The headwaters of the Snake River are located in the backcountry of the Teton Wilderness near Yellowstone National Park. It’s named after its slithering nature and oxbow bends and is home to one of the few native trout species in the United States, the Snake River Cutthroat. The Snake is the ideal river for novice and beginner fishermen looking to catch fish on big dry flies. Fishing season on the Snake is generally from April 1 through October 31.
