II — Fly Fishing
The World's Most Diverse
Golden Dorado Fishery.
The season fills on referral before dates are announced publicly.
The water
Two river systems. Six launch points. New water every day.
At Río Mate Lodge, fly fishing is not an amenity. It is one of the core reasons the lodge exists.
We fish a vast network of remote, boat-access-only water across the Río Uruguay and Río Negro systems. Six launch points. Water that stays unpressured season after season, because we keep it that way.
Most dorado programs fish the same stretch of river every day. At Río Mate, our fishing sectors span so vast and diverse a fishery that you can explore new water every day for a week without ever retracing your path.
Big rivers. Tight channels. Hidden streams. Open lake water. Structure, current, sight-fishing opportunities, migratory fish movements. Every condition a Golden Dorado angler hopes for. All within one lodge.

02 — Four fish
Our Prized Contenders. Uruguay's four native game fish.
Four completely distinct fly fishing challenges. One river system. Each species demands a different version of you.
— I
Golden Dorado
Imagine the explosiveness of a GT, the raw aerial power of a Tarpon, and the pure aggression of a musky, built into one armor-plated predator with tiger-like jaws and zero patience for your mistakes. The golden dorado does not chase. It detonates.
— II
Blue Wolfish
A prehistoric ambush predator that detonates poppers on the surface with a violence that is genuinely hard to describe. Think pike with a bad attitude and the aggression of something that has never learned fear. The wolfish does not chase — it destroys.
— III
Pirá Pitá
South America's river salmon. Sight-fishing in clear water, dry fly eats under overhanging trees, delicate presentations on light tippets — followed by drag-melting runs that empty your reel before you process what just happened.
— IV
Wolfish
Not on anyone's bucket list. That is exactly why it matters. This prehistoric ambush predator lives in the shallow, tangled edges of private lagoons and backwater oxbows — waiting with the patience of something that has been hunting this way for millions of years.
03 — When to come
Twelve months. Four species. Pick your window.
We fish year-round. Golden dorado are available throughout the year on the Río Uruguay, while the Río Negro is a summer fishery, operating from October through March. Blue Wolfish and Pirá Pitá are seasonal species, best from October through December. Wolfish can be targeted all year long.
"Off" means we don't target the species. We fish — and the lodge is open — September through May.
Cast & Blast
Wing shooting runs alongside the river.
Dove hold on the campo every month of the year. Most guests combine a morning on the water with an afternoon in the field.
A day on the Río
From first cast to the last light on the water.
07:30
Breakfast
The table set before the day begins. Coffee, eggs, bread. The guides have been at the boats since six.
09:00
On the water
Launch from one of six private ports. Sector chosen the night before, adjusted at dawn.
13:00
Lunch
On the river, a sandbank, or back at the lodge. Open fire where the bank allows.
15:00
Afternoon session
Fishing the water closest to the lodge. Some afternoons, a siesta instead. The river is still there when you wake.
17:30
Off the water
The rod goes down. The light changes on the way back in.
19:00
Back at the lodge
Cocktails on the deck. Dinner when it's ready. The day told and retold.
03 — Why Río Mate stands apart
Uruguay has the fish. We bring the access, the scale, and the logistics that make every day count.
Scale and Range
Two river systems. Six distinctive launch points. Sixteen unique fisheries. Our purpose-built fleet — from shallow-draft jet boats to silent drift boats — puts you on a different piece of water every day of your trip. The river is never the same twice, and neither is the fishing.
Unpressured Water
The difference between pressured and unpressured water is not subtle. It shows up in the aggression of the take, the willingness to eat, and the quality of every single cast. Our guests do not just report good fishing — they report fish that behave like fish are supposed to: wild, honest, and ready.
Closer Than You Think
Land in Buenos Aires or Montevideo and you are at the Lodge the same day. No jungle transfers, no bush planes, no two-day logistics gauntlet. Uruguay runs just two hours ahead of Eastern time — you travel without jet lag and arrive rested, oriented, and ready to fish.
04 — Purpose-built access
Access is the difference between great water and fished-out water.
Reach the inaccessible
Jet Boats
Shallow rock channels and tight backcountry runs hold the most aggressive dorado in the system. Our jet boats draw inches of water and push through passages no prop boat can touch.
Command the big water
Bay Boats
Large-deck platforms built for the open river and the long fight. Stable, fast, and ready when the target is a fifteen-pound main-river beast.
The silent approach
Drift Boats
No engine noise. No wake. Just the current and the occasional shriek of a reel. Glide through skinny water, cast to undisturbed fish, wade untouched runs. Pure fly fishing.
Integrated technology
All motorized boats run Minn Kota Ultrex Quest trolling motors synchronized with Humminbird Helix 9 sonar. Silent electric positioning, all-day battery reliability — so you spend your time fishing, not troubleshooting gear.
What the week covers
Dedicated guide per boat, all days on the water, full loaner program (Sage and Scott rods, reels, flies). One all-inclusive rate — no gear rental fees, no fuel surcharges. A full program brief with seasonal notes and packing recommendations is sent upon inquiry.

"Truly the fly fishing experience of a lifetime. The ownership and guides have curated an incredible fishing program with a diversity of water types, landscapes and methods."
