Nestled in the Andean foothills of Chile's O'Higgins Region, the Río Claro is a gem of a trout stream flowing through dramatic mountain scenery near San Fernando. This freestone river winds through a valley characterized by classic Andean terrain, offering anglers a combination of productive trout habitat and breathtaking wilderness. The river features ample runs, cuts, and eddies that define prime trout water, making it a rewarding destination for both experienced fly fishers and newcomers to the sport. A small tributary of the Río Claro also flows through the grounds of Tunaman Lodge, giving visiting anglers the rare opportunity to cast for rainbow trout just steps from their accommodations.
