Bozeman Fly Fishing in May

Fly Fishing near Bozeman in May

Spring rains and melting snow swell the rivers near Bozeman in mid-May. While the Yellowstone and Gallatin are the first to blow out, the Madison remains fishable in the warming weather through late May.

The landscape around Bozeman comes alive in May and there are few places in the west as stunning as the Gallatin Valley during the springtime.

May Highlights

  • The Mother’s Day Caddis hatch takes off on the Yellowstone River, creating a few days of epic dry fly fishing in Paradise Valley for lucky anglers. The timing of this hatch is difficult to predict as the river blows out soon after the hatch begins, so watch our fishing reports for the latest updates on this impressive hatch.
  • Nymphing and streamer fishing is a great way to target the trophy brown trout near Ennis on the upper Madison River during the pre-runoff weeks in early May.
  • When all the rivers near Bozeman do finally blow out in late May, join our Montana fishing guides for a few days of fly fishing the Missouri River near Craig, Montana.

Bozeman Fly Fishing Guide Pro Tip:

The lower Madison River Mother’s Day Caddis hatch continues into early May, angling pressure lightens as the hatch begins on the Yellowstone. Savvy anglers head to the lower Madison for evening dry fly sessions when the Yellowstone River starts to fish well too.
