Quebrada Rio Seco is a watercourse in Chile's arid Arica y Parinacota Region. The water body is part of a larger hydrological system that includes the Rio Seco basin, along with the Quebrada Chusmiza and Rio Tignamar. A primary access point for paddlers is found at Puente Teresa, a bridge which provides a location for putting in or taking out. Another significant access area is located near Ruta 5 Norte, the main north-south highway, offering convenient entry for those traveling by road. The region's climate is extremely dry, which suggests the water flow in this quebrada is likely intermittent or seasonal, dependent on rare rainfall events in the highlands. The surrounding landscape is characterized by the stark beauty of the Atacama Desert, one of the driest places on Earth, presenting a unique and challenging environment for any paddling activity. Facilities specifically for paddlers appear limited, though the Puente Teresa area is noted to have amenities that could support a day trip, including boat ramp access. The area is also recognized by anglers, indicating potential shared use of the waterway. Paddlers should be prepared for significant logistical planning due to the remote desert location and should verify water levels and flow conditions well in advance of any trip, as the name "Rio Seco" (Dry River) implies periods of very low or no water.
