North Fork Flathead · Flathead Valley / Glacier National Park

Canadian Border to Polebridge

The first sub-segment of the 58-mile North Fork below the Canadian border, a long Class I-II float through the upper drainage. AW describes the upper reach as 'not considered whitewater but be alert for log jams, numerous turns, and some riffles.' The headline rapid is Upper Kintla Rapids (Class II) at mile 9.14 from the put-in. ⚠️ Two distinct wood hazards: known log-jam concentrations through the upper sub-segment, and braided channels that dead-end (a channel that looks passable from upstream can pinch off downstream — pick the main flow). Bear country — Alaska-style camping protocol. Ford Access (river-right, mile 13.46) is an alternate intermediate. Approach is via the unpaved Outside North Fork Road (CR 486) from Columbia Falls — 58 miles north to the closed Flathead/Trail Creek border station, then a short side road to the river access. Plan for a slow drive.

Notes
Flathead National Forest river access (Canadian Border Boating Site) — ~58 mi north of Columbia Falls via the North Fork Road (County Road #486 / formerly MT-486). Last access road on the U.S. side at the closed Flathead/Trail Creek border crossing. Designated parking, vault toilet, boat slide; no potable water; day-use only, no fees, 3-night camping limit, solid human waste containment required. The road north is long and unpaved in places — plan for a slow approach.
Take-out

Route
Spot a vehicle at the take-out, drive boats to the put-in, retrieve at the end of the day.
Source
Driving distance via the Mapbox Directions API; matches a standard road shuttle, not a back-road shortcut.
Permits
Camping on river-left (Glacier National Park) requires a backcountry permit from the Apgar backcountry office (includes mandatory bear-aware video). River-right is Flathead National Forest — dispersed camping allowed. Wild & Scenic Corridor regulations apply (solid human waste containment, fire pan/blanket).
Season
June–August. Peak flows in early June; low water and gravel-bar dragging by August.
Rules & regulationsvia Flathead Rivers Alliance ↗
  • Personal flotation device. A USCG-approved PFD must be carried on board for every person. Anyone 12 or under must wear a PFD while the vessel is underway.
  • Bear-resistant food storage. IGBC-approved bear-resistant food storage is required in the river corridor — this is grizzly country.
  • Human-waste containment. Self-contained or solid human-waste containment is required on the Middle and North Forks (recommended on the South Fork).
  • Fire management. Fire pans or fire blankets are required or strongly recommended; camp stoves are preferred over campfires.
  • Aquatic-invasive-species inspection. An AIS inspection (NPS and Montana FWP) is required before launching anywhere in the basin.

Safety

AmberAlways true

The North Fork shelf/rapid, river-right below Polebridge, is extremely dangerous — it does not look abnormal from upstream, and parties report it flips boats and strips gear. Scout it; treat it with serious caution.

Debra / AmyAlways true

Spring high water on the North Fork is no joke: strong current, big waves, and lethal wood. Tree roots are the worst hazard — a trained packrafter drowned pinned at a tree root in shallow water when the bow folded around her legs. Novices should wait until late June/July; one paddler aborted Ford → Polebridge less than a mile in last spring. Stop at the Polebridge Mercantile for current river updates.

The run

BrandonFlow-dependent

The Kintla rapids are the only real "technical" water up high — at lower flows just dodgy boulder gardens. Also a few very avoidable log jams.

NateAlways true

There's one small rapid on the border-to-Polebridge run: watch for a large culvert on river-right — the rapid is just past it. Stay river-left and the current carries you past with no issue.

James L.Always true

Per-segment read from a paddler who ran the whole river: Ford → Polebridge is the safest stretch; Polebridge → Big Creek has wood piles and strainer hazards to dodge; Border → Ford can be low on water but is very pretty, with one splashy wave train at Kintla Creek.

Conditions

James L.6,500 cfsRecent report

Late May 2026: a paddler floated the whole North Fork from the border at 6,000–7,000 cfs with no major obstructions — a little new wood piled up but easy to see and avoid; a raft company reported border → Polebridge clear.

Ethan400 cfsFlow-dependent

Don't run the upper North Fork much under 400 CFS — you'll be dragging. Watch the USGS gauge.

JulieFlow-dependent

The border-to-Ford section is often too shallow to enjoy in July, especially a low-snow year — many parties put in at Ford instead and take out lower (e.g. Coal Creek).

Beth1,000 cfsFlow-dependent

American Whitewater lists below 1,000 cfs as 'not recommended' on the North Fork. (Distinct from the ~400 cfs point where you're simply dragging.)

Camping

BethAlways true

Camp only on river-right. River-left is Glacier National Park and requires a permit — camping there is illegal and ticketed.

BrendonAlways true

Camping is good river-right the length of the upper North Fork. A popular spot is where Red Meadow Creek meets the North Fork. Scout your first campsite ahead and camp there the night before launching.

DebraAlways true

The Big Creek campground is reserved out from June on and its boat launch gets packed in season — Northern Flats is a better camp choice.

Logistics & rules

AmberAlways true

North Fork regulations: release bull trout (no black-tipped fin — put it back), and you are legally required to carry a portable toilet for solid waste.

