Arroyo de la Quebrada Tumbaya Grande is a stream located in the province of Jujuy, in northwestern Argentina. Stretching approximately 8 miles, this waterway winds through the dramatic high-altitude landscape characteristic of the Jujuy region, where rugged quebrada terrain shapes both the character of the stream and the experience of fishing it. The surrounding geography — defined by steep canyon walls, arid slopes, and the geological complexity of the Andean foothills — gives this arroyo a distinct personality that sets it apart from lowland fisheries. Access to the stream and any fishing activity are governed by Argentine national regulations, with stream access rights derived from the Código Civil y Comercial at the national level rather than provincial statute.
