Iguazú is definitely a place for tourists. Foz Do Iguaçu has some life of its own: If the tourist season is low, there are still other businesses. Puerto Iguazú clearly lives only for tourism: Travel agencies, souvenir shops, bars, hotels, hostels, restaurants… That’s it.
As a town, I definitely preferred Foz Do Iguaçu. But we all know that people come here for the waterfalls so, which side is better, Argentina or Brazil?
Well, both should definitely be visited. Brazil provides the panoramic sights, but the magnificence of these waterfalls is better seen in Argentina!
