Best Fishing Spots

The Firehole River in West Yellowstone is renowned amongst avid fly-fishermen for its unique geothermal features and rich aquatic life. Here are the top spots loved by experts for fly fishing:

  • Nez Perce Creek: A tributary of the Firehole, it offers excellent opportunities to fish for brook and brown trout.
  • Lower Firehole: Starting from Midway Geyser Basin to Madison Junction, it’s the most challenging yet rewarding section, especially for brown trout.
