Fly Fishing
Sight Fishing & Season
Our season in the Upper Paraná runs from September through May, and it changes character as it goes. September through December is peak time for all three species: Dorado, Pacú and Pirá Pytá are all firing together and each one fights nothing like the other.
January through early March the river shifts gears and it belongs to the Dry-Fly, Pacú and Pirá Pytá take center stage (4 to 8 lbs, up to 25 in the right water), deceptively powerful for their size, pulling hard and diving for structure the second they feel the hook. With Dorado still very much in play early in the morning and late in the afternoon.
From early March through May, the spotlight swings back to Dorado (6 to 8 lbs on average, with shots at 30 lbs and up), with the biggest and most battle-tested at the end of the season showing up to hunt.
Anglers usually enjoy visual with gin-clear waters, high-adrenaline fishing using predominantly floating tropical lines and lighter setups than most other South American destinations a 9-foot, 8-weight fast-action rod for Golden Dorado and a 9-foot, 6-weight or 7-weight for the elusive Pacú and Pirá Pytá.
THERE IS NOT A WRONG MONTH TO COME, JUST A DIFFERENT WEEK, DEPENDING ON WHAT YOU ARE AFTER.
Golden Dorado
Dorado known locally as the "river tiger" has it´s prime seasons in September through December & early March through May.For anglers pursuing trophy Golden Dorado in the 20 to 30-pound class, spring September through December offers peak action as large fish actively hunt structure, drop-offs, rocks and fast channels. A second high-opportunity window opens during autumn early March through May, providing exceptional conditions to strip streamers around heavy cover.
Pacú
Dry fly takes center stage, from January through March, as summer arrives, the river transforms into a Dry-Fly paradise. Using large foam terrestrials and fruit imitations demands surgical casting accuracy. This isn’t a game for novices; it is a refined, high-stakes game of patience where only those who have mastered presentation get rewarded. Even during these warm Dry-Fly months, top-tier Dorado action remains, within reach by targeting prime feeding windows during the early morning and late afternoon hours. With an endless network of channels, flats, and timber-lined banks.
Pirá Pytá
A close cousin of the Pacú and every bit as demanding on a dry fly January through March, Known as the "Freshwater Salmon" for its powerful runs and golden-orange hues, the Pirá Pytá is a Dry-Fly specialist's dream. Patrolling the tight seams, overhanging jungle canopies, and foam lines of the Upper Paraná, these sharp-eyed surface feeders demand laser-focused casting and instant reflexes. Fooling a Pirá Pytá with a large terrestrial pattern or foam insect is not an easy task and once hooked, its lightning-fast first run and acrobatic leaps will test both your gear and your composure to the absolute limit.
