In small, deep streams that get a decent amount of fishing pressure, night fishing with big flies is often the only way you are going to see a fish over 18 inches. Letting a fly sink is often impossible in snag-infested streams at night. The only option is to get a fly that rides the surface or slightly below the surface. A hand tied fly on a size 1 or 2 hook is perfect for the job. Considering you will be night fishing, there is no need to get pretty with the tying.  Fly-fishing is the type most often portrayed in magazine articles, books, and movies. Some anglers is considered the "purer" of the two forms, though there really isn't a major reason for that. This type of fly-fishing is done with a fly that will float on the surface of the water, whether it is a creek, stream, lake, or river. 

Whilst there are other ways to catch a trout on the lake and in local waterways, Patagonia Fly Fishing offers the greatest challenge and often the most fun. The winter spawning runs on rivers and streams are legendary and attract anglers from around the world. The majority of trout caught are rainbows and some anglers who have never landed a brownie simply presume that rainbows dominate the region with their cleverer (and often larger) brown trout cousins being very rare in Chile. 

You can often sight-fish to good browns as they patrol along the edges of weed beds in local lakes on sunny days gorging on insects. In fall and early winter, they head up the rivers to spawn before the more popular rainbow trout runs. It is true that brown trout fly-fishing can be harder to deceive. They often fight smarter than rainbows by using logs, rocks, and current to snag or break your line. This is what makes Brown Trout Fly Fishing in Patagonia, and indeed anywhere, so rewarding. The satisfaction of landing your first big brown trout is so much greater; and you never know you might even land a trophy!
