An Aerolíneas Argentinas bus leaves from the airline’s office two hours before the plane’s departure and does hotel pickups. A remise costs AR$30.
Frequent buses cross to Foz do Iguaçu, Brazil (AR$2 to AR$3/R$2 to R$3, 35 minutes), and to Ciudad del Este, Paraguay (AR$2/R$2/G5000, one hour), from the local side of the terminal. All will stop near the roundabout at the edge of town.
Groups of three or more wanting to see both sides of the falls (and the Itaipú dam) may find a taxi or remise a good idea; figure on it costing up to AR$250 for a full day of sightseeing. The tourist office may be able to arrange such trips for less. A taxi to Foz do Iguaçu costs around AR$50.
