The Story

Orvis-endorsed Rio Manso Lodge provides a unique Patagonian fly-fishing experience in Argentina. Unlike most of Argentina's Patagonian lodges, which are located on vast estancias surrounded by pampas, Rio Manso Lodge is surrounded by a two million-acre forested national park. The adjacent mountains and forest protect our fishing area from the famous Patagonian winds that blow across the plains to the south and east.

The temperate climate, abundance of food, and scarcity of fishing pressure have produced outstanding fishing in the Rio Manso's waters. It is common to catch fish in the two- to four-pound range daily, and there is a reasonable chance you will catch a five- to 10-pound trout during a week of fishing. The lodge itself is very comfortable, with outstanding views from each of our nine rooms. Guests enjoy international-style meals enhanced by local dishes and superb Argentine wines. Relax around the massive stone fireplace after a full day's fishing, or loosen up with a massage. Non-anglers have a wide variety of activities to choose from and families are welcome. Read our Patagonia fly-fishing lodge reviews to learn more about Rio Manso Lodge.

Located just 90 minutes south of Bariloche airport, Rio Manso Lodge sits on the shore of Lake Hess alongside the Rio Manso in the Andes Lake District of Northern Patagonia. Surrounded by an ecologically preserved rain forest, Rio Manso Lodge accommodates up to 12 flyfishers in comfortable, cozy rooms with private bathrooms, Jacuzzi tubs. Full-size beds ensure you'll sleep in comfort. All rooms have a spectacular view of Mount Tronador and its glaciers, Lake Hess, and the Manso River. A welcoming fire will greet you after a full day of fishing and the warm living room is the perfect place to sip a cocktail and plan your strategy for tomorrow's fishing. A wading room is conveniently located just inside the entrance and the comfortable dining room and bar will help you relax and enjoy every moment of your stay. Telephone and Internet access are available, as well as a small fly shop that serves as a good backup for those items you mysteriously forgot to bring. Rental gear is also available.

Food & Drink

Meals are served in the main dining room and are a satisfying conclusion to a day on the water or exploring the wonders of Patagonia. Our professionally-trained chef creates delightful cuisine that reflects an international flavor, always made with the freshest ingredients.

Gone are the days when traveling to Argentina meant eating meat at every meal. You’re as likely to have pasta, fish, or chicken as beef at our table. Vegetarian meals are also available for our guests. We serve a wide variety of dishes that reflect both the cultural diversity of the area and the worldly influence of today’s culinary landscape. All our meals are served with complimentary Argentine wines. Should you have any special dietary needs, we are more than happy to develop a special menu for you.

We have not forgotten our roots and the local custom of the Argentine asado. One of the highlights of the week, this traditional Argentine grill features such items as beef, lamb and pork. An asado also includes bread, a simple mixed salad of, for instance, lettuce, tomato and onions, or it could be accompanied with verdurajo (grilled vegetables), a mixture made of potatoes, corn, onion and eggplant cooked on the parrilla and seasoned with olive oil and salt. No matter what you try, it’s all part of the adventure at Rio Manso Lodge.

Gear Recommendations:

Fly rods: You should bring at least two fly rods: 5-7 wts for streamer fishing and windier conditions and perhaps a 4 wt for evening or small-stream dry-fly fishing. We strongly recommend bringing a third 5 wt as a backup. There are a limited number of rods at the lodge, in the event you break one.

Fly reels: Reels should be high quality, preferably disc-drag models loaded with a minimum of 80/100 yards of backing. The occasional 8-10 lb fish will test your gear to the limit! You may want a backup reel or extra spools for your reel. Having two rods rigged, one with floating line and one with sinking line will maximize your fishing time.

Lines: Floating and sinking lines cover the fishing at Rio Manso Lodge. Weight-forward or double-taper floating lines are fine for dry-fly and small streamer fishing. We recommend that you bring a 30 ft 200-250 gram fast-sink line for your reel. The fast-sinking lines are especially effective in the lakes and the faster, deeper stretches of the river. Most of our lakes have abrupt drop offs along the edges and the sinking lines get the fly down to where the fish are. If you have not cast a fast sinking line before, we recommend you get a little practice in before you come. It's not difficult to learn, but it will increase your fishing success and pleasure if you already have this technique down.

