The altitude of the rest of the territory varies between the 2,100 and the 2,600 metres, and the topography is characterised by a number of small hills, some of which may rise to a greater height and slope like Cerro del Capiro, located in limits with the municipality of La Ceja. A sharper mountainous system emerges towards the West of the municipality, which becomes a physical barrier between the Valley of the Aburrá and the Plateau of Rionegro, from where the main affluents of the Negro River are born. The main hills of the mountainous chain that surround the Valley by Rionegro are: Alto Gordo, Alto de Amariles, Alto de Salazar o La Pilastra, Cerro Verde, Alto de Careperro, Alto de Pantanillo, Cerro Corcovado and Cerro del Capiro.
