Cataratas Del Iguazú International Airport (IGR/SARI) serves Puerto Iguazú in the northeastern Argentine province of Misiones, near the famous Iguazu Falls and the borders with Brazil and Paraguay. It is the primary air access point for one of the world's most visited natural wonders, a UNESCO World Heritage Site. The airport handles both domestic routes connecting to Buenos Aires and other Argentine cities, as well as international flights, primarily to and from Brazil. Passenger traffic is strongly driven by tourism to Iguazu Falls National Park, making it one of Argentina's busiest leisure-oriented airports. The facility has undergone modernization efforts to increase capacity in line with growing tourism demand in the region. Its proximity to the tri-border area gives it a unique geographic and logistical significance in South America.
