The Andalién River is formed by the union of the Poñén from the north and the Curapalihue from the south in the commune of Florida. It then flows southwest and west, and eventually northwest into the city of Concepción, Chile. After the city of Concepción, it flows north through the former villages of Andalién and El Rosal, and then the communes of Talcahuano, and Penco. There, on its alluvial plain northeast of Concepción, it forms distributaries, and small lakes, such as the Laguna Negra, before entering the Bay of Concepción.
