- The Limay river is one of the best rivers in the world, and offers unique fly-fishing opportunities. It´s a tail-water fishery that flows out of Pichi Picun Leufu Dam, guaranteeing consistent flow, temperature, clarity and cleanliness of the water at all times, resulting in a large insect population. This constant food source supports a large healthy population of resident browns and rainbows. This huge river provides excellent fishing on dries, nymphs and streamers, with the possibility of catching trophy brown trout over thirty inches. We offer the opportunity to do two or three nights camping or staying at the brand new luxury Limay Lodge.
