Aviador C. Campos Airport — Chapelco/San Martin de los Andes, Argentina

Framed by the forested peaks of Argentina's Lake District, CPC serves San Martín de los Andes and neighboring Junín de los Andes in Neuquén province, a Patagonian region built almost entirely around outdoor tourism. Winter brings skiers to the slopes of Cerro Chapelco, a resort mountain visible from the terminal on clear days, while summer shifts traffic toward hikers, anglers, and road-trippers following the famous Route of the Seven Lakes through Lanín National Park's araucaria forests and volcanic scenery. CPC's official name honors aviator Carlos Campos, and mountain-ringed approaches here demand experienced flight crews familiar with the district's frequently shifting Andean winds. Seasonal charter flights supplement the regular domestic schedule connecting the airport with Buenos Aires, reflecting sharp swings in visitor numbers between ski season and the milder months.
