How the PRG South Program Works
In Southern Patagonia, Patagonia River Guides (PRG) operates as a dedicated outfitter and guiding operation, built around local knowledge and access to a wide range of trout water throughout the region. From their base near Trevelin and Esquel, seasoned guides track conditions throughout a wide network of rivers, creeks, and lakes—selecting the water that is fishing best on any given day.
Daily fishing plans shift between waters depending on weather, water levels, and seasonal insect activity. The Río Grande, Corcovado, Corintos, Percy, and Tecka rivers are all in regular rotation, along with the clear systems flowing through Los Alerces National Park and the quieter ranch valleys around Río Pico.
By moving between several river systems rather than returning to the same stretch of water each day, PRG is able to build a week of guided Patagonia trout fishing that adapts to conditions while exposing anglers to the region’s diverse waters and landscapes. The same is true of the Patagonia River Guides North program, which rotates anglers through a broader network of estancias and lodges across Northern Patagonia.
PRG South – Guided Fishing Program Overview

- Key Waters: Río Grande, Corcovado, Los Alerces National Park rivers, Río Pico
- Fishing Style: Freestone rivers, spring creeks, and lake systems
- Program Structure: Lodge-based itineraries exploring multiple rivers
The Southern Patagonia Multi-River Trout Fishing Program
Southern Patagonia offers a markedly different trout fishing landscape from the river systems farther north. Around the towns of Trevelin and Esquel, rivers descend from the Andes through forested valleys before spreading eastward into the open grasslands of Chubut Province.
A defining feature of this region is how much water sits within reach. Clear freestone currents, glacial lake systems, and quiet ranch valleys shape the character of the fishing. With several independent watersheds located close to one another, the fishing week can move between different rivers and valleys rather than remaining focused on a single corridor.
This allows anglers to fish very different environments within the same trip, from wooded Andean river valleys to wide steppe landscapes where rivers wind quietly across open ranch country.
Trout Rivers of the Trevelin and Esquel Valleys
Several productive freestone rivers flow through the valleys surrounding Trevelin and Esquel. Waters such as the Río Grande, Corcovado, Corintos, Percy, and Tecka create classic Patagonian trout environments where clear currents run through broad valley floors bordered by forest and open grasslands.
These rivers vary in size and pace. Some wind gently across open steppe where trout hold along grassy banks and deeper bends, while others move more quickly through gravel runs and riffled channels.
Fishing along these rivers often involves covering water gradually, working through pools and runs while guides select sections suited to the day’s conditions.
Fishing the Waters of Los Alerces National Park
One of the most distinctive elements of the Southern Patagonia program is access to the waters of Los Alerces National Park, a protected Andean landscape known for its deep glacial lakes and exceptionally clear rivers.
Rivers such as the Rivadavia, Frey, Arrayanes, and Carrileufú connect a chain of lakes within the park, flowing through forested valleys beneath steep Andean peaks.
The clarity of these waters often allows anglers to see trout holding in the current before making a cast. Fishing here contrasts strongly with the open valley rivers farther east, adding another dimension to the week.
Spring Creeks and Remote Rivers of the Río Pico Region
South of Trevelin lies the quieter Río Pico region, where the Andean foothills transition into wide open landscapes dotted with ranches and small lakes. Rivers such as the Río Pico, Río Nielson, and Río Las Pampas flow through these valleys, forming smaller but highly productive trout waters.
Grass-lined banks, gentle bends, and slower currents create conditions well suited to methodical walk-and-wade fishing. The sense of space and isolation in this part of Patagonia gives the fishing week a noticeably different rhythm from the busier valleys farther north.
Float Fishing and Walk-Wade Opportunities
A week of guided angling with PRG South naturally alternates between fishing on foot and covering water by boat. Larger rivers open up through drift boat days, while smaller creeks and tributaries lend themselves to fishing on foot.
The program also includes fishing on the region’s clear lake systems, where trout are often targeted along shorelines from rafts, adding another element to the program.
Patagonia’s Southern Trout Season
The trout season across Southern Patagonia typically runs from November through April. Early in the season, snowmelt keeps rivers cold and clear, with trout feeding actively as aquatic insects begin to hatch.
During the height of summer, terrestrial insects such as grasshoppers and beetles become an important food source, and dry-fly fishing can develop steadily across the region’s rivers and creeks. As autumn approaches, cooler nights and shorter days often bring renewed feeding activity.
The Diversity of Southern Patagonia’s Waters
Within a relatively compact part of Patagonia, the range of water that can be fished is unusually broad. Freestone rivers, glacial systems, spring creeks, and quieter ranch streams all sit within reach of the same program run by the PRG team.
For anglers drawn to Southern Patagonia, this is less about fishing a single river well and more about understanding a region—moving through different waters, adjusting to conditions, and building a week shaped by variety rather than routine.
