Montana FWP fishing access at Raynolds' Pass on the upper Madison below Hebgen. Official FAS lot.
Montana FWP Three Dollar Bridge FAS. The homepage photograph is this reach. Boat ramp and wade access.
Upper access near the 1959 slide. Walk-in. Rugged terrain. Not an FWP FAS lot.
Popular put-in for float trips. Boat ramp and parking. Good wade access upstream and downstream of the bridge.
Good wade access with parking available. A solid midpoint access for both float and wade anglers working the upper sections.
Major access point for both float and wade fishing. Popular takeout for upper float trips and launch point for the lower section to Ennis.
Town of Ennis access. Good wade fishing both upstream and downstream. Close to shops and services in town.
Lower Madison access below Ennis. Good wade fishing with easier wading than the upper sections. Less pressure than bridge access points.
Remote canyon section. Advanced anglers only. No boat access. Steep hike in with challenging terrain but outstanding fishing for large brown trout.
Check Montana FWP for current regulations. Catch-and-release on sections. Barbless hooks recommended. Specific gear restrictions apply on certain sections. The section inside Yellowstone National Park requires a separate Yellowstone fishing permit.

The Madison is two fisheries that share a name. Above Ennis Lake you are covering broad riffle-and-run meadow water. Below the lake the wade game opens up and caddis and PMDs do more work than the salmonfly posters suggest. Build the trip around the hatch-chart fly list, the USGS gauge on this page, and Montana's season dates. We do not publish other anglers' catches or GPS.
If this is your first week on the Madison, fish the wade water first. A first float is worth a guide. Walk-up access is real on both the upper and the below-lake stretches if you already nymph. Pair this guide with the Montana destination page for lodges, shops, and neighboring rivers. For a 2026 fly box, read Best Flies for the Madison River in 2026.
The Madison River is the crown jewel of Montana fly fishing and one of the most storied trout streams in the world. Born at the confluence of the Firehole and Gibbon rivers in the heart of Yellowstone National Park, the Madison flows north and west through three distinct sections, each offering a fundamentally different fishing experience. The upper Madison inside Yellowstone Park provides easy wading on broad, shallow riffles with abundant rainbow trout and the occasional brown. Between Hebgen Lake and Quake Lake, the river takes on a tailwater character with cooler temperatures and larger fish. Below Quake Lake, the river enters the famous fifty-mile riffle that defines Madison River fishing for most anglers, a continuous stretch of fast, productive water that rarely exceeds chest depth and holds staggering numbers of rainbow and brown trout.
The lower Madison below Ennis Lake, flowing through the dramatic Beartrap Canyon before joining the Jefferson and Gallatin to form the Missouri River at Three Forks, offers a completely different experience. The canyon section is remote, rugged, and holds trophy-sized brown trout that see very little pressure. Between Ennis and the canyon, the broad valley section known as the lower Madison provides outstanding hopper fishing in summer and consistent nymphing through the shoulder seasons. The river's annual salmonfly hatch in late May and early June is one of the great spectacles in American fly fishing, as enormous stoneflies blanket the water and even the largest, most wary trout abandon caution to feed on these protein-rich insects.
What makes the Madison truly special is its accessibility and its forgiving nature. The river's broad, relatively uniform depth makes it ideal for wade fishing, and its aggressive trout population rewards good technique without demanding the hair-fine tippets and perfect presentations required on technical spring creeks. Whether drifting dry flies through the riffles on a July afternoon, swinging soft hackles through the evening caddis hatch, or bouncing nymphs along the bottom during a March bluebird day, the Madison delivers consistent, high-quality fly fishing throughout its long season. It is the river that has introduced more anglers to Montana fly fishing than any other, and it continues to earn its reputation as one of the finest trout streams on Earth.
