Campo di volo Porto Pino is a small general aviation airfield located near Sant'Anna Arresi in the Sulcis-Iglesiente area of southwestern Sardinia, Italy. It carries the ICAO designator SU01 and has no assigned IATA code, reflecting its status as a minor, non-commercial facility. The airfield primarily serves light aircraft, ultralight flying, and recreational aviation activities in the region. It is situated close to the Porto Pino nature reserve, a coastal area known for its sand dunes and lagoons. Commercial airline operations are not conducted here, and passengers seeking scheduled services would need to use nearby Cagliari Elmas Airport.
