Madison River Montana Fly Fishing

Where to Fly Fish on the Madison River, Montana (Maps, Flies and Technique)

The Madison River is a bucket list river for most fly fishers.  A promise of big trout and a beautiful mountain backdrop with easy-to-read riffles and runs.

With the headwaters at the confluence of the Firehole and Gibbons rivers within Yellowstone National Park the river flows through storybook mountain lakes like Hebgen Lake and Earthquake Lake.  

The big question to answer is where to go on the Madison River.  I consider the upper section to be the best when it comes to wading or a float trip.   This area captures what I think is the magic of the Madison.

1. Valley Garden Campground, North of Ennis

This area is mostly float fishing.  As the river flows into Ennis Lake, it becomes braided with slower flows.  Don’t get the idea you’ll be able to easily wade across this section of water.

Just south of the campground is the little secret spot that has proven to be amazing for me.  Called O’Dell Creek, please be respectful as this little honey hole runs through private property. 

2. Palisades Campground – A quick fishy float

Just upriver from Palisades Campground about a mile and a half is a boat ramp that provides a perfect short float with a chance to walk back to the put in.  I know this sounds like a lot of work, but walking a mile in Montana should be considered a treat.

I’ve written how I enjoy small waters built for canoes.  The Madison is big water here, but with a stable canoe, I’ll drop in at the boat ramp and float to Palisades campground.  Then walk back to get my vehicle.

Getting a campsite at Palisades is even better.  Fishing followed up with chilly out with a campfire with a refreshment in hand, after a grilled steak.  Nothing better.

3. Three Dollar Bridge – Park, Wade and Fish

Along 287 is a little Forest Service Road 8381 that provides access at Three Dollar Bridge.  This is wading water with a great population of browns.  During low water you can sometimes cross the river with extreme caution.

I park in the small lot just north of the bridge a hundred yards or so.  At the lot is a trail travels down river a little way which provide good access.  I like dropping down off the trail and fishing through the obvious runs and then getting back onto the trail hiking to the next run.

If something is hatching go with traditional dry flies like a caddis.  Don’t discount nymphs though, so many anglers want to toss dries, but nymphing is usually more productive.  Pheasant tails and sparkling caddis pupa have been proven winners.

4. Raynolds Pass – Wading

The bridge spanning the Madison River on Highway 87 provides a perfect spot to park, hike and wade.  This spot does get busy so expect folks casting flies along this section.  If you’ve got the legs it’s easily possible to walk and fish all the way to Three Dollar Bridge.

Lots of big boulders form pockets itching to have a fly drifted through.  A drag free drift is critical, these trout have seen lots of flies and have been learned to recognize a poor presentation.

My plan has always been to show up at 6 pm and hike to a likely spot and wait for a hatch.  The best times for me have been from 8 to 10 pm.  Caddis and PMDs have proven to be effective.  In late summer this is “Hopper” water many bugs

5. Cobblestone Access – Wading Day Trip

South of Three Forks on Madison Road is a perfect area that doesn’t get much fishing pressure, but sees quite a few kayaks and canoes. The river is braided giving you the opportunity to find holding water in and out of the trees.

Across the braids along the west side of the main channel is a deep run that has provided excellent streamer fishing. Look for the structure and cast in front and behind.

In late summer this area is a grasshopper haven. The western winds blow the hoppers off the high banks and get funneled into the many holding runs.

6. Greycliff Campground Miles of Water

Greycliff Campground is a great central location for a weeks worth of tossing flies. If you’ve got a boat, even a canoe you could probably fish even longer.

An angler can hike north for 1/4 mile and south for 1 1/2 miles and step into the river filled with wild rainbows and browns.

My favorite way of fishing this area is to drop my canoe in at the campground and float to Black’s Ford fishing access site. This provides a full day of hard fishing, stopping and fishing the fishes spots.

Guide Tip: Pack an extra travel rod. Accidents happen, For around a $100 you can get a 7-peice 5 weight fly rod with a hard travel case. My pick -> Wild Water Standard 9 Foot, 7-Peice, 5 Weight

Why is the Madison River Perfect for Fly Fishing?

Epic fishing, amazing mountain views and reliable hatches.  The Madison Valley does look stark and barren, high plains grasses and long vistas make you question the fertility of the water.  But lift a rock out of the water and you’ll see why trout thrive here.

The aquatic life in this water is enormous.  All those bugs feed hungry browns and rainbows at an accelerated rate. 

Guide Tip: Montana Fish, Wildlife and Parks maintains a great website with access points.  Find the maps HERE

The Madison is predominately a brown trout and rainbow fishery.  These are naturally reproducing fish.  Montana State manages the river for fishermen.  If you search you will find small creeks feeding the river you can find n contain cutthroat and grayling.

Favorite Flies for the Madison

Stories of huge hatches of salmon flies and golden stone fly are all over the internet, but what makes the Madison great is that reliable hatches mean it’s easy to carry the right flies.

My choices:

Favorite Flies for the Madison River
Favorite Flies for the Madison River – image UMPQUA

Stonefly in size 8-12

I like a variation to the Stimulator Stonefly with optional rubber legs.  These are high floating dries and work perfect with a dropper. 

Apply a liberal amount of fly dressing, as the choppy Madison River flows will quickly drown this fly.

Pale Morning Duns (PMD) in size 20

I love PMDs with flash and sparkle.  Mostly so I have a chance to see them because tossing dries in a size 20 or smaller requires attention in rougher water like the Madison.

Caddis fly in size 16

With hatches of caddis popping from spring to fall, you’ve got to have these in your fly box.  A solid choice is a Elk Hair Caddis that is brown. 

I enjoy tying and fishing elk hairs so I always have a variety of sizes in different color ranges in my fly box. 

Baetis (BWO) Nymphs in size 14 to 20

I’m not sure where the Pheasant Tail Nymph was invented, but it works.   Smaller sizes on the Madison work great.  I have a variety of sizes and weights.  A simple beadhead works when drifted below a high floating dry.

It’s always a good idea to snoop around at a fly shop and get the local intel.  Sometimes the trout are keyed into a particular bug and it’s tough to get a take from anything else.

Fly Rod and Reel Setup for the Madison River

The trout will come in trophy sizes on the Madison.  I recommend a flexible setup, a 6-weight 9-foot fly rod is perfect.  If you can find a 10 foot, 6 weight it would even be better.

My recommendation if you’re buying a fly rod to fish Montana Rivers is to get a Sage Foundation Combo.  Just add your flies, extra leaders and you could be fishing.  What’s even better is the awesome feeling you get when your buddies see you casting a Sage.  Check prices and reviews on Amazon with this shortcut link -> Sage Foundation Fly Rod Combo
