The Río Hualinchay is a river located in the Tucumán province of Argentina, near the town of San Pedro de Colalao. The river flows through the paraje (small settlement) of Hualinchay, which sits at an elevation of approximately 1,700 meters above sea level. This area is characterized by a mountainous landscape, offering a natural and scenic environment for visitors. A primary access point for the river is the Hualinchay Campground, which serves as a starting location for routes along the watercourse. From this campground, one paddling or hiking route follows the river to the confluence where the Río Hualinchay meets the Río Tacana. The region is noted for its natural and cultural richness, providing a remote and picturesque setting. The presence of a dedicated campground suggests basic facilities for visitors. The area's appeal lies in its secluded mountain character, making it a destination for outdoor activities like kayaking, as indicated by its listing on paddling and fishing planning platforms.
