Fly Fishing Ennis, Montana: Madison River Floats, Seasons and Local Pros
Ennis is the Madison River's float-fishing town: drift boats launch from Lyons, McAtee and Varney bridges upstream, the river runs along the east side of town, and the channels below Ennis Bridge are wade-only. Late June through September is prime, October is for browns, and Bozeman (BZN) is the closest major airport.
If you want a small Montana town where the river is the reason the town exists, Ennis is it. The Madison runs along the east edge of town with wade access close by, and the float water upstream is some of the most famous in the West. Our section-by-section guide is the Madison River page; this page is about using Ennis as your base. For the statewide view, see Fly Fishing Montana.

Rivers and Lakes Near Ennis
- Madison River float water: From Lyons Bridge down to Ennis the drift boats come out, with launches at Lyons Bridge, McAtee Bridge and Varney Bridge fishing access sites. FWP rules: Lyons to Varney is catch-and-release for trout with artificial lures only; Varney to Ennis Bridge adds barbless, single-pointed hooks and keeps rainbows catch-and-release.
- The channels below Ennis Bridge: Below town the Madison braids into channels on the way to Ennis Lake. FWP closes this stretch to fishing from boats, so it is walk-in water, with Valley Garden fishing access site north of town as the usual way in.
- Upper Madison walk-wade water: Upstream, Quake Lake outlet to Lyons Bridge is catch-and-release, artificial lures only and closed to fishing from boats. Split the week with West Yellowstone.
- Ennis Lake and Bear Trap Canyon: Ennis Lake sits below the channels; below Ennis Dam, Bear Trap Canyon is whitewater for experienced rowers only.
- Ruby River: West over the Tobacco Roots, the Ruby is a smaller river. From Ruby Dam to Alder Bridge, FWP makes brown trout catch-and-release and opens it April 1 through September 30. It is also one of the four rivers of Twin Bridges.
When to Fish Near Ennis

The channels warm quickly in August, so fish them early in the day, and check FWP waterbody closures for hoot-owl restrictions in hot years.
From the Podcast: The Madison Is No Place to Learn to Row
Missoula guide Michael Mathews told us about a spring-break road trip with his college teammates: the Bitterroot, then Dillon and the Beaverhead, then a day on the Madison. They finally let their least experienced friend take the oars, and the low, rocky Madison sent the boat bouncing off rocks a couple of times before they took him off the sticks. It is a funny story with a serious point that every Madison regular repeats: this is fast water over big rocks, so book a guided float or bring real rowing experience. On our October 1, 2024 episode with Andy Weiner, I compared wading the Madison's round cobble to walking on greased bowling balls. Hear Michael's full story in Life as a College Athlete/Fishing Bum and a Cost Effective Way Into Guiding.

Fish one dry fly instead of a two-fly rig

Ennis Fly Fishing Questions, Answered
Where can you fly fish near Ennis?
The Madison River is the reason to be here: float it from Lyons, McAtee or Varney bridges down to town, wade the boat-free channels below Ennis Bridge, or drive upstream to the walk-wade water below Quake Lake. Ennis Lake sits below town, and the Ruby River is over the Tobacco Root Mountains to the west.
When is the best time to fly fish near Ennis?
Late June through September is prime on the Madison around Ennis, starting with salmonflies and caddis and running through PMDs and hoppers. October is streamer season for browns. Summer heat can bring hoot-owl restrictions, so plan early starts in July and August and check FWP closures before you drive.
Do you need a guide to fly fish near Ennis?
Not to wade: the channels below Ennis Bridge and the upper walk-wade water are public and boat-free by rule. To float, a guide is the safe choice unless you are an experienced rower, because the Madison is fast and rocky, and FWP's tackle rules change by reach.
Is Ennis or West Yellowstone a better base?
Choose Ennis to float the Madison and wade the channels, with a quieter small-town feel. Choose West Yellowstone for the walk-wade water below Quake Lake and the park rivers. The towns share the same river, so splitting a week between them is common.
