The Collon Cura presents matchless features and structures, during its length this large river receives waters from various other tributries such as Aluminé, Chimehuin, Malleo, Caleufu, Pulmarí, Quillén, Quillquihue and Quemquemtreu.

This patagonian steppe river, home of resident wild rainbows, browns and patagonian perch, presents willowed lined banks, sand cliffs and hills which forge an attractive landscape.

One interesting feature on this river structure is the fact that it flows into a huge reservoir that is packed with huge trout and is home to an abundant ‘puyén’ minnow population. These minnows are highly productive 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.

Other two fascinating food factors featured by the Collon Cura are the green inch-worms falling from the willows along the banks which takes place between December and February as well as its healthy ‘pancora’ crab population. All these elements are essential to this river healthy fish-life, not to mention the residence grass-hoppers, terrestrials and the daily mayfly, stonefly and caddis hatches. Such diversity has been appreciated for many anglers over the years, who wouldn’t want to miss their yearly fishing crusade to the enchanting Collon Cura.
