Río Loro (also referred to locally as Río del Loro) is a stream flowing through the Tafí Viejo area of Tucumán Province in northwestern Argentina, situated at approximately 26°37′S, 65°11′W. This small but productive waterway winds through the diverse landscapes characteristic of the Tucumán region, offering anglers an accessible and rewarding fishing experience in a setting that blends subtropical foothills with the rugged terrain of the Sierras Chicas. The river draws both local and visiting anglers, particularly those targeting the native trahira, which is the species most closely associated with this stream.
