Aeropuerto Nacional de Salto del Guairá is a small domestic airport serving the city of Salto del Guairá in the Canindeyú Department of eastern Paraguay, situated near the tri-border area where Paraguay, Brazil, and a portion of the region converge along the Paraná River. The airport operates under the oversight of Dirección Nacional de Aeronáutica Civil (DINAC), Paraguay's civil aviation authority, and primarily handles light aircraft, charter flights, and occasional scheduled regional services rather than large commercial operations. Salto del Guairá itself is an important commercial hub on the Paraguayan-Brazilian border, and the airport serves as a supplementary transport option for travelers and cargo in a region more commonly accessed by road from Asunción or Brazilian border cities.
