Tumbling down from Argentina through the heart of Chilean Patagonia, the Río Puelo is a massive, turquoise-colored river that ranks among the most spectacular and productive fisheries in South America. Fed by a network of tributary rivers and draining through the Los Lagos Region toward the Seno de Reloncaví, this freestone river carries impressive volume and surge, with a character defined by powerful riffles, deep runs, side channels, and the kind of wild mountain riverbed structure that holds large fish. Its distinctive turquoise hue and the dramatic Andean backdrop make it as visually stunning as it is productive. The Río Puelo has earned a reputation that rivals — and in many respects surpasses — well-known salmon rivers in Alaska, particularly for Chinook salmon, while simultaneously supporting a thriving population of large rainbow and brown trout. The fishing season runs from November through May, making it a premier Southern Hemisphere destination for anglers seeking trophy fish in a remote and breathtaking setting.
