Arroyo Huaraco is a stream located within the Neuquén River basin in the province of Neuquén, Argentine Patagonia — one of South America's most celebrated sport fishing destinations. Nestled in the rugged, wild landscapes of the Alto Neuquén region, this water body sits within a network of rivers, streams, and lagoons that define the northern and central zones of the province. The surrounding environment is characterized by the raw, untamed scenery typical of Patagonian backcountry, offering anglers a genuine sense of solitude and immersion in nature. The crystal-clear waters of the region are emblematic of Neuquén's fishing reputation, and Arroyo Huaraco contributes to the broader Neuquén River watershed that encompasses some of Argentina's finest sport fishing waters.
