Sol Duc [1] is legendary for its steelhead fishing in winter, plus year-round chinook and king salmon fisheries. Avoid the hassle of schlepping your own gear and schedule a trip with Piscatorial Pursuits (800/347-4232, www.piscatorialpursuits.com [2], $300 per person per day), which provides guidance based on years of reading the river, a boat, and all the tackle necessary to land one for the record books. The guide even cleans the fish for you.
