Fly Fishing in Montana


Highlights for Each Season Listed Below


Spring (late March - May)

Low, clear waters with hungry trout gearing up for accelerating hatches

The best-kept secret of fishing in the Yellowstone area!

Other fishers few and far between, the season's first hatches and trout waking up from the long winter make for solid fishing conditions. If the weather is kind.

Spring fishing can mean snow on one day and sunny, 50-degree weather the next. You'll fish in both, so come prepared.

Fall (September through October)

Typically phenomenal weather and more streamer fishing opportunities

The "Indian Summers" in Yellowstone country may make you want to stay on the water more than any other time of year.

All while competing with far fewer anglers than peak summer.

Good hatches still make the water ripple, so you'll have plenty of trout to trick onto your line.

And if you're looking for a lunker, streamer fishing also picks up in the fall, meaning you might get that trophy brown.

Exotic destinations call, but the local fishing holds up in spring creeks

In winter, the spring creeks remain consistent for challenging subsurface nymping and stalk fishing , but it's not for everyone.

The unpredictable cold and nasty weather of winter combined make it impossible for us to book your trip far in advance, and trips are extremely limited.

But if you're in the area, please give us a call at 406-333-4401 to check conditions and trip availability.

Alternatively, you can check our trips to tropical destinations or the southern hemisphere if you'd prefer somewhere with an umbrella in your drink.
