One of the seven wonders of nature, the Iguazu falls may be reached from two main towns, with one on either side of the falls: Puerto Iguazú in Argentina and Foz do Iguaçu in Brazil, as well as from Ciudad del Este, Paraguay, The falls are shared by the Iguazú National Park (Argentina) and Iguaçu National Park (Brazil).
On the Argentinian side
The Parque Nacional Iguazú is the main attraction
On the way to the falls, there is an animal hospital and center for rehabilitation of injured wildlife. It also carries out valuable research into the Iguazú forest environment and has a breeding program for endangered species. The tour leads you around the jungle park, there is a guide who explains how the birds and animals ended up here. It takes about 80 minutes.
Casa de Botellas
About 300m of the falls road, this fascinating place is well worth a visit. The owners have taken used packaging materials,plastic bottles, juice cartons and the like to build not only an impressive house but furnishings and a bunch of original handicrafts that make unusual gifts. The guided visit talks you through their techniques.
On the Brazilian side
The main attraction is the Parque Nacional do Iguaçu which is open every day without exception from 9:00 a.m. to 5:00 p.m.
Parque das Aves (Birds Park)
Flamingos, parrots, and toucans are some of the most colorful inhabitants of the privately run Parque das Aves.
Right outside the Parque Nacional Foz do Iguaçu, it’s an interesting complement to a visit to the falls. A winding path leads you through an untouched tropical forest and walk-through aviaries containing hundreds of species of birds. Iguanas, alligators, and other no feathered friends have their own pens.
Which side of the Iguazú Falls is better, the Argentinean or the Brazilian? This is one of the most frequently asked questions among tourists visiting the region. Usually, the reason for this question is simple curiosity, leading in many cases to an entertaining talk about the famous “rivalry” between the two neighboring countries.
In my opinion, the falls of the Brazilian side can be seen while on the Argentine side you can live them, if I seek a better view I would prefer the Brazilian side but if I seek to feel the energy of the water falling every second I would choose the Argentinean side
This one is from the Brazilian side:
