collón curá river
Large steppe river, born where the Aluminé meets the Chimehuín. Drift boat fishing for large trout.
The Collón Curá is born from the meeting of the Aluminé and Chimehuín rivers, near Junín de los Andes, and runs across the steppe to the Limay. It is a wide, powerful river, with banks, islands and long runs. The classic approach is drift boat fishing with a guide, casting streamers and big flies toward the banks. Rainbow and large brown trout share the river with the native perca criolla. There are day trips and multi-day floats with camping.

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.
- Tierra del Fuego (2026/2027): season from October 30, 2026 to May 2, 2027, fly and spinning only, and mandatory release in all provincial environments starting March 1, 2027.
