Cordillera Central
Antioquia is the sixth-largest Department of Colombia. It is predominantly mountainous, crossed by the Cordillera Central and the Cordillera Occidental of the Andes. The Cordillera Central divides to form the Aburrá valley, in which the capital, Medellín, is located. The Cordillera Central forms the plateaus of Santa Rosa de Osos and Rionegro.
