When you are looking to visit the Foz do Iguaçu, you have two good options in terms of flights. The first is to fly into the Brazilian side, or the second option is to fly into the Argentinian side. The decision of which to fly into will likely be determined on where you are starting and ending your trip. If you are flying through Buenos Aires, you will likely end up landing on the Argentinian side, but if most of your itinerary is Brazilian based you can go with the Brazil airport. One factor to keep into consideration is if you are coming from the US, you will have to get a Brazilian visa to land at this airport, but if you enter Argentina you will not have to worry about this.
Overall, this is a very easy airport to navigate, as it is a very small place with just a few gates. We were treated to a band when we first arrived, and entered through just one small gate. There are two airlines that land here, TAM and GOL, both Brazilian regional airlines.
The regional airline that we chose to fly to Foz do Iguaçu was TAM Airlines. TAM is the largest of the Brazilian based airlines, and serves many cities in Brazil as well as a few other South American cities. When we flew into Foz do Iguaçu, we went through Curtiba (pronounced Curcheeba) and on the return we went direct to Rio (GIG).
Sarah and I were actually able to book this flight through American Airlines in the US, but unfortunately we will not be able to do that any more as the code share agreement ended in 2007.
In order to eat dinner outside our resort, we had to use a taxi to get into town. Our hotel had a taxi stand right outside the resort entrance and they would tell them where to take us and on the way back we had the restaurants call us a taxi. Taxis are metered here, the fare was close to R$16 each time we took one, about $8US.
There are buses every 30 minutes at peak times between Puerto Iguazu and Foz do Iguaçu. If you are only crossing for the day you don't need to get an exit and later a re-entry stamp for Argentina. Neither do you need a Brazil stamp. However, you need to state this clearly at to Argentine customs. We ended up getting the exit/entry combination for both countries which delayed us by about an hour as we had to wait for the next bus. Also, bus company tickets are not interchangeable so if you're in a hurry and the next bus is from a different company you'll need another ticket.
The journey from Puerto Iguazu to Foz do Iguaçu takes about an hour in all. From Foz do Iguaçu to the falls on the Brazilian side is another 45 minutes at least. If you only want to visit the falls then there is no need to go all the way to Foz do Iguaçu from Puerto Iguazu. Ask your driver to let you off on the main road for the falls once you´ve cleared customs. All buses accept both Pesos and Reais so you won't need to change money.
This is how you can get from the bus terminal to the falls.
At the terminal take a bus to TTU. When you get there take a bus to Parque national with the same ticket. TTU is like a small terminal where many city busses stop; You can't get in there without a ticket so that's why you don't have to buy another ticket.
The way to the falls is pretty direct and doesn't take a lot of time; The way back to the terminal takes longer. From TTU take a bus to rodoviaria (=bus terminal)
Off course you can also take a taxi but this is more expensive .
If you are looking for a private transportation option than contact Jose Chelest. I have used his services twice and can say he makes it very easy to get around. He took me to the Argentine side of the falls, Brazilian side as well as Itaipu dam tour. Rates are neg.
Enough buses to all important destinations in all the three countries meeting here. But expect sometimes long queues at the frontiers to Argetina and Paraguay - but this is no problem for the regional buses.
The city of Foz do Iguaçu has reasonably good bus services, but it is best to know a bit of Portuguese in order to use them - or at the very least it is good to have a Brazilian Portuguese travel language book with you so you can try to communicate what you need.
Some of the bus routes do not operate very frequently, and some of them are only once every half hour or so, and so it is best to know their timetable. It is possible to get it from the web site for the bus system, but you need to know a bit of Portuguese in order to get it, and also you need to know a bit about where you are going as they are listed by bus route number.
The bus services cover much of downtown, as well as most of the tourist locations that you would need to visit, including connecting the city airport to the Iguaçu National Park (Parque Nacional del Iguaçu). This bus route is number 120.
Foz do Iguaçu City Bus Services: (FozTrans) (100% Portuguese)
After the flash media stuff is overwith, you need to select "Prefeitura Municipal" from the bottom menu. A new page will open, and from the left size you will need to select "Foztrans". In the new window that opens, the left side has a section called "Transporte Coletivo" - this is the section that features information on the public bus system.
You'll probaly don't have problems to buy you ticket to go to Foz, but don't leave it for the last moment buying your return ticket.
There is many people from all around Brasil who goes to Paraguay to buy any kind of things cheaper and they come back to their cities to make bussines.
Most of the times they go in the morning and they come back at night, so the buses often are full.
I had to come back to Campinas alone because tere was no place for everybody in the buses, so you should decide when are you going to come back as soon as posible and buy the tickets.
Take a plane early in the morning and enjoy the sunrise...
Prenez l'avion le matin tres tot et profitez du lever de soleil...
There are buses leaving Foz every hour to the waterfalls, we took the bus to the main entrance and came back by taxi.
