Quebrada Matancilla is a waterway located in the Antofagasta Region of Chile. It is situated in a cold desert climate at coordinates approximately 25° 1' 13" S, 70° 22' 48" W. The water body is classified as a creek or quebrada, and one source indicates it has a length of approximately 17 kilometers. The surrounding landscape is historically significant, as the creek was once a route for gathering and bartering caravans. A walking exploration of the area follows the creek and ends at a geological feature known as the Rainbow Valley. The area is promoted for fishing, with resources available to uncover fishing access points, boat ramps, and facilities for a day trip. The region's arid, desert environment suggests the creek's flow is likely intermittent or seasonal, heavily dependent on rare rainfall events in the Andes, which would dictate the feasibility and safety of paddling. No specific regulations, hazards, water quality details, or recommended paddling routes are provided.
