the River
Meets the Sky
The Gallegos River is a low-gradient, meandering waterway that begins at the confluence of the Rubens and Penitentes Rivers, stretching approximately 112 miles before flowing into the Atlantic Ocean. Renowned worldwide as a premier Brown Trout fishery, the Gallegos attracts anglers from all corners of the globe seeking the thrill of catching these powerful and often trophy-sized trout, frequently exceeding 20 pounds.
At Karku, we fish in more than 40 carefully selected, named pools along the river, each offering unique challenges and rewarding possibilities for fly anglers.
With its ever-changing light, shifting winds, and untouched Patagonian landscape, the Gallegos is more than a river — it’s a living classroom for fly fishers. Every bend presents a new lesson in reading the stream, mastering the cast, and connecting with nature in its purest form.
From Passion to Purpose: Our Story
Karku means “the other side of the river” in the ancient Tehuelche language — a tribute to Patagonia’s native people.
Founded by Sergio and Luisa, Karku Fly Fishing grew from a tent by the river into an eco-friendly lodge that welcomes anglers from around the world.

What Our Guests Say
Every season, anglers from around the world visit Karku Camp to experience Patagonia’s wild beauty and unforgettable fishing.
Here’s what some of them have shared about their time with us.
Our week at Camp Karku this year was later in the season and the river ran high and dirty for most of the week.
Despite that, Sergio and his teams’ experience and local knowledge meant we all caught plenty of fish.
Karku is a unique place to stay. An old farmhouse on a working Estancia, it’s very different from the glitzy camps on Rio Grand and elsewhere. It appears fairly basic at first glance, but the hospitality is personal and from the heart. It is comfortable in all the best ways.
Noni’s thoughtful touches are noticeable everywhere and Anna keeps things warm and ship shape. It feels like a second home and the team so clearly love being in this special and intimate place. You can just relax and appreciate the vast beauty of this wilderness.
When you want to fish hard, Sergio and Daniel are always willing. When you feel the wind and weather are getting the upper hand, Noni keeps the delicious home made food flowing. You will not go hungry!
All in all, fantastic sea trout water and a tight knit, intimate team of great people who clearly just want to make your stay memorable. They succeeded.
The best Lodge I ever been to!
I had the opportunity to visit this beautiful place twice in the last two years and just love it. The fishing and guiding is top notch, everyone will do the best they can to give you an awesome time. Even for me as a young solo traveler I had absolutely nothing to worry about while flying down south to RGL.
I would 100% recommend this lodge and would always comeback!
Mon séjour chez Karku a été réussi du début à la fin. J’ai été accompagné par un guide passionné et très attentif, qui m’a permis de prendre des poissons tout au long de la journée, dans le cadre unique et sauvage de la Patagonie. Le confort du lodge est remarquable, les repas sont excellents, et les moments passés autour du feu après la pêche rendent l’expérience encore plus mémorable. Une destination que je recommande vivement !!
