Rio Quilimari is a river of the Coquimbo Region of Chile, flowing approximately 50 kilometers (31 miles) westward from its headwaters in the foothills of the Andes Mountains — at an elevation of around 1,340 meters (4,390 feet) — to its mouth at the coastal town of Quilimarí on the Pacific Ocean. The river gives its name to the Valle de Quilimarí, a valley known for its strong rural traditions and remarkable natural, archaeological, and mineral heritage. Along its course, the river feeds the Embalse Culimo, an artificial reservoir that collects waters flowing down from the valley and serves as a focal point for nature-based recreation, including sport fishing under favorable conditions. The river's mouth forms a wetland — the Humedal de la Desembocadura del Río Quilimari — a protected natural area near Pichidangui that attracts visitors for wildlife observation and relaxation. The valley sits directly inland from Pichidangui, a coastal town on the Pacific, and the entire corridor offers a blend of rural landscapes, archaeological sites including petroglyphs from the Molle, Diaguita, and Diaguita-Inca cultures, and outdoor recreation opportunities.
