I am currently staying about 20 minutes north of a town called San Martin de Los Andes, which is located in the lake region of Argentine Patagonia. San Martin, as locals refer to it, is a fly fishing hub nestled alongside Lácar Lake, surrounded by the Andes and not far from Argentina's border with Chile. Hiking and backpacking options are plentiful with Argentina's version of the Appalachian trail, the Huella Andina, spreading out in either direction north and south.
