Río Frey flows out of the massive Lago Futalaufquen within Los Alerces National Park, a UNESCO World Heritage site in Chubut Province, Patagonia, Argentina. It stands as the largest river in the park and one of the most remote, requiring anglers to cross two lakes just to reach it. That demanding journey is precisely what keeps fishing pressure low and the trout eager. The river's remote character, combined with its position deep within one of Patagonia's most spectacular protected landscapes, makes it a genuinely special destination for fly anglers willing to put in the effort.

Río Frey is commonly paired with nearby Lago Krugger as a single day's fishing destination, with guides routing anglers through both waters to maximize variety and opportunity. The river itself, flowing from Lago Futalaufquen, offers the full range of trout habitat encountered on a float — from moving current to deeper holding pools where large browns stage. The combination of the river and the lake provides anglers with both moving-water and stillwater techniques in a single outing.
