One of the top rivers in Northern Patagonia, and a Patagonia Outfitters all time favorite, the Collon Cura presents very unique features. This is a large river that collects the waters from varios other tributries as it flows from North to South: Rivers Aluminé, Pulmarí, Rucachoroi, Nahuel Mapi, Quilca, Quillén, Malleo, Catan Lil, Quillquihue , Chimehuin and Quemquemtreu, shed their waters into the mighty Collon Cura River. This is a classic Patagonian plains river that meanders along the high Patagonian steppe offering ideal conditions for profuse resident wild populations of big and healthy rainbows, browns and Patagonian perch. Willow lined banks, sand cliffs and rolling hills shape the Collon Cura River’s unique and attractive landscape. Underwater life is varied and profuse.
The Collon Cura is the ‘complete sporting river’; dries, attractors, terrestrials, nymphs, streamers, tube-flies, wading, floating, matching hatches, hunting monster fish, single-handed rods, spey and switch rods, strong rainbows, monster browns. It is prolific and interesting, it is every fisherman’s river.

One of the really interesting features the Collon Cura has is the fact that it flows into a huge reservoir that is packed with huge trout and is home to a profuse ‘puyén’ minnow population. These ‘puyén’ minnows are fantastic food for trout and will migrate upriver during the fishing season attracting all kinds of big healthy trout both from the reservoir and the Collon Cura River. Minnow patterns are often deadly with big Collon Cura browns and rainbows. The other two interesting food factors featured by the Collon Cura are the green inch-worms falling from the willows along the banks (December through February) as well as its healthy ‘pancora’ crab population. All these elements are really outstanding food resources that are key to this river’s healthy fish-life, not to mention the omnipresent grass-hoppers and terrestrials and the daily mayfly, stonefly and caddis hatches. Such diversity has been sought for many anglers over the years, who won’t want to miss their yearly piscatorial pilgrimage to their magical Collon Cura.

The Collon Cura River Valley is populated with some of the most spectacular wildlife you’ll find anywhere. We utilize drift boats to cover mileage but fishing can be done both by wading and from the boat in order to reach incredibly productive hot spots, stops to wade at pools and riffles are part of the adventure. You will enjoy a wholesome picnic or an Argentine “asado” (barbecue) on the riverbank and a nice long rest before returning to more fishing well into the evening.

During the early season you can also fish the Quemquemtreu Spring Creek, a secluded and rich little stream that shines in the middle of the Patagonian Steppe.

Fishing your way down on this river reaching your next lodge without a ground transfer is one fine fly fishing experience to consider for your trip.
