The nice thing about traveling to the border is to enjoy a varied and typical cuisine of each country. Even better if it is where Argentina, Brazil and Paraguay meet.
Whoever goes to Foz do Iguaçu has the opportunity to visit 3 countries in one day or in three – like I did. When the rivers Iguaçu and Paraná meet it is possible to see the Brazilian, Argentinean and Paraguayan flags, each one in its own country. My main reason for going there was to see the waterfalls and the nature. As we had little time, we chose for a package tour. We set off at PARQUE DAS AVES – really interesting, you can get inside the huge cages, close enough to the animals. And, with (good or bad) luck, they can land on your arms. Most pictures I took from inside the cages.
