The Madison River is one of the most iconic trout streams in the world, and for a good reason. Formed by the confluence of the Firehole and Gibbon rivers in Yellowstone National Park, the Madison flows through rocky canyons and broad valleys bracketed by soaring mountain peaks before joining the Jefferson and Gallatin rivers near Three Forks, Montana, to form the Missouri River. Excellent hatches and trout fishing can be found throughout, making the Madison River a must-fish destination for any serious angler.
