A BATTLE AT THE WORLD'S END
Marina Dombaj (née Gibson) hunts giant sea-trout in the culturally rich wilderness of southern Argentina
WHETHER YOU are an avid dry-fly trout-fisher, Spey-casting fanatic, or a seasoned predator angler, there are few places on Earth that cater to all interests.
But, with world-renowned sea-trout rivers in the wilds of Tierra del Fuego to its south and golden dorado in the blistering heat further north, Argentina has it all. Here, you can fish for migratory freshwater fish and jungle species in the same season and, bizarrely, at the same time of year.
My most recent trips were with my husband, Stephan, in 2022 and 2026, and were packed with searches for different species in rivers across the country. The first trip was just the two of us; on our most recent adventure, we were a family of three. Our daughter was born in March 2025 and has just completed a four-week fishing bender, travelling roughly 22,000 miles over 12 flights in search of king salmon, brown trout, golden dorado, and sea-trout.
In this article, I’m going to delve into the world-renowned sea-trout fishing on the Rio Grande and Rio Menendez in Tierra del Fuego and reveal some traditions that you simply can’t ignore when in Argentina.
From its Andean source to the Atlantic Ocean, the Rio Grande is home to half a dozen sea-trout lodges, each controlling their own beats and maintaining conservation practices to protect this unique fishery.

Despite its far-flung reputation, reaching the Rio Grande is straightforward. International flights connect through Buenos Aires, followed by a short domestic flight to Tierra del Fuego, where lodge transfers complete the journey into this epic landscape.
Tierra del Fuego, which means “Land of Fire”, is named after the fires and smoke signals made by the indigenous Yaghan and Selk'nam people along its coastline. When Portuguese explorer Ferdinand Magellan first saw these fires in 1520, his European mind assumed they signalled conflict. In reality, the fires were used to help the native people survive the region’s cold, harsh climate.

Standing there at times, it can feel as if you have landed on the moon
Known as “el fin del mundo” (the end of the world), Tierra del Fuego sits at the southern edge of South America, just before Antarctica. Its vast, windswept terrain is littered only with the bones of guanaco — small, llama-like animals — and, with not a tree in sight, its wide skies are filled with awe-inspiring sunrises and sunsets. Standing there at times, it can feel as if you have landed on the moon.
I’ve fished both Villa Maria and Kau Tapen, and while they have much in common, each offers a distinct experience. Villa Maria sits closer to the estuary, meaning the river is wider and holds the freshest fish off the tide. It’s a six-rod lodge with about ten miles of fishing, three guides and a fantastic, intimate setup right in the middle of a working sheep estancia, or ranch.
Kau Tapen is 15 fishing miles from Villa Maria. Here, the river is small to medium in size and has roughly 40 miles of fishing. This was the first lodge opened by the fly-fishing travel company Nervous Waters, and takes its name from the indigenous Selk’nam language, often translated as “place of fish”. Kau Tapen also includes the Rio Menendez, a very small river that is perfect for fishing with a single-handed rod.
Making memories
One of the most astonishing things about the rivers in the south of Argentina is that trout aren’t native to them. In fact, if it weren’t for John Goodall, a British expatriate who stocked the Rio Grande in 1935, we wouldn’t now be witnessing some of the biggest sea-run brown trout in the world.
Fishing on the Rio Grande is like little else on Earth, largely due to the extraordinary density of its sea-trout and, of course, their legendary size. There is always the chance of landing a double-figure fish and, if you are lucky, a specimen weighing over 20 pounds.

On the last morning of my recent trip, we were fishing on the Rio Menendez. My fly had hardly touched the water when Ned, who was on a fishing work experience placement, came tearing up to our pool and shouted that John (one of the guests) had just caught a 21lb sea-trout, and asked if it would be OK for me to come and take a photo.

