This is the most important river in the National Park, big water flowing out of the huge Nahuel Huapi from its eastern end about 17 km (11mi) from the city, winding through dry, rocky mesas spotted with pine forests and offering wonderful scenery and great weather. It is one of our strongest recommendations for fly-fishing, with countless opportunities for all skill levels, populated with mostly rainbow and brown trout, and some Patagonian perch. From November through March the dry fly possibilities abound, and during the last month of the season, in April, the amazing big trout migrate to the river from the lake. Near Bariloche there are five different sections on the river to choose from, each about 10 miles long. In the course of five days we can potentially go to a different section of the river every day and float about 10 miles each day without repeating fishing areas. Fishing Life’s options include half- or full-day trips, floating and wading. You can lodge in town, or we can camp overnight on the river (typically for two or three nights) spending our days drifting along 50 km (32 mi). The extremely clear water, beautiful scenery, and great fishing make this floating trip something truly unforgettable.
