Lago Chepelmut is a beautiful lake nestled in the Isla Grande region of Tierra del Fuego, Argentina — one of the world's most storied destinations for trout fishing at the southern tip of the continent. Surrounded by the raw, windswept landscapes characteristic of Patagonian Tierra del Fuego, this lake sits within a network of interconnected waters that includes Lago Yehuin and various tributary streams and rivers. The region's remote character, pristine cold-water habitat, and healthy trout populations make Lago Chepelmut a compelling destination for fly anglers and spin fishers alike who are willing to make the journey to the end of the world.