Leaders: 7_ to 9 ft 2X-5X leaders will suffice for most fishing. We like to use fluorocarbon for tippets for its added abrasion resistance and low light reflectivity. Bring some extra spools of tippet in the 2X -6X range. Evening fishing in the channels near the lodge can become very technical at times.

Flies: Much of our fishing during the day is with streamers or large attractor pattern dry flies. We can provide you with a fly list for complete recommendations. We do carry a full assortment of productive patterns at the lodge.

Waders: Breathable waders are the best way to maximize your fishing experience. You can layer poly-pro or fleece underneath in cold conditions and turn them down during hot weather.

Wading shoes: Sturdy shoes with good felt or rubber soles. While the footing is good, the Manso has many stretches of fast water with strong currents. Please be sure your waders and wading shoes are clean and dry before visiting to prevent the spread of invasive species like whirling disease, zebra mussels, or didymo. We recommend the new rubber-soled wading shoes and waders.

The climate in our part of Patagonia is very similar to the northern United States. You can expect temperatures to range from the mid 40s early in the season, to the 80s during the summer months of January through March.

Clothing: Layering is the mantra when fishing. Today's high-tech garments offer almost limitless options for staying warm and dry. Fly-fishing specific clothing is best, but light cotton sweaters, short and long sleeve shirts and trousers, long underwear, wool sweaters, windbreaker, wool socks, etc. will work as well. Big temperature changes can occur in a matter of hours in the mountains, so make sure you are prepared. Contact us if you have any questions.

Critical Items: A breathable (GORE-TEX' or similar) rain jacket, hat, polarized glasses, sunscreen.

What to Bring:

  • Small day pack or tackle bag
  • Fishing hat
  • Polarized sunglasses
  • Digital camera
  • Sun screen and lip balm
  • Insect repellent, BuzzOff' clothing is very effective
  • Binoculars


The Rio Manso fishing season runs from November through April and is easily divided into three sections:

The early season is often marked by high water, which gradually recedes in December. We'll start the season fishing mostly weighted streamers, often on sinking lines. Mayfly and caddis hatches begin by the end of November and intensify in December providing increasingly better dry fly fishing. Early to middle December will see dragonflies hatching on the lakes and rivers bringing up the biggest fish and providing exciting dry-fly action. Dragonfly nymphs and wooly buggers are effective at this time and dry-fly fishing often lasts all day.

Excellent evening dry fly action continues through January. The river channels near the lodge feature multiple mayfly and caddis hatches that bring fish up, especially early and late in the day. As temps warm in February, day time fishing can slow down on both the river and in the lakes. Terrestrials play an increasingly important role in the daily diet as summer progresses.

As fall approaches, water temperatures begin to cool with the first southern cold front and the fish again become more active. Evening fishing is characterized by a brief flurry of activity right before dark with caddis patterns, while most daytime fishing is with streamers or nymphs. April is when the big browns and brook trout migrate into smaller tributaries.

Rio Manso Lodge sits in a secluded portion of Nahuel Huapi National Park in Argentina's Northern Patagonia region. The largest and oldest national park in Argentina, the park encompasses nearly two million acres. The Rio Manso starts high on the eastern flanks of Mount Tronador, the park's tallest mountain at 11,453 feet. Tronador means 'thunder', and on some days during the summer, avalanches high on the mountain can be heard by guests at the lodge, a dozen miles away. Surrounded by old growth forest, the lodge itself is located just 2,500 feet above sea level which eliminates any worries of altitude sickness. Like many rivers in Patagonia, the Rio Manso flows undammed on its journey to the sea. Unlike many of the rivers in this area, the Rio Manso actually flows into the Pacific Ocean rather than the Atlantic. The river, small streams, and lakes near the lodge offer a variety of fishing conditions from spring creeks to roaring fast water to calm deep pools. The nearby forests are ideal for horseback riding, birding, rafting, hiking and exploring. Some guests have even skied the glaciers on Tronador!

Typical Weather:

Like many alpine locations, weather can be variable during the fishing season. Early season tends to be cooler and wetter with daytime temps running from 50-80 degrees. November mornings can be just above freezing, although they often warm quickly. Summer air temperatures average around 70-75 degrees F. February is the warmest and driest month with temperatures that may reach the mid to upper 80s during the day. Early and late season have a higher chance of rain and often see daytime temperatures in the mid-50s. The climate is very similar to Montana's Rocky Mountains, upper Michigan, or northern New England.

