Buenaventura is a major city and port in Colombia. It is situated on Cascajal Island, where the Dagua River reaches Buenaventura Bay on the west coast of the country and has a population of around 280,000. It is Colombia's main Pacific port, handling much of the nation's coffee, as well as sugar and cotton from the fertile upper basin of the Cauca River valley, sawn wood from coastal forests of south western Colombia, and most of the gold and platinum of the Chocó region to the north. It is a major fishing port from which frozen shrimp are exported and is also the terminus of an oil pipeline from Puerto Berrío.
