The Río Blanco (Spanish for "white river") is a river of Chile. It originates close to Cerro Altar and flows generally northward for 15km (09miles) until it joins the Juncal River, at an elevation of approximately 1430m (4,690feet),[1] forming the Aconcagua River. The mouth of the river is located close to Chile Route 60.
Los Leones River is the main tributary of the river.[1] The inferior course of the Río Blanco is adjacent to Río Blanco National Reserve.
