The Caleufu, Alumine, Chimehuin and Collon Cura Rivers are still virgin with respect to the incredible fishing and the land they flow through. All of these rivers have minimal access and therefore receive little fishing pressure. It is possible to float four consecutive days and never see another human being. By floating these rivers you will also have the best chance to see wildlife such as llama, red deer, wild boar, rhea birds, and puma. The Andean Condor can also be spotted soaring high in the clouds or perched on a cliff above the river.

These float trips are an unforgettable opportunity to not only immerse yourself in the grandeur of Patagonia but also experience truly excellent fishing from sun up till sun down.

Caleufu River

The Caleufu, Alumine, Chimehuin and Collon Cura Rivers are still virgin with respect to the incredible fishing and the land they flow through. With the help of private land and restricted access, it is possible to float four consecutive days and never see another human being. By floating these rivers you will also have the best chance to see wildlife such as llama, red deer, wild boar, rhea birds, and puma. The Andean Condor can also be spotted soaring high in the clouds or perched on a cliff above the river.

Caleufu River: The headwaters of the Caleufu Rivers lie in the Lanin National Park and run for roughly 60 miles until it reaches the Alicura Reservoir. In the high elevations, the river cuts through low canyons and pine forest while in the lower portions, the river meanders through the Patagonia steppe with islands and banks lined with tall grasses and willows. The ratio of rainbows to browns is about 4:1. Browns averaging 2-4 lbs. tend to be larger then rainbows. Dry flies and nymphs all work incredibly well in this virgin river which holds several species of caddis, mayflies and small stoneflies. The river also supports a large population of pancora crabsmaking streamer fishing very effective.

	Alumine River

Alumine River: In the northern part of the province of Neuquen, the Alumine River flows out of the Alumine Lake for 100 miles until it joins with the Chimehuin River. Together these two rivers form the famous Collon Cura River. The ratio of rainbows to browns is about 1:1 with average size being about 17 inches. Trout up to 9 pounds are also caught every year. The river cuts through the dry Patagonia steppe with rocky and willow lined shores. Our longer floats of 5-6 nights are done on the Alumine.

Caleufu River

Collon Cura : The Collon Cura is actually an extension of the Alumine River and runs along route 40 south of Junin de los Andes and north of Bariloche. The river is famous for its hard fighting rainbows and browns which average 2.5 lbs. and reach up to 15 pounds. Fish hold under branches and along the banks of this slow, deep river. Streamers tend to be only slightly more effective then large dries or nymph. Wild boar, condors and deer are common sights in the early and late hours. Coming across puma dens or tracks is also common. Perhaps its finest tributary is the Quemquemtreu stream which flows though the Quemquemtreu Ranch. This river offers exceptional dry fly fishing in the early season.

	Chimehuin River

Chimehuin River: The "Chime" is one of the many famed rivers in Argentina. In fact, this is considered the first river that gave northern Patagonia its renowned trout fishing reputation. Years before Joe Brooks’s arrival, legendary Argentine angler Bebe was pulling huge trout from the river. It has produced the largest landlocked brown trout in all of Patagonia, and still today anglers gather at the boca of the Huechulafquen Lake looking to hook into one of its prized browns that migrate from the lake to the river during the fall spawning run.
From its source, the Chimehuin runs 53 kilometers through several miles of private estancias, public lands and the town of Junin de los Andes. One of the Chimehuins finest tributaries is the Quilquihue River. Both the Chimehuin and the Quilquihue are known for their great dry fishing. Nymphs and streamers are also popular to coax the large brown trout out from under submerged rocks or the willow lined bank.

Probably the finest and most effective way to fish the Chimehuin River is by floating for 2 days, 1 night and then continuing to the confluence of the Collon Cura River where we then spend 2-4 more nights on the Collon Cura River. This is one of the few places in Argentina where you can fish two rivers in one multi day float.
