upper limay river — dina huapi
The river that rises in Lake Nahuel Huapi, next to Bariloche. Blue water, strong current and large trout; fly fishing with release in the upper section.
The Limay rises in Lake Nahuel Huapi, at Dina Huapi, and flows east between Neuquén and Río Negro. The upper section runs inside Nahuel Huapi National Park, with very clear water, a stony bed and a strong current. Brown and rainbow trout live in the river and, in autumn, large fish come up from the lake. Fishing is with flies, wading or from a rowboat, using nymphs, streamers and dry flies during hatches. Downstream, the Middle Limay, below the Piedra del Águila dam, is another stretch famous for large trout.

what you can catch here
before you fish in Argentina
There is no national license: the sport fishing license belongs to each province. In northern Patagonia, the Patagonian Regulation permit issued by Neuquén, Río Negro, Chubut or the National Parks Administration (APN) is valid in all these jurisdictions, including the southern parks; in 2025/2026 it cost $40,000 per season for residents of the country and from $50,000 (day) to $280,000 (season) for non-resident foreigners, with online purchase. Santa Cruz and Tierra del Fuego have their own permits (TDF 2026/2027: foreigners from $78,000 per day to $260,000 per season). On the coast (Buenos Aires, Entre Ríos, Corrientes) each province issues its own.
- The license is provincial. In Patagonian national parks, the APN permit or the provinces' Patagonian permit is valid, and fishing is only allowed in the environments listed in the parks' annex.
- Patagonian Regulation (2025/2026): general season from November 1 to May 1; in rivers and streams, including 200 m from their mouths, mandatory release with a single barbless hook, except for exceptions in the annexes; as a rule, one artificial lure with a single hook; selling fish prohibited; felt-soled boots prohibited.
- In national parks, all native species (perch, Patagonian pejerrey, catfish, peladillas) must be released; Atlantic salmon must be released in all environments under the regulation.
- Golden dorado: in Corrientes it is a Provincial Natural Monument (Law 6,730/2025); in Entre Ríos commercial fishing is prohibited and sport fishing is catch-and-release only (Law 11,174/2024); on the Uruguay River, shared with Uruguay, there's a CARU closed season from September 1 to December 31.
