Fishing in Neuquén

Neuquén sits in the northwestern corner of Argentine Patagonia, where the Andes form the Chilean border and the landscape drops east through forests, volcanic plateaus, and eventually dry steppe.

The water here comes from Andean snowmelt and glacier-fed lakes — cold, clear, and moving fast through river valleys that have been drawing fly fishers from around the world for decades.

Trout are the main event: rainbow, brown, and brook, all wild, all holding in water that ranges from broad freestone rivers to quiet lake margins.

The season runs roughly from mid-November through mid-April, and most anglers aim for the middle of that window when summer flows settle and fish are actively feeding on the surface.

The southern end of the province is where the famous names cluster — the Río Chimehuín, the Río Malleo, and the Río Limay are rivers that have built reputations over generations of serious fishing.

Lago Huechulafquen and Lago Nahuel Huapi anchor the lake fishing in that region, with long shorelines and deep water that hold big browns into the later part of the season. North of the classic circuits, the fishing changes character.

Rivers like the Trocomán and Nahueve run through drier, more open country — cattle ranch territory where access depends on relationships with estancia families rather than boat ramps and put-ins. Fewer anglers reach this water, and the fish show it.

Lago Traful, Lago Correntoso, and Lago Lácar each have their own personality.

Correntoso is known for the short, powerful river connecting it to Nahuel Huapi — a stretch that concentrates fish in ways that make it one of the more talked-about spots in the province.

Traful is quieter, surrounded by cypress forest, with clear water that rewards careful presentation. Lago Lolog, near San Martín de los Andes, is another lake worth knowing, particularly for anglers who want to mix lake and river fishing in the same area.

A fishing licence is required throughout Neuquén — it covers lakes and rivers across Neuquén, Río Negro, and Chubut, and is available through sports shops and municipal offices in the region.

Many waters operate under catch-and-release rules, and fly-fishing-only restrictions apply on a number of the better-known rivers.

Check current regulations with the provincial authority before you go, since rules on specific stretches can change between seasons. What stays consistent is the ethic.

Catch-and-release is the norm here, not the exception, and the quality of the fishing in Neuquén's best waters depends on it staying that way.
