Up to the late-1970s, there was an airport here, but it was closed, as both Santiago del Estero, 60 kilometres (37 mi) away from Termas de Río Hondo, and San Miguel de Tucumán, 90 kilometres (56 mi) away, had airports with paved runways.
The airport is beside the Río Hondo Reservoir (es), 6 kilometres (4 mi) west of the city. South approach and departure are over the water. There is a 350 metres (1,150 ft) blast pad on Runway 19. The Termas de Río Hondo VOR-DME (Ident: TRH) is located on the field.[4]
