Fishing in Parque Nacional Cerro Castillo

Parque Nacional Cerro Castillo sits about 57 kilometers south of Coyhaique along the Carretera Austral, in the provinces of Coyhaique and General Carrera.

The park covers 143,502 hectares of Andean Patagonian terrain shaped by glacial valleys, and the water it holds reflects that geology: clear lakes and lagoons are the dominant fishing environment, with rivers playing a secondary role.

The lake fishing is what draws most anglers to this area. The lakes around Cerro Castillo are exceptionally clear — clear enough that sight-casting to cruising trout along the shallows is a realistic approach rather than a lucky one.

Both boat fishing and wading the shallow flats and beaches are productive. Large dry flies, including beetle patterns, are the standard presentation.

Rainbow and brown trout are present, with average fish running 16 to 18 inches and larger fish a genuine possibility. River fishing exists but is limited compared to the lakes.

The Río Ibáñez, which runs near the park, sees a run of large trout moving upriver to spawn in April, making that month worth noting for anglers targeting bigger fish.

The park sits roughly two hours from Coyhaique by road, and most anglers base themselves in the village of Villa Cerro Castillo or nearby accommodations rather than day-tripping from the city.

CONAF administers the park, and visitors are required to register with park staff at the trailheads before entering.

Some access routes — including the sendero por Estero Parada and sendero por Horquetas — currently require a certified guide and prior authorization through the CONAF regional office; check current conditions before planning a backcountry fishing approach.

The standard Chilean recreational fishing license applies here. Confirm current regulations directly with CONAF or SERNAPESCA before your trip, as access conditions and any park-specific requirements can change by season.

The huemul deer is frequently spotted in this part of the Aysén region — one of the best places in Chile to see them. That's worth keeping in mind when you're wading a lakeshore at dusk and something moves in the lenga at the tree line.
