The great lake of Tierra del Fuego, shared with Chile, surrounded by Fuegian forest, with brown trout, brook trout and perch. A huge sheet of water in an imposing southern setting.
You fish from shore, with fly and trolling, mainly in summer. The mouths of the rivers that feed it concentrate the activity. Access is along Route 3 from Tolhuin or Ushuaia, which makes it one of the easiest great Patagonian lakes to visit.

Dark: each species' peak months. Medium: its season at this place. “Abundant here” marks the most common ones in Lake Fagnano.
For a species of 0.5 to 2 kg that lives in cold streams and lagoons, the ideal gear is light and sensitive, allowing you to enjoy the fight and present small lures and flies with precision.
Spinning:
Fly:
Round it out with barbless hooks if you are going to practice catch-and-release, a hook-removal tool (forceps), a soft-mesh (rubber) net so as not to harm the fish, and waders if you are going to wade into the cold water.
Light spinning with small spoons, micro-jigs and soft plastics, or fly with small streamers. Bait: worm. It keeps company with the trout in Patagonian lakes and rivers.

Gear is chosen according to the environment and the expected size. A versatile, concrete setup:
Spinning (general use, rivers and lakes):
Fly fishing:
Recommended accessories: rubber net (less harm to the fish for release), forceps for removing hooks, barbless hooks, and waders for safe wading in cold water.
The gear is matched to the setting and the size of trout you are after, but these setups cover most situations in Argentina:
Spinning (general use, trout of 1 to 3 kg):
Fly:
For trophy specimens (5-10+ kg at the Strobel): step up the power—medium/medium-heavy spinning with 15-20 lb braid and a robust fluoro leader, or a 7/8 fly outfit—because these are fish with strength and runs far superior to the average trout.
In every case: a well-adjusted drag, sharp hooks (barbless if you are going to release), and a rubber net to handle the fish with the least possible harm.
