The Yellowstone River is known internationally as one of the premier trout waters in the world. With it's head waters in Wyoming gaining momentum in Yellowstone National Park, the Yellowstone River rumbles out of the Park near Gardiner, Montana. Surrounded by jagged peaks and banks lined with cottonwoods, the Yellowstone River is one of the most scenic places in Montana and a near perfect fly fishing river. The Yellowstone River is usually the last Montana river to come in to shape, and when it drops and clears just enough on the edges, the big bugs (salmon flies) and the big trout turn on. The river holds native Yellowstone cutthroat, rainbow, and brown trout.
