If you are staying on the Brazilian side of Iguassu (see previous post for where to stay), it is a a quick one hour drive over to the Argentina side. You will need to bring your passports and stop and get some pecos (there is a gift shop about 10 mins before the boarder where you can exchange your money). As you drive over the bridge before you get to the customs entrance you will be in 3 countries at once: Brazil, Argentina and Paraguay (pretty cool right). FYI if you are an American you will need to pay a fee to enter into Argentina, this payment allows you to go in and out of Argentina as much as you want for 10 years. The Argentina side encompasses a larger area of the park so get ready to hike and explore as you will probably need about 5-6 hours on this side.
Once you enter the park there are 3 trails, so you can start wherever you want, I recommend starting with the middle trail, then the Paseo Ingerior (lower level catwalks) then the La Garganta del Diablo known as the Devil’s Throat. Check out some of the pics from the middle and lower trails:
The Argentina side is really spectacular and an active fun day! There are a few restaurants and ‘fast food’ options, I will tell you that Restaurant La Selva, was very disappointing. It was a way too expensive buffet for what it was, cost us the same as if we had gone to a nice restaurant in Sao Paulo. Once you have finished exploring the park and are ready to head back to the Brazil side, make sure you stop at some of the specialty wine stores, we got 4 really nice bottles of wine for only $56!
