Course[change | change source]
The Maipo river starts on the Andes, in the place called Los Nacimientos, on the side of the Maipo volcano, in the San José de Maipo commune (Santiago Metropolitan Region), at an elevation of about 3,135 m (10,285 ft).
From its start, the river flows to the northwest through the Cajón del Maipo, a canyon; the El Volcán and Yeso rivers join the Maio before San José de Maipo near the town of San Gabriel and as right tributaries. After the city of San José de Maipo the river is joined, also as a right tributary, by the Colorado river and then turns to the southwest.
After a total of about 110 km (68 mi), Maipo river leaves the Andes to the south of Puente Alto, still at near 800 m (2,625 ft) of altitude above sea level, and gets into the Maipo valley. Near Talagante, after flowing through the city of Santiago, the Mapocho river joins, as a right tributary, the Maipo river.
