I am flying into IGR in Argentina in the morning, and hoping to spend the day viewing the falls on the Argentina side and then traveling across the border to stay in Foz in Brazil. We're hoping to spend the next morning exploring the Brazilian side of the falls and then fly out of IGU.
Can anyone advise on the best way to do this? Is there a car rental place that lets you rent a car at IGR in Argentina and return it at IGU in Brazil? Are there any difficulties when crossing the border in a rented vehicle?
If we can't rent a car, is there a way to explore the falls on the Argentina side and brazilian side with our luggage?
Any advise would be greatly appreciated.
