If you've ever read Norman Maclean’s A River Runs Through It or seen the film based on the book, you know something about the grace and peace of fly fishing even if you have never cast a line. Whether you're new to the sport or an experienced angler, the Aisén River is one of the world’s best places to try fly fishing. From October to May, enthusiasts travel here from around the world to catch rainbow trout in the pools and river runs. Local guides help make the experience easy. Those who just want to watch can float down the river on a drift boat and soak up the sights of the landscape, as well as those spider threads of fishing lines glinting in the afternoon sun.
