The Río Rehue is a significant fishing destination in Chile's Araucania Region, flowing through a landscape characterized by its clear, cold waters and diverse aquatic habitats. This river system offers anglers a classic Patagonian fishing experience, with its waters supporting healthy populations of both rainbow and brown trout. The river's varied structure, from fast-moving riffles to deep, slow-moving pools, provides excellent habitat for trout throughout its course. Access is primarily facilitated by Ruta R-260, which runs alongside sections of the river, offering several well-defined public access points for wade fishing and bank access.
