Río Blanco (Aconcagua)

The Río Blanco (Spanish for "white river") is a river of Chile. It originates close to Cerro Altar and flows generally northward for 15 km (9.3 mi) until it joins the Juncal River, at an altitude of approximately 1,430 m (4,690 ft), 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. The inferior course of the Río Blanco is adjacent to Río Blanco National Reserve.
