Santo Antônio Airport is a small general aviation facility located near Cáceres, a municipality in the western part of Mato Grosso state, Brazil. It operates under the ICAO code SS7K and does not hold an IATA code, reflecting its limited role in commercial air traffic. The airport primarily serves private aircraft, agricultural aviation, and light regional operations common to Brazil's interior. Cáceres itself is situated near the Pantanal wetlands, and the airport supports activities related to agribusiness, ecotourism, and local connectivity in this remote region.
