Rio Manso's surrounding waters are some of the best in Patagonia for outstanding dry fly fishing during the epic dragon fly hatch. Every December, when several days of warm weather trigger the emergence of this tasty meal, big browns, strong rainbows, and beautiful brook trout feed on top. With average size fish of 20 inches(50cm), Rio Manso offers a tremendous fishing experience and the chance to spend almost all of your fishing with dry flies. The surrounding lakes and kilometers of river fishing make for a diverse fishing trip for any angler.
