Río Blanco is a stream flowing through the Los Lagos Region of Chile, situated at approximately 41°13′S, 72°37′W in one of Patagonia's most celebrated fishing landscapes. This area of southern Chile is renowned for its pristine cold-water fisheries, dramatic volcanic scenery, and the exceptional quality of its trout waters. The Los Lagos Region surrounds Río Blanco with a rich network of rivers, lakes, and streams, placing it within easy reach of some of Chile's most productive angling destinations. The stream's setting among old-growth forests and Andean foothills is characteristic of the region's wild, undeveloped character, offering anglers an intimate and scenic fishing experience in a part of the world where wild trout thrive in remarkably clear, cold water.