We frantically reeled in, jumped in the car, and rushed over to where they’d landed this beast. It was a beautiful female, not fully coloured up yet, but with a slight warm tone, her cheeks glinting turquoise green and her scales a soft, warm grey.
The most impressive part of the whole story was that John had caught her on a split-cane bamboo rod.
John was kind enough that, after he and his guide, Christian, had released the fish, he said that I could have a go with the rod. After a few casts down the pool, I landed a small sea-trout. The rod was a joy to use, and I really got into the groove after slowing my casting stroke down.
We then headed back to our pool, and within a few minutes I hooked a big fish just off a long green patch of bank. As usual, my line immediately wrapped itself around the reel, so I ran straight after the fish, trying to keep the pressure off as I freed the coils. I eventually managed to start playing him again — the fish was angry, giving huge head shakes and pulling me around like a train.
South American gray foxes were introduced to these parts in the 1950’s to control the European rabbit population.
The best part of the whole fight was the drama unfolding on the far bank: a fox came tearing upstream, and right behind it was a herd of guanacos with their heads down, aggressively chasing it. Luckily, the fox got away, but my fish didn’t — not yet, at least. After a few more minutes, we beached him, took a couple of photos, and released him.
We had more action before heading back to the lodge for lunch, including a fish landed on a rubber-leg nymph. Another one thrashed at a foam dry-fly — a first for me with sea-trout. It was one of the most exciting mornings of fishing I’ve had.

Each day is unique
The tactics on the Rio Grande are particularly exciting for those that, like me, love the technical side of casting. I enjoy methodically working my way down a pool and trying to get my fly as close to the far bank as possible. I also like how you can experiment with different retrieves: the roly-poly, long and slow strips, jigging the fly, or making short and fast strips. It all makes the fishing so exciting and active, and there’s never a moment when your mind drifts off and you start thinking about the pressures of real life.
The guides know this water intimately and will keep you on your toes, regularly changing flies and tactics
The setting is also strikingly remote. Aside from your guide, your only companions are condors circling overhead, guanacos roaming the banks, and wild gray foxes occasionally wandering by. On one occasion, an encounter with local wildlife was a little too close for comfort. While night-fishing for sea-trout, one of our friends managed to hook a beaver! He was sure he’d connected with a real monster.
The guides know this water intimately and will keep you on your toes, regularly changing flies and tactics. One great thing is that you spend a day with each guide, and each brings a different level of knowledge and energy. Their depth of experience is huge — some have a few seasons, others have over 20, and many have guided at Kau Tapen as well as other lodges, giving them real insight into the river and its sea-trout.
What really stood out was that even the long-serving guides were still full of enthusiasm. They keep you excited right through to the last cast. By the end of the week, you will have picked up a wealth of new tips and tricks. Every day on the river feels special.
Immerse yourself
Visiting Argentina for fishing is a magnificent experience, but it would be a great shame to miss out on the country’s wonderful traditions. From tango in the streets of La Boca to the street food of Buenos Aires, I’d advise you to travel, drink, eat, and enjoy your way through every corner of what the country has to offer. Then, you can return home not only with tales of the big fish you caught, but also with experiences of a unique and deeply rooted culture.
You can’t go to Argentina without trying the legendary asado. I’m afraid barbecues just won’t cut it once this has been experienced. The term “asado” comes from the Spanish word asar, meaning “to roast”. It’s a traditional South American technique for slowly cooking a variety of meat cuts over an open fire, notably a whole lamb that is crucified on an iron cross and perched vertically over a fire pit. The local cuisine goes well beyond steak and includes offal, blood sausages, and matambre — a very thin cut of pork flank.

