Argentina is one of the most popular fly fishing destinations in the world due to the fast growth and sheer number of trout that inhabit the waters of its Patagonia region. In order to have any chance at catching one of Argentina’s wild brown trout, rainbow trout, or brook trout, anglers will need a fishing guide. Fishing guides in the Patagonia region are experts in their field, know exactly which fly the trout are hitting, and know where the fish are.
