Across all of these destinations, it\u2019s possible to achieve the classic \u201cPatagonian Grand Slam\u201d \u2014 landing brown, rainbow, and brook trout all in the same day. And in midsummer, the entire basin comes alive with the famous Dragonfly Hatch, one of the most exciting times of year for dry-fly fishing, when big trout attack large foamy terrestrials like Fat Alberts, Chernobyl Ants, or realistic dragonfly imitations.<\/p>\n\n\n\n
Our destinations within the basin<\/p>\n\n\n\n
Lower Manso River \u2014 Begins at Lake Steffen and winds for about seven miles until it meets the Villegas River, near the Chilean border, forming the southern boundary of the National Park. This is a float-fishing stretch of exceptional beauty, with waters in striking shades of green and blue running through pristine Andean forest. It offers excellent fishing, including right at its mouth on Lake Steffen.<\/p>\n\n\n\n
Middle Manso River \u2014 Begins on the southwestern shore of Lake Mascardi and flows into Lake Moscos, whose outflow is renowned for outstanding dry-fly fishing in summer. It then continues to La Medialuna Lagoon, a small, reed-fringed spot with a magical sense of seclusion, before completing the float to the exit point through pools, runs, riffles, and picture-perfect bends.<\/p>\n\n\n\n
Lakes Fonck and Roca \u2014 Two medium-sized glacial lakes with limited access, which helps preserve the quality of the fishery. Rainbow and brook trout predominate, with good-sized brown trout occasionally showing up. Lake Fonck is divided into Fonck Chico (surrounded by dense reeds, fishable only by boat) and Fonck Grande (with varied structure and inflow from the Calote and Fr\u00edo streams). Lake Roca, bordered by coihue forest, is fed by three streams \u2014 Expedicionarios, Linco, and Felipe \u2014 creating highly productive structure. Depending on the season and conditions, we prioritize one or the other to make the most of the day.<\/p>\n\n\n\n
Hess Lake & Channels \u2014 A small but highly productive lake, with reed-lined shores creating ideal habitat for dry-fly fishing. It offers spectacular views of Mount Tronador, with its permanent glaciers, along with a network of channels combining stunning scenery with excellent dry-fly and nymph fishing.<\/p>\n\n\n\n