Naturally, you need wine to digest the quantity of meat consumed during an asado — it isn't a true asado without it. Argentine wines will be flowing freely, and, alongside the meat, there will be a few simple yet delicious sides to balance the meal.
If you have a sweet tooth, I’d like to introduce you to alfajores. These are a bit like a Wagon Wheel: two biscuits with a filling, usually coated in chocolate. Traditionally, that filling is dulce de leche — a thick, creamy, caramel-like sauce — while the outside comes in all manner of disguises including dark, milk or white chocolate, or even a simple sugar-meringue coating.
At the airport in Buenos Aires, I tried a newcomer on the block: the Dubai chocolate, which, to be honest, was wildly overrated. But then I found it — the Havanna brand’s Mar del Plata, featuring a double dose of creamy whipped dulce de leche with sea salt. It’s the best one I’ve tasted, and I’ve tasted a lot!
And if you really want to take your cultural immersion to the next level, dress the part. Pull on some bombachas, the loose, pleated riding trousers traditionally worn by gauchos; alpargatas, the lightweight canvas slip-on shoes with rope soles that are perfect for everyday wear; and a boina, the classic soft wool beret that completes the look. You might get a few funny looks walking the streets back home, but you’ll fit right in during your trip.
A lesson in asado
Chef Lukas Escobar from Kau Tapen Lodge talks to Marina about why asado holds such a special place for both locals and visitors alike.
What’s that, mate?
The moment you set foot in Argentina, you will see lots of funny-looking cups in all sorts of sizes, made from materials including metal, wood, horn and ceramic, each accompanied by a metal straw known as the bombilla. The contents of the cup resemble chaff — small horse-feed shavings that I used to feed my childhood pony. Of course, it’s not chaff; it’s yerba mate, a traditional South American drink made from the dried, crushed leaves of the Ilex paraguariensis holly tree. It has an earthy, sometimes smoky flavour and a caffeine kick similar to coffee or tea.
Most Argentines have a longstanding relationship with mate. There are cultural and social connections, as well as etiquette, that surround it, and the drink is integral to the daily routine of many people. Sometimes, mate is shared socially. In that case, the person who prepares it — “the chef” — positions the bombilla, adds the yerba and taps the cup in the palm of their hand to arrange the leaves around the straw. Once it’s ready, you don’t touch anything — especially the bombilla — as it will disrupt the brew.
I’ve recently learned that you pour the water onto the yerba, but not over all of it, keeping part of the yerba dry so the mate lasts for future rounds. And if you say thank you when it’s passed to you, or after you’ve finished drinking, it means you’re done, and the cup won’t come back to you.
The drink is typically made using a flask of hot water, which is added to the cup holding the yerba. The water needs to sit between 70 and 80 deg C. If it’s too hot, it burns the yerba, making it sharp and sour; too cold, and it won’t infuse properly. Once poured, don’t let it sit for too long, as the drink can sour quickly. There is a refreshing version called tereré, where a lemonade mix is poured over the yerba instead of hot water. I think this only works in very hot weather, and it doesn’t infuse the yerba in the traditional way. I’d highly recommend buying a mate set if you visit and leaning into the cultural experience. I’ll admit, I didn’t take to it on my first couple of trips, but now I’m completely hooked.

Work with the wind
The fishing can be technical, but I’ve shared weeks on the Rio Grande with people who had never fished before, and they’ve landed the biggest fish of the week.
Partly due to the river’s size, anglers who can’t necessarily cast far, or even particularly well, can still catch fish. But I always say: why spend the money on such a magnificent trip if you don’t put in a few hours beforehand refining your cast and learning about your quarry?
If you’ve watched any videos of the fishing, or spoken to someone who’s experienced it, you’ll have heard about the aggressive winds. After speaking to one of the guests during our recent week, who’d been to the lodges 22 times, 70mph was the strongest wind he’d ever experienced.
My mantra every time I visit, and whenever I’m fishing in the wind, is to work with it, not against it. In fact, when there’s no wind, it doesn’t feel fishy at all. There’s no ripple, and the last thing you want is your line making any sort of splash. That’s why Scandi lines are recommended over Skagit lines. Even if you think you’ll cast better in the wind, it’s simply not beneficial for sea-trout, which are notoriously spooky and shy.
Most of the time, you’ll have the wind at your back, so set yourself up accordingly. Sometimes, you can stop high on your forward stroke and let the wind do the rest — it will almost always carry your line further. I mostly keep everything very low, including both my back and forward stops. A good rule of thumb is to keep your casting trajectory at or below the level of the opposite cut bank, cutting under the wind with tight loops. Consider using reach mends, as they can make all the difference in preventing the wind from dragging your line out of position.
If you have time at home before you leave and the opportunity to practise in winds upwards of 30mph, grab your rod and get outside. It’s important to practise with the setup you plan to use, especially with a leader of 15 feet or longer, and to try casting in all wind directions: crosswinds, tailwinds, and headwinds — on both shoulders.

