San Gerónimo Airport (Spanish: Aeródromo de San Gerónimo, (ICAO: SCSG)) is an airstrip serving Algarrobo, a Pacific coastal city in the Valparaíso Region of Chile.

The airstrip is 4.6 kilometres (2.9 mi) inland from the coast.

The runway parallels an east–west road atop a low ridge.

Another road intersects the runway at a shallow angle, giving the runway the visual appearance of being bent.

The Santo Domingo VOR-DME (Ident: SNO) is located 18.8 nautical miles (34.8 km) south of San Gerónimo Airport[4]
