Mirador del Río is a scenic viewpoint located along RP307 in the Tucumán province of Argentina. It provides an elevated perspective of the surrounding yungas forest and the river gorge below. The site serves as a popular pull-off point for travelers ascending or descending the winding mountain roads toward Tafí del Valle. It is characterized by steep topography and proximity to the Quebrada de los Sosa provincial reserve. The viewpoint is integrated into the natural landscape without significant man-made infrastructure. It offers a direct line of sight to the geological formations typical of the Sierras del Aconquija. The area is heavily influenced by the humid subtropical climate of the region, affecting local visibility and vegetation density.
