The river is navigable for only half of its length, 200 kilometres (120 mi) starting in Montería, the largest city in its basin.
The river flows between the eastern and middle prongs of the Cordillera Occidental.
There has been extensive habitat destruction in the region, causing problems to many species in the area.
Two parrots that are endemic to the river valley, the Sinú brown-throated parakeet[3] (Aratinga pertinax griseipecta) and the Sinú parakeet (Pyrrhura picta subandina), have not been recorded for decades and are feared extinct.
