Сан-Луис Кильота
The color that identifies the club is red (present in their uniform since the formation as Union La Calera) and disputes their home games at the Estadio Municipal Nicolás Chahuán Nazar. Nevertheless, due to its reconstruction, around 2017 and 2018 they moved to Estadio Municipal Lucio Fariña Fernández in neighboring Quillota (which has a capacity for 7703 spectators). Their main local rivals are San Luis de Quillota.