Ensure that each pool is approached with the utmost stealth
Wading is easy on shallow stone and sand beaches — you rarely enter beyond ankle depth. Ensure that each pool is approached with the utmost stealth. The only time you’ll need to wade deeper is when a more downstream presentation is required to slow your fly or flies in the channel. Normally, the guides will start you by fishing down the pool without wading. As you cover the water a second and third time, you can move in closer and switch to a dirtier approach, using heavier lines and flies.
I mostly relied on the overhead cast (single-handed), along with the snake roll and cross-body snake roll, on both my single and double-handed setups, as these are touch-and-go casts. It’s best to avoid sustained anchor casts such as the double Spey and snap casts, since the line tends to splash too much before you’ve had a chance to present your fly to the fish. When teaching the snake roll at home, I describe the movement after the lift as drawing a kidney-bean shape in the air before dropping back into the D-loop. In the wild winds of Tierra del Fuego, I squash that kidney bean into a pancake, making the cast far more aerodynamic to cut through the wind.
Fly-wise, I usually start with something light and unobtrusive like a Green Butt, a Green Machine, or a Sunray, then switch to a setup with a heavier set of flies. Most pools feature a narrow channel on the far side, which will be your main focus. The closer your fly gets to the opposite bank, the more water it covers as it swings into the middle of the river, where sea-trout tend to lie.
Rio Grande sea-trout checklist
Head guide Nahuel Stauch from Kau Tapen Lodge recommends the flies, gear and tactics for Rio Grande sea-trout.
The tackle Marina took
Rods
- Single-handed: Loop 7X 9ft 6in, 7wt
- Switch-rod: Loop 7X 11ft 6in, 7wt
- Double-handed: Loop 7X 13ft 2in, 8wt
Lines / tips
- Floating body with tips
- Intermediate body with tips
- Triple-density Scandi
- Skagit body with T-tips for big flies, high/dirty water and wind
- Polytips/Versitips
A useful tip for night-fishing: when using my single-handed rod as it starts to get dark, the RIO Trout Spey line worked brilliantly. Its long orange marker between the head and integrated running line made it easy to see when it was time to recast.
Flies
- Green Machine (original green, chartreuse, or black)
- Bunny Leeches, Zonkers, Intruders and articulated flies
- Sunrays, Collie Dogs and Monkeys
- Small Green Butt and Silver Stoat doubles (and similar)
- EMBs
- Rubber-Leg Girdle Bugs, and bead-head nymphs like Prince, Pheasant Tail, and Hare’s Ear
- Yuk Bugs
- Wooly Bugger variations including the Yellow Yummy
I bring all the above in a range of sizes and, where applicable, in weighted and unweighted variations.

What else to pack
Fishing in varying conditions (in my case, with a baby) means that packing can be a challenge. Luckily, most fishing destinations offer daily laundry service, so realistically you can bring two fishing outfits and two evening outfits and simply rotate them. These days I try to pack with a proper “fish-bum” attitude.
Although you’ll be visiting in summer, it won’t feel like it. It’s usually pretty cold, so you’ll need autumn or winter clothing most of the time. Include layers, thermals and puffer jackets.
Is there ever a flight these days without a delay or missing baggage? Because of that, we now travel with AirTags in every checked bag, each one clearly labelled in our “Find My” mobile phone application. Of course, our rod tube didn’t make it to Buenos Aires this time around due to delays, but at least we knew exactly where it was and when it was finally on its way to us. I’ve found that the best solution is to use modern travel rods. They’re usually six-piece, fit straight into your main luggage, and eliminate the need for a clunky rod tube, if you can help it.
