A wonder of nature.
Iguazu waterfalls are one of those things you need to see in your lifetime. Pictures you'll see, stories you'll read will never express this grandeur in front of your eyes. Iguazu is the most scenically phenomenal of all the world's waterfalls.
Three quarters of Iguazu falls belong to Argentina and one to Brazil. None of them to be missed. Argentina has a more intimate look, you can walk amongst the falls, whereas Brazil has better vista views. To visit both of them you need two days, or one full and one half day would be enough.
Fly in.
Air transportation was more convenient for us in Brazilian side, so we flew there and stayed there as accommodation was cheaper there as well.
Getting there.
First day in the morning we took a trip to Argentina, it might sound complicated to cross the border by public bus, but it was very easy and very cheap. Bus goes frequently (every half an hour) from bus stop. If you wait in one of the stops in Av. das Cataratas there is only two busses, one to airport and one to Argentina they both clearly marked. Take the one to Argentina, it costs only 4 reals. When the bus reaches the border, you need to disembark and stamp your passport at the customs, same bus will wait, just don't forget how it looked like. When you’re entering the bus - notify the driver that you are going to the waterfalls so he knows that he needs to stop at a specific bus stop. Bus drops you at the station just before entering city in Argentina, you need to walk to another side of the road and wait for another bus going to Cataratas de Iguazu.
If you meet other people at the station you can share a taxi together it would be the same price. Usually drivers wait for tourists at the spot, so negotiate with them. On your way back you can do the same or take a public bus, and disembark at the same station you disembarked from Brazil bus, across the street to the same station you took taxi or bus to waterfalls and wait for a public bus to Brazil, it will be clearly marked. Last bus from Argentina leaves at 7 pm so don't be late!
Early birds get the worms.
It's a little bit of hustle, but it's so worth it, as the Argentinian side has so much to offer. Don't forget your bug spray, raincoat and something to protect your camera. We would also recommend to take your own snacks as food outlets didn't look nice and were very crowded. If you come early enough there is nowhere to rush, you can walk slowly on the catwalks and enjoy every view, there is plenty of time to do all trails. We started with Garganta del Diablo, and would urge anyone to do the same if you come early to skip the crowd.
Brasilian side.
Second day you will see your walking paths from Brazilian side and you will be amazed! This side opens up panoramic views of waterfalls from a distance, and its hard to to believe that just yesterday you were walking between them.
Easy access.
Brazilian side takes only half day, and it's easy on your legs, you don't need to walk much. Public transportation to Foz do Iguaçu is simple, you just take city bus to the airport, and disembark at the last station.
An experience of a lifetime.
Although both sides were unbelievably beautiful, we enjoyed walking between waterfalls on the Argentinian side more. We never felt so small and so powerless against Mother Nature before. A truly humbling experience we will never forget.
