NORTHERN PATAGONIA, FROM NEUQUÉN TO COYHAIQUE

ARGENTINA AND CHILE

Northern Patagonia crosses the Andes, joining Argentina’s celebrated trout country with the remote rivers and lakes of southern Chile. Its extraordinary variety allows anglers to combine broad freestone rivers, clear spring creeks, glacial lakes, technical walk-and-wade water and long float-fishing days within one carefully planned journey.

In Argentina, the program extends from Neuquén’s volcanic highlands and the rivers around San Martín de los Andes, through Río Negro’s lake country, to the forests, valleys and clear waters of Chubut. Tres Rios Casa de Campo provides private-group access to the Chimehuín, Aluminé and Collón Curá, while Challhuaquen Lodge and La Pilarica Lodge open the rivers, lakes and spring creeks surrounding Trevelin, Cholila and Los Alerces National Park, with Brook Trout Base Camp offering access to Río Pico and Rio Corcovado.

West of the Andes, Coyhaique is the gateway to Chile’s Aysén region. Cisnes River Lodge offers an intimate base beside the Río Cisnes, with access to the Río Mañihuales, neighbouring lakes and contrasting sections of remote Chilean water.

Each lodge works as a destination in its own right. They can also be combined into a longer Northern Patagonia itinerary, with Isolation Outfitters coordinating the fishing, accommodation, transfers and connections between regions.

CHALLHUAQUEN LODGE · MARCH 6 TO 13, 2027

Each hosted week can be booked separately. The February La Pilarica and March Challhuaquen weeks also run consecutively and can be combined into an extended Northern Patagonia

NEUQUÉN PROVINCE

San Martín de los Andes and Junín de los Andes provide access to Neuquén’s best-known trout waters. The Aluminé, Chimehuín and Collón Curá offer long float days through broad valleys, while the Malleo, Caleufú and smaller tributaries reward precise dry-fly and walk-and-wade fishing.

Filo Hua Hum, Traful and the Limay expand the range from intimate lake-fed water to powerful currents holding migratory trout. Neuquén suits anglers who value variety and the freedom to match each day’s river and technique to the conditions.

RÍO NEGRO PROVINCE

Bariloche anchors Río Negro’s lake district, where Nahuel Huapi, the Upper Limay and the Manso systems combine glacial scenery with productive trout water. Fishing can move between lake-fed channels, freestone runs and secluded backcountry reaches.

The region pairs wilderness with comfortable accommodation, excellent food and straightforward access, making it equally suitable as a dedicated destination or a natural connection between northern and southern Patagonia.

THE WATERS OF NORTHERN PATAGONIA

FIVE DISTINCT FISHING REGIONS

CHUBUT PROVINCE

Esquel and Trevelin open the forests, lakes and river systems surrounding Los Alerces National Park. The Arrayanes, Rivadavia and Carrileufú provide clear, beautifully structured float water, while the Corintos and smaller spring-creek-style fisheries offer more technical wading.

Beyond the forests, the Río Chubut, Tecka and Percy systems cross open Patagonian steppe. This contrast between glacial water, pastoral valleys and remote freestones gives Chubut exceptional depth within a relatively compact fishing region.

CORCOVADO, RÍO PICO AND THE SOUTH

Farther south, the Río Corcovado and Río Pico districts lead into quieter country shaped by freestone rivers, secluded lakes and privately accessed estancia water. Brown, rainbow and brook trout allow guides to build varied programs around conditions and seasonal activity.

Brook Trout Base Camp provides a natural base for exploring this southern network. Set on a quiet bend of the Río Corcovado, its off-grid cabins place anglers close to the Engaño and Lago Vintter watersheds, as well as the spring creeks, small lakes and freestone rivers surrounding Río Pico. Trophy brook trout are the principal attraction, with resident and migratory rainbows and browns adding further variety to a genuinely remote fishing program.

CHILEAN PATAGONIA: COYHAIQUE AND AYSÉN

Across the Andes, Coyhaique provides the practical gateway to Chile’s Aysén Region. The Río Cisnes, Río Mañihuales, selected tributaries and nearby lakes offer a distinctly different rhythm of fishing amid native forest, mountain valleys and lightly travelled country.

Float fishing covers long sections of the principal rivers, while upper reaches and tributaries create opportunities to wade. Lakes provide another option when weather or river levels favour still water. Guides adjust the location and technique each day rather than following a fixed itinerary.

Aysén can anchor a dedicated Chilean lodge week or add a contrasting chapter to an Argentine itinerary, combining remote water and low fishing pressure with practical air access through Balmaceda and Santiago.

ONE REGION OR A LONGER JOURNEY

Each region works independently, but they can also be connected into a longer Northern Patagonia itinerary. Isolation Outfitters can coordinate the lodges, fishing, transfers and border or flight connections required to make the journey work as one coherent program.
