Pedro Villarroel C. Airport is a small regional aerodrome located near Combarbala, a town in the Coquimbo Region of northern-central Chile. It serves primarily general aviation and occasional charter or light aircraft operations, supporting the local agricultural and mining communities. The airport bears the name of Pedro Villarroel, reflecting local heritage. Given its limited infrastructure and the relatively small population of Combarbala, it does not support scheduled commercial airline services and operates on a modest scale typical of rural Chilean aerodromes.
