One of my favorite beverages while I was in Foz was the local drink Guarana. Although there are multiple different brands of this beverage, the consensus of my research pointed to Antarctica as the preferred brand. Similar to the Coke vs. Pepsi controversy, sometimes in Brazil you are not able to get exactly what you want, because certain restaurants only carry one or the other, it seemed fairly consistent in Foz to have the Antarctica brand available.
Guarana is actually a plant, which has small coffee bean sized berries which can be used to create the beverage, although there is not much actual juice in the flavored soft drink.
The Border Crossing
To get back and forth between Puerto Iguazu and Foz do Iguacu you do not have to travel far. The photo shows one of our crossings over the Rio Iguazu on the modern Tancredo Neves International Bridge.
As far as the tours were concerned, once the bus driver picked us up from our hotel, they wanted passports and then wrote various details of all the passengers on a sheet of paper. On arrival at the Brazil border post near the bridge, the driver would head off into the building with his piece of paper and the passports. A short time later, he would return with our documents and away we went, never having actually shown our faces to the Brazilian authorities.
Check for Visa requirements though. Brazil has a tit-for-tat policy of requiring them if your country requires them to get one. In my case, due to a little spat between Canada and Brazil over aircraft manufacturing subsidies, before leaving on our trip I had to get my first visa (US$80) since going to Egypt in 1974.
Iguazu waterfalls II
It´s possible to visit the waterfalls from both sides (the brazilian and the argentinian). Maybe the argentinan size is more impressive, but from the brazilian size you have a more panoramic angle. I recommend to visit both.
If you want to visit the waterfalls you have to paid an entrance fee (it´s possible to pay it in cruzeiros, argentinian pesos, dollars and with credit card). There are some restaurants and souvenirs shops in the entrance building.
The Bird Park is located on the righthand-side of the road just before you get to the National Park waterfall entrance. It features over 1000 birds of 150 different species including many Brazilian birds such as macaws, parrots and toucans with their huge colourful bills who are very tame along with flamingos, ostriches, rheas and cranes. You follow a trail that takes you through some nice woody areas where they also have some reptiles and butterflies. There is a walk-through aviary where the birds come up very close. In fact one flew down and landed on my back! Scared the living bejesus out of me I can tell you! Tickets are a little expensive but it's well worth a visit.
Open: daily from 8:30am-6pm.
