In the heart of Patagonian trout country, El Encuentro Lodge enjoys some of the world’s finest trout fishing. We enjoyed this update from the lodge which recounts highlights from the recent autumn season (which runs from early mid-March to late April) through the eyes of the guides. Read on to find out what it’s like to fish these lovely waters.
The final week of fishing season was a wet one—but just as productive as ever. Patagonia in the fall is nothing short of magical. With fresh snow on the peaks and the trees turning shades of red, yellow, and orange, it feels like nature is celebrating alongside us. Even the trout seemed to join in, with their vibrant pre-spawn colours—deep reds, golden flanks.

Fall fishing in Patagonia is a wonderful experience with the Andes receiving their first snowfall and autumn colours transforming the hillsides and river valleys. Cooler temperatures and shorter days bring out the best in Patagonia’s brook, brown, and rainbow trout populations. Migratory trout become highly active as they prepare for spawning, leading to aggressive takes on streamers and thrilling surface strikes on flying ants.

Conditions this autumn have been exceptional. Cool, crisp mornings gave way to mild afternoons, and the rivers ran cold and clean—perfect for active fish. Brown trout were especially aggressive as they prepared for the spawn, chasing streamers. Streamer fishing in the fall is prime time for targeting these migratory trout, with floating lines, sink tips, and even Trout Spey techniques delivering exciting action. Rainbows and brookies were eager on big dry flies during the warmer stretches of the day, often getting the late-season mayfly hatches. When those hatches came off, the action turned electric—sipping rises in the slicks, explosive takes in the riffles, and pods of fish working emergers just beneath the film.
There were opportunities for diverse tactics, whether wet wading or floating, guided by experts skilled in a variety of techniques, including Spey casting.

The seasonal atmosphere was remarkable: sunny days reaching 70°F (21°C) alternated with snowy days around 40°F (4°C). Interestingly, inclement weather often produced the best fishing days, rewarding anglers with unforgettable catches.
Lakes and lagoons also fished well, especially on calm, overcast days when big trout cruised the shallows. On the right afternoon, mayfly spinners clouded the still air, drawing fish tight to the edges for dramatic takes in ankle-deep water.
