Argentinian Side

The Iguazu National Park (Argentinian side) does give you a taste of the most powerful component of Iguazu Falls - the Devil's Throat (La Garganta del Diablo). From the Paseo Inferior (Lower Level) catwalks, you'll only be limited to a rather distant view of the Devil's Throat. However, once you get onto the Paseo Garganta del Diablo (The Devil's Throat Walk), you'll get right up to the brink of the mighty torrent of water for a top-down view. An experience you definitely do not want to miss. The Argentina side encompasses a much larger portion of Iguazu Falls than the Brazil side (at least from an area standpoint). This includes all of the San Martin Island (a large parcel of land that comprises one of the series of islands splitting the falls into two main components - Devil's Throat and then the rest). Catwalks are far longer in length than its Brazilian counterpart and this means you get right up to the majority of the network of waterfalls that make up the greater Iguazu Falls.

Brazilian Side

Visiting the Iguassu National Park (Brazilian side) allows travelers to take the most stunning panoramic pictures of the falls. Ideal for passengers with mobility difficulties, the paths are designed with multiple ramps (opposed to the multiple steps found on the Argentinian side). Among the park facilities there is an elevator for easier access between the upper and lower levels (another big difference with the Argentinian park), and a close by gift shop and restaurant, ideal for a refreshing stop. It is possible to tour through the Brazilian side of the Falls in a short 4-hour visit if you are not planning to go biking, hiking or on a river adventure. Keep in mind, however, that a Visa is required for U.S. citizens who wish to go to Brazil and must be requested to the Brazilian Consulate in the USA way in advance before the trip. In general lines, the Argentinian and Brazilian sides complement each other, and you will need to go to the Argentinian side if you want to have the adrenaline filled experience of getting so close to the falls at the Devil's Throat.
