The topography of Oro Valley is distinguished by the Cañada del Oro riverbed bisecting the town. The eastern banks of the Cañada del Oro rise dramatically to the Santa Catalina Mountains. The western banks of the Cañada del Oro rise more gradually to a plateau and the foothills of the Tortolita Mountains farther north.
