The Fishing

The northern Patagonia region around the towns of Junín and San Martin de los Andes has the largest variety of trout streams in Argentina. You can fish 15 rivers and 20 lakes within a two-hour radius of San Martin de los Andes. And although the area conta


Our custom-tailored fishing packages will allow you to fish the very best waters in ways that match your preferences perfectly. From long days fishing to evenings enjoying splendid dinners and relaxation at the lodge, you’ll experience the very best of Patagonia with us. When we talk about Patagonia Norte it is very important to know about the different options you can have to fly fish, so knowing the rivers and their fishing options is critical, from which ones are good for wadeing and which one will be good for floating. There are rivers that are very technical and for dry flies and with higher difficulties for casting, like Malleo and Quillen; to floating rivers like Alumine and Collon Cura. Or a unique calm clear water stream  like Filo Huaum.



The Malleo River (Rio Malleo) is one of the most famous rivers in Patagonia because of its dry fly fishing. This midsize freestone river forms out of Tromen Lake at the base of the Lanín Volcano and flows for 32 miles before joining the Aluminé River. Its meandering course takes it through steep canyons, large meadows and big stands of willows. The Malleo has the best and most predictable hatches throughout the season.

A main road follows this river for most of its length, allowing easy to moderate access. It is not large enough to float, so you will be wade fishing here. While you might encounter a few fishermen on Malleo, it is never crowded.

This river can be divided into two sections, upper and lower. The upper section is characterized by fast flows and large boulders, and it is heavily lined with willows. The lower section flows through the Mapuche Indian Reservation. Here the river slows and becomes a bit more canyon like, featuring large rock outcroppings with willows lining only one bank at a time, making it easier to wade and move around.



Housing the largest trout population in the region, the Chimehuin River is the icon of fly fishing in northern Patagonia. It is a classic large, free-flowing trout stream. You could spend the entire season here and still not have enough time to discover all of its pools, runs and willow-lined banks.

This river starts in Lake Huechulafquen at the base of the Lanín Volcano and runs for about 30 miles until it joins the Collon Cura River.

The Chimehuin flows through the town of Junín, and you’ll find the best fishing between the town and where the river joins the Aluminé to form the Collon Cura. In this lower section, the Chimehuin slows and creates spectacular dry fly fishing, especially during caterpillar season. You can wade or float in this large, gentle-flowing segment of the river.

Although the Chimehuin is very popular, most of the lower section is secluded and accessible only through our negotiations with private ranches. You’ll have these waters largely to yourself with little fishing pressure.



Home to very large trout, The Collon Cura is the largest river system in the region. It is formed by the confluence of the Aluminé, the Chimehuin and Catan-Lil Rivers, and then flows nearly 50 miles until reaching the Piedra del Águila Reservoir.

The Collon Cura is a great dry fly river early in the season, makes a major change to a unique minnow fishery from mid to late summer, and then transitions back to a great dry fly fishery during the fall.

By late January, massive numbers of minnows migrate from the lake upstream to spawn. Once the migration starts, the trout stop feeding on insects and concentrate solely on eating the minnows they find trapped in the riffles. The swarm of migrating minnows is so heavy that the riffles, eddies and shallows turn black.

We float nearly 20 miles on the Collon Cura over three days, camping on islands and fishing parts of the river where you will see no other anglers.



This river is one of the longest rivers in northern Patagonia. Most of its 80 miles is great water for trout fishing and can be floated. It presents countless fishing opportunities.

The Aluminé is a freestone river that forms out of Aluminé Lake and flows until it joins the Catan-Lil and Chimehuin to become the Collon Cura River. Access to many sections of this stream is limited or very difficult, so you won’t find many people around. Fishing pressure is very low.

In addition to daily floats, we take island camping float trips so you can experience the best of what of this great stream offers.

In January and February, the annual inchworm hatch creates spectacular fishing on the Aluminé. Even the large, wily brown trout will get downright stupid during this time of year, allowing you to sight fish for them.



This is probably one of the most beautiful streams in northern Patagonia. Starting from the junction of the Meliquina and Filo Hua-Hum Rivers, the Caleufu River begins as a mountain stream running though a unique Rocky canyon with spectacular rock formations. It becomes a medium-size river and flows for about 60 miles to the Collon Cura River and the Alicurá Reservoir.

Most of our trips on the Caleufu are done by floating. Although the water level drops dramatically each season, this river can be floated until mid to late January. Our multi-day float will take you through spectacular scenery and steep rock formations as Andean Condors soar overhead.

After the water drops too low to float on the Caleufu, we concentrate our fishing on the lower portion of the river, where a minnow migration similar to that of the Collon Cura River takes place.



The Quillen River is a tributary of the upper Aluminé is a great stream for dry fly fishing. It forms from Quillen Lake in the Lanín National Park.

This freestone river flows for about 16 miles until its junction with the Aluminé River. While the upper section of the river runs slowly and winds through a beautiful valley, the gradient on the lower section becomes steeper and presents the angler with classic pocket water.

The Quillen is too small to float and is fished by only a handful of wade fishermen per year.

Gear and Equipment

While there are some fly shops in the area we will be staying, getting to the shops during

their hours of operation can be difficult.  Also you may find the need for supplies while you are on a float and camp trip so be prepared. The guides will also have flies but you may find yourself up the river or in a different location than your guide at points in the trip so it is nice to have some of your own stuff.   There is no way to predict every fishing situation that you may encounter  but,  after  years  of  traveling  in  Argentina  to  here  is  the  list  of  tackle  that  we recommend.


For San Martin area and Surrounding Streams


    At least two rods per angler in the event that one gets broken.

    Do not bring a rod smaller than a 4 wt and bring at least one very good 5wt.

    8’6” to 9’6” rods are ideal.

A good 6   or 7wt is very nice if the wind blows, which it often does and if you are planning on fish streamers


    Two good reels with working drags; they should balance your rods.

    Spare spools for your reels


    Weight forward floating lines in good condition and in line weights to match your rods.

    If you plan on streamer fishing bring one sink tip 175 grains to 200 grains


    Three 9’ 3x

    Three 9’ 4x


    One spool each 2x, 3x, 4x, 5x, fluorocarbon is highly recommended.

Recommended Clothing

Since we will be fishing in a mountainous area, expect weather changes daily.   You should plan on dressing in layers and on the worst possible weather you can think up. You will see temperature ranges from 35-90 often in the same day. Do not leave home without a good fleece jacket and a good gore-tex raincoat.  Remember that fleece will keep you warm even when wet.  Do not plan on wearing denim around the water, because once it is wet then it stays wet.

Traveling Here

Most international flights leave the US in the evening and land in Buenos Aires (EZE) the following morning. Delta (stop in Atlanta), United (non-stop, the fastest flight of 10 hours), American (connection in Miami) offer daily flights. Also check LAN flights but make sure that the connection is in Miami and not in Santiago de Chile because it takes longer.

There, you will be met by a company representative who will drive you to the lodge.

NOTE: Make sure that you have plenty of time (at least 4 hours) in between flights once you reach Buenos Aires. You will have to clear customs and take a trip by taxi or private car to the domestic airport. This trip usually takes 50 minutes but depending on traffic, it can take more than one hour. *
