The Mighty Yellowstone is a large powerful river that originates in the heart of Yellowstone National Park. We define the Upper Section as the stretch between Gardiner, MT and Springdale, MT. Browns and Rainbows can be found throughout this section, and the vibrant Yellowstone Cutthroat is prominent on the upper parts. This river can please all angler styles: you can throw big fluffy dry flies up underneath cutbanks, or you can throw streamers for big aggressive brown trout. Consistent Hatches keep these trout healthy and heavy. The Caddis Hatch in May and the Salmon Fly Hatch in July are not to be missed. The towns of Gardiner and Livingston carry all the supplies you need with plenty of lodging in the area.
