This guidebook details the wealth of great flyfishing in Yellowstone National Park. From major rivers like the Yellowstone, Madison, Slough Creek, Lamar, Gardner, Lewis, Snake, and Firehole, down to the smallest fishable creeks and lakes, author Ken Retallic tells anglers everything they need to know about Yellowstone’s best fisheries. In addition to covering all the most famous rivers and streams, this book introduces flyfishers to waters well off the beaten path, including some lakes with grayling and trophy trout. Also includes nearly 40 detailed maps and other great travel and angling information.
