So, you like trout that live a good part of their lives getting fat in the ocean, eh? Brown trout that regularly exceed 20 pounds? Well, the Rio Grande River, in southern Terra del Fuego, Argentina, is the place for you. It’s known as the most prolific sea-run brown trout fishery in the world. That said, it’s super windy and caters mostly to the two-handed-casting crowd, so make sure to brush up on your spey skills before you head down.
