Arroyo Tastil is a stream located in the high-altitude, arid region of Salta, Argentina, near the archaeological site of Santa Rosa de Tastil. The area is accessed via Ruta Nacional 51, approximately 100 kilometers north of the city of Salta, and sits at an elevation of 3,200 meters above sea level. This high-altitude environment creates a dry climate with significant temperature variations. The stream's course runs along or near Route 51, and paddlers can enter the waterway directly through its streambed. The surrounding landscape is part of a significant pre-Inca archaeological zone, offering a culturally rich backdrop for a paddling trip. The terrain also attracts other outdoor enthusiasts, with rock climbing being practiced in areas near the stream. While specific paddling routes are not detailed, the presence of a feature named "Cascadita del Arroyo Tastil" suggests the watercourse includes small waterfalls or cascades, indicating variable flow and potential technical sections. No specific regulations prohibiting paddling are mentioned, but the shared use of the area for climbing and its cultural significance implies paddlers should be mindful of other visitors and any protected archaeological zones.