Which airport do I fly into?

Most guests fly into San Carlos de Bariloche (BRC) from Buenos Aires where we pick them up at the airport. Aerolineas Argentinas and LATAM both have direct flights from BA.

What is a typical fishing day like?

If you've fished with a guide, outfitter or lodge in North America, our daily schedule will feel quite familiar. Unlike most lodges, however, we are usually out on the water for 9-10 hours. If you really like to fish, you'll love the length of our fishing day. For those who consider fishing just one part of a great Patagonia experience, we're happy to bring you in whenever you're ready.

While there is no such thing as an ordinary day at Rio Manso Lodge, we do have sort of a routine that begins most days with breakfast at 8am. After hot coffee, eggs, cereal, fresh fruit, or whatever else you need to get going, you'll meet your guide in the wader room around 9am. With the exception of a trip to the Limay, Lower Manso, or a horse ride into Lago Los Cesares for big brookies and bigger browns, none of our waters are more than 20-25 minutes from the lodge which allows you to spend more time fishing and less time riding around. When an early departure is the case, you will have breakfast at 7:30 A.M.

We fish until around midday, then stop for a streamside lunch which might include such items as steaks, quiches, sandwiches, salads, cheese, and fresh bread. Some of our guests like to take a siesta after lunch, but we're not surprised if you want to get right back on the water!

After fishing, through the afternoon, you would normally get off the water by 7 P.M. or so, and return to the lodge to clean up, take a sauna, or perhaps get a massage. We serve drinks and hors d'oeuvres before dinner in front of the fireplace. Dinner is usually served between 9:00 and 10:00, although we've been known to eat much later if the fish are rising and you just can't tear yourself away.

We are very flexible when it comes to arranging your day. If you have a special request, just let us know and we will do our best to accommodate you to give you the best experience possible.

What are the best arrival and departure times?

Our fishing week normally begins with guests arriving on Sunday. However, we have no set booking days and will work with you to develop your visit for any day of the week.

Is there a minimum stay requirement?

There is no minimum stay requirement. Visit us for a day or two or stay for a week or more. However, since a trip to Argentina and Patagonia takes some time to get here, we usually recommend you come for at least a week.

Can I mix fishing and non-fishing days?

Yes, you can mix fishing and non-fishing days together during your week, if you desire.

Can we rent tackle?

Rio Manso Lodge has tackle available for rent on a daily basis that includes rod and reel, waders, and wading shoes. We also have some terminal tackle such as leaders and flies available for purchase at the lodge.

Additional Activities:

There are a multitude of guided hikes available from the lodge that range from simple excursions into the woods or walks to the nearby waterfall, to more strenuous expeditions climbing the surrounding mountain peaks of the Andes. Dayhikers near the lodge will be able to explore the temperate Patagonian forest and perhaps glimpse local fauna such as fox, pudu (deer), or even the elusive puma.

Our birding walks and expeditions are usually led by Dr. Lorenzo Sympson, a noted authority on Andean condors, and founding member and head of the ornithological committee of SNAP (Sociedad Naturalista Andino Patagonica), a regional NGO dedicated to the conservation of Patagonia's unique ecosystems. He participated in the re-introduction of captive bred condors in Patagonia, and is the coordinator of a program designed for researching their biology and behavior. Dozens of species are found in the area including the Magellanic woodpecker, Austral parakeets, the endangered torrent duck, and the Andean condor.

We offer several ways to explore the waters of the surrounding park. Our Motorized Boat Tour of the lakes or a River Float Trip will both take you into areas that are unreachable on foot, and give you the opportunity to see more of the beautiful Patagonia forest and ecosystem. You can combine them with a Birding Trip for even more enjoyment. There are miles of Class I-III rapids to float near the lodge, as well as wilder waters further down river.

Riding at Rio Manso Lodge provides a rare glimpse into the surrounding pristine forest. Much of this forest is old growth with ancient alerce trees, some of the oldest on earth.

We have opened several riding trails thru the lush evergreen forest that lead to secluded places such as lagoons, cascades, lakes and rivers. Most of our programs are easy to medium difficulty. All of our trips are guided by an experienced English-speaking horseman who is adept at helping you spot wildlife.

Our horses are young, sturdy animals that have been raised in the back country, used to moving around our dense forests and very tame, ideal for inexperienced riders, but still fun when cantering comes into mind!
