A visit to the Iguaçu Falls is a must on many travellers' itinerary of South America. And for good reason - they are incredible. You can view the falls from both Brazil and Argentina, and each side provides quite a different experience. We were staying in Puerto Iguazu, which is in Argentina, and we visited both sides from this point. It's equally easy to base yourself in Foz do Iguaçu, Brazil, which is a much bigger city. Brazil: getting there The border crossing between Argentina and Brazil was very straightforward. We decided to use the hostel-organised transfer instead of going independently, which would have meant three buses and a lot of time-wasting. So we crossed by car and didn't even have to get out - we passed our passports to our driver Susanna, who gave them to the border guards. They were stamped and we were in - possibly the easiest border crossing ever, although the Brazilian stamps are incredibly boring. Brazil: Pros and cons When we arrived, we realised that we didn't have any real, and apparently none of our credit cards were suitable for use. We withdrew cash at the ATM with no problems though. It cost R$37, which seemed a fair price to us. For more information visit:
