Iguassu Falls Brazil and Argentina are in front of each other but if one is in at the falls in Brazil and want to see the falls in Argentina needs to drive 44 km (28 miles) and cross two borders to get there. Looks simple as one sees on the map, but it can be difficult if there are lines at the borders during busy times. It is mandatory to stamp passports or passenger list while crossing borders.

For backpackers that have plenty of time, here is a (link for backpackers) around Iguassu Falls.

For people that don´t have much time, it is possible to visit both sides of the falls in a day. If one got plenty of time available is recommended to split in two days visit.

To enter Paraguay and travel further one needs to stamp the passport at the border and show the yellow fever card (no need any more to fill in the healthy declaration)

​For people that visit ONLY Ciudad del Este city, they don't require anything. People usually go to Paraguay for shopping because of the duty-free market. There is also a big street market. 
There is a small waterfall called Monday falls near Puerto Franco town. One can also visit the Itaipu Dam from the Paraguayan side, we suggest one to do it on the Brazil side on the panoramic buses. 

​For people traveling in Argentina, it is better to cash dollars on the blue dollar rate. Bring the new blue dollar crisp bills. They give a poor rate for 50, 20, 10 and 5 bills. The bills must be in excellent condition. They do not accept old bills. 

Sometimes it is convenient to pay for bills using a credit card. 
Some foreign credit cards companies have been using the blue dollar rate in Argentina.
Some people prefer to cash using (Wester Union).

There is only one word to say about the Brazilian side of Iguassu Falls, PANORAMIC. Yes, the best panoramic view one will only have from Brazil. Some of the waterfalls can be seen only walking from the Brazilian side. 

Walking around the Brazil side of the Iguazu Falls
Walking around the trails on the Brazilian side is much easier than walking on the Argentine side of the waterfalls. There is only one trail, one mile long with lots of stairs on the way.  In the beginning, from the first lookout, one will be impressed by the amazing panoramic view of the waterfalls in Argentina.  Sometimes there are animals on the trail like the coati (Nasua nasua) begging for food. They are nice animals, but our food is not good for them to eat. Is forbidden to feed animals in the park. As one walk, the trails get better and better with different views until one arrives at the bridge. That is the best part, the feeling of the water on the face. Taking marvelous pictures of rainbows circling the waterfalls. After the trail one will approach the foot of some waterfalls for some other spectacular photos.  There are two ways to reach the top, by stairs or by lift. One can decide about it according to the size of the line for the lift. As one arrives at the top, there is the grand finale, with some panoramic pictures. From the top one walk to the square, from where the buses are departing. At the square, there are choices for food and a cold beer. From the same place buses are departing to the entrance of the National Park. 

On the way back there are some optional tours like the boat ride at the falls, the Bird Park and also the helicopter ride over the falls and also the National Park. 

(they spell Iguassu with double S and  C in Brazil), in Argentina with Z)

Yes, one can walk at the falls in Brazil wearing flip-flops or training shoes.
