Make your own way to Jorge Newbery Airfield in Buenos Aires for your 1.5-hour flight to Puerto Iguazu, which sits just across the Iguazu River from Brazil and is only 11 miles (18 km) from Iguassu Falls. When you arrive, you’ll be picked up by your guide and driven to your chosen hotel. The rest of the day is yours to have dinner in town (own expense) and do what you wish, while start knowing this nice city.
