Wildlife and Water: The Beauty of Fly Fishing Ennis, MT in August and September

Late summer is one of the most spectacular times to experience Ennis fly fishing. The Madison River flows clear and cool through the heart of the valley, while the golden hues of early fall start creeping into the cottonwoods and willows along the banks. But it’s not just the fishing that makes August and September special—it’s the wildlife, the wide-open skies, and the slower, quieter pace of the shoulder season.

If you’re looking for a fly fishing trip that blends Montana fly fishing adventure with unmatched natural beauty, this is your time to visit Ennis, Montana, and fish the Madison River with the Tackle Shop’s experienced guides.

Fly Fishing Meets Wildlife Viewing on the Madison River

August and September on the Madison River offer more than trout. Our guides often say that if you keep your eyes on the water, you’ll catch fish—but if you look up, you’ll catch a show.

Late summer is prime time for:

  • Bald eagles and ospreys diving for fish right alongside you.

  • White-tailed deer crossing side channels at dawn.

  • Elk bugling in the hills as the first hints of rut begin in late September.

  • Occasional sightings of moose along the sloughs and oxbows.

  • Even black bears roaming the riverbanks as they fatten up for winter.

Our guides at The Tackle Shop love to point out these encounters while keeping you on fish. There’s something about hearing a bull elk bugle across the valley while casting to rising trout that reminds us why we live and fish here.

Fishing Opportunities in Late Summer

Of course, the fishing is still the main event. In August, terrestrial season is in full swing. Expect explosive eats on hoppers, ants, and beetles, especially during midday when the grasshoppers are most active.

As September rolls in, the days cool and Tricos, Baetis, and the early October Caddis begin to show. It’s also a great time to start throwing streamers for aggressive pre-spawn browns.
