Quebrada El Arrayan is a short watercourse, approximately 3 kilometers in length, located in the Coquimbo Region of northern Chile. The water body flows through the area near Vicuña, specifically passing through the locality of Los Cox. The broader hydrological basin of Quebrada del Arrayán is recognized for its intense hydrological activity, which can include significant seasonal water flow and potential for flooding, indicating variable conditions that paddlers must consider. This characteristic suggests the stream's flow is likely seasonal and subject to substantial change, making it critical to assess conditions before any trip. Specific paddling and fishing access points are noted to exist, though their precise locations are not detailed. The area is of interest for birdwatching, as evidenced by its designation as an eBird hotspot, implying that paddlers may observe diverse avian wildlife along its course. The overall character of the paddling experience is shaped by its setting in a northern Chilean watershed, where water levels and safety hazards are directly influenced by the intense hydrological patterns of the region.
