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 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.
At the moment the borders are closed, people can´t cross borders to see the Iguazu Falls in Argentina. We will let people know when it is open.
For backpackers that have plenty of time, here is a (link with the bus timetable is not working) 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.
