Fall Fly Fishing Near Gardiner
Fall is one of the most consistent times of year to fly fish near Gardiner. As summer crowds thin out and temperatures cool, the Yellowstone River settles into ideal fall conditions. Flows drop, water clarity improves, and fish spread out through longer runs and softer holding water. The area around Gardiner stays active well into October, with fall colors lining the valley and easy access both inside Yellowstone National Park and downstream toward Paradise Valley.
Day-to-day fishing in the fall depends on the weather, but patterns become predictable. Cold mornings are common, so most anglers wait for the sun to warm up the river before starting. Afternoons are typically the most productive, especially on overcast days when trout feed more confidently. Streamer fishing becomes a major focus as brown trout grow more aggressive leading up to spawning, while nymphing remains effective throughout the day. Light mayfly activity can also bring fish to the surface during calm, cloudy stretches.
Fall Highlights
- Streamer fishing on the Yellowstone River near Gardiner, Montana
- Strong nymph fishing on warming afternoons throughout Paradise Valley

Bozeman Fly Fishing Guide Pro Tip
When fly fishing in Montana near Gardiner during the fall, focus on the middle part of the day when water temperatures rise a few degrees. Streamers are a great option, but don’t overlook simple nymph rigs when fish settle into slower water. Cloud cover and stable weather often create the best conditions this time of year.

Yellowstone National Park
In the winter, Yellowstone National Park offers a very different fly fishing experience compared to the rest of the year.
Many rivers and sections inside the park are closed to protect spawning fish, but the scenery, wildlife, and quiet landscape are still a big draw for anglers staying near Gardiner.
Snow-covered valleys, fewer visitors, and open stretches near the park boundary make winter feel slow and deliberate, with fishing focused on short windows when conditions line up.
For anglers based in Gardiner, winter fishing often means targeting water just outside the park boundary rather than deep inside it. Cold temperatures, shelf ice, and limited daylight keep outings short, but on milder days the Yellowstone River below the park can fish well.
Yellowstone River
In the fall, the Yellowstone River is one of the most consistent places to fly fish near Gardiner.
Cooler temperatures and lower flows spread trout throughout the river, making longer stretches fish well as the season moves along.
Crowds thin out after summer, access is easier, and the river’s pace slows just enough to make fall days feel relaxed and productive.
Fall is also a prime time to target larger trout on the Yellowstone. As brown trout become more aggressive ahead of spawning, fish tend to hold in obvious water and are willing to move for food.
Late mornings and early afternoons are usually best once the sun warms the water, and cloudy days can extend good fishing well into the afternoon.
Depuy's Spring Creek
In the fall, Depuy’s Spring Creek remains one of the most dependable places to fish near Gardiner and Paradise Valley.
Because it’s spring-fed, the water stays clear and stable even as nearby rivers drop and cool, which keeps trout feeding on a predictable schedule.
Anglers often find the best action during the warmer parts of the day, when fish slide into feeding lanes and focus on small insects drifting by.
Fall fishing on Depuy’s is more about patience than covering water.
Trout are selective, but consistent, and the lack of summer pressure makes the creek feel calmer and more approachable.
It’s a great place to slow down, fish carefully, and focus on presentation, especially when other rivers are impacted by weather or early winter conditions.
