<P> Between the Cordillera Central and the Cordillera Oriental flows the Magdalena River . This 1,600 - kilometer ( 994 mi ) - long river rises near a point some 180 km ( 112 mi ) north of the border with Ecuador , where the Cordillera Oriental and the Cordillera Central diverge . Its spacious drainage area is fed by numerous mountain torrents originating high in the snowfields . The Magdalena River is generally navigable from the Caribbean Sea as far as the town of Neiva , deep in the interior , but is interrupted midway by rapids . The valley floor is very deep ; nearly 800 km ( 497 mi ) from the river 's mouth the elevation is no more than about 300 meters ( 984 ft ) . </P>
