About this Water
- Freestone
- Best months: Dec–March (austral summer)
The Rio Gallegos in Santa Cruz Province, Argentina is the second great sea-run brown trout river of Tierra del Fuego and Patagonia — a wide, powerful steppe river receiving fresh chrome fish from the South Atlantic from December through April. Las Buitreras Lodge operates with a strictly limited number of rods on this remarkable fishery, ensuring quality and maintaining the health of the run. Fish averaging 10-18 lbs with trophy specimens to 25+ lbs make this one of the finest sea-run brown trout fisheries in the world.
The Rio Gallegos sea-run browns travel thousands of miles from feeding grounds in the South Atlantic before entering the river — these ocean-conditioned fish are in peak physical shape and fight with extraordinary power in the cold, swift Patagonian current.

The Río Gallegos in Santa Cruz province is one of Patagonia's premier sea-run brown trout (sea trout) rivers. Chrome-bright fish running to 15+ lbs provide exceptional fishing against a windswept Patagonian backdrop. The river's tidal influence and strong winds require adaptable fishing techniques.

- Woolly Bugger Olive #4–8

Technique
Swing large flies through the tidal sections and lower river pools. Strong Patagonian winds often require casting directly into the wind. Guides are essential for maximizing time on productive water.
Seasonal Notes
Sea-run brown trout enter from the South Atlantic in December–January to spawn. Fish are in their best condition shortly after entering fresh water. Not the primary approach on this Patagonian sea-trout fishery.
