Río Chico is a stream located in Tierra del Fuego, Argentina, flowing through the northeastern side of the island alongside several other notable trout rivers. It is part of a remarkable network of Patagonian waterways that draw fly anglers from around the world seeking wild, remote fishing experiences in one of the most dramatic landscapes on earth. The river runs through open Fuegian steppe and offers the kind of uncrowded, exploratory fishing that has become increasingly rare elsewhere in the world.