Tyler threadAlways true

For North Fork multi-days, leave the hard-sided drift boats — bring rafts. 10–15-mile days are very doable; in June daylight runs from before 6am to around 10pm.

SheenaAlways true

Early season, the raft companies run training and guided floats before private boaters are out — calling their front desk is a good way to get current conditions. Wild River Adventures, Glacier Raft Co, and Glacier Guides & Montana Raft cover the Middle Fork; all the companies except Great Northern run the North Fork.

Shuttle

Annie threadAlways true

Shuttle help on the upper North Fork: Cameron Trey runs shuttles, and Jonathan Munroe runs shuttles out of Home Bottom Ranch. A Polebridge-based shuttle service has also been operating in recent summers.

Is it for you

BethAlways true

The upper North Fork float is Class III at most and can be done in about 3 days (extendable). The rapids can get tricky at certain flows but ease off as the season progresses.

ChrisAlways true

Ford to Polebridge is about 11 miles — spectacular and quiet; you can have it to yourself.

JessicaAlways true

The North Fork sees far fewer people than the Middle Fork. Anything above Big Creek is quiet; Big Creek and Glacier Rim are busier. Even putting in at Glacier Rim, traffic is much lighter than the Middle Fork.

Good to know

SheenaAlways true

The Flathead Rivers Alliance publishes a North Fork trip-planning reference — camping (Glacier NP vs Forest Service), river access, and food storage — at flatheadrivers.org.

Flathead Rivers AllianceAlways true

The Flathead Rivers Alliance posts current North Fork condition videos to their Facebook during the season — a quick way to read color and level before you drive up.

The original conversations

Haley asked

Curious about details of floating the North Fork this summer? Camping? We have heard many different things. Thanks!

SheenaThis Facebook group is a great source of info. For camping (Glacier NP vs Forest Service side), river-access stats, food storage, etc., the Flathead Rivers Alliance has a quick trip-planning reference: flatheadrivers.org.
BethThe float is a good one. Lots of camping — but make sure you camp only on the right. The left is Glacier National Park and requires a permit. This float can be done in 3 days but can also be extended if you want to chill, fish, whatever. Max Class III rapids, but at certain flows they can be tricky. Shouldn't be a problem as the season progresses. How far down do you plan to go? If you're going all the way to Blankenship, please avoid the North Fork Ledge — it can be a real boat eater and can be highly retentive. Let us know if you have other questions!
Tyler asked

Montanan looking for local advice for a June North Fork float, Ford to Glacier Rim, 10 people with various experience and boats. Can we bring drift boats or should we stick to rafts? What's the magic CFS for that float? Is averaging 10–15 miles per day realistic? Any must-see stops or suggested campsites?

CynthiaRafts! No drift boats.
DanDon't bring hard-sided boats. 10–15-mile days are very easy to do — the sun is up before 6am and sets around 10pm.

Annie asked

Need some honest advice from those of you familiar with the Flathead Canadian-border-to-Polebridge section. We'll be two 14' rafts, 2 adults and 1 kid per raft, loaded with overnight gear for a 4-day/3-night trip launching July 28. What are typical flows that time of year? Any technical sections we should know about? With the lack of snow this year, are we going too late? Suggestions for a great 2nd/3rd-night camp spot? Any leads on someone to shuttle trucks?

BrandonMight be a little boney up towards the border end of July, but probably still doable with some dragging here and there. The only "technical" spots would be the Kintla rapids, which would just be dodgy boulder gardens at those flows, plus a few very avoidable log jams. Lots of great camping everywhere river-right, and there's a shuttle guy working out of Polebridge this summer. Watch flows carefully as you get closer — if it gets too low, I'd recommend putting in a little lower.
AmberCameron Trey is your shuttle. Watch out for the North Fork shelf/rapid — river-right below Polebridge. It leaves no survivors. No joke, you will be flipped, and it doesn't look abnormal from upstream, so once you hit it… goodbye gear and friends. Never camp river-left — that's Glacier Park, illegal, and you'll be ticketed. Release only bull trout — no black-tipped fin, put it back. You must, by law, carry a portable toilet for solid waste.
KathrynWe floated in pack rafts a few years back, June 1-3, from the border to Blankenship bridge. It was excellent. Border to Polebridge is great and easy. We winged the campsites — pull out and look around, just make sure it's not private land. Have a map.
BrendonBorder to Polebridge is easily done in a couple days, so consider going further. With this snowpack and early runoff it may be boney closer to the border — still doable but you may wade a little. Check USGS flows for averages. I recommend scouting your first campsite ahead, camping there the night before you launch, then floating in. I typically float border-to-Ford, then Ford-to-Sondreson for a shorter day, then Sondreson-to-Polebridge, then Polebridge-to-Coal Creek — easily four days of floating.
RoseJonathan Munroe runs shuttles from Home Bottom Ranch.
JulieIt can be really shallow between the border and Ford in July. I'd plan to put in at Ford and get out at Coal Creek instead.
CameronI'm happy to run your shuttle.
NateWe did it last year — put in at the border on June 29. There's a side channel that was very thin; otherwise you'd drag boat and gear over the rock bar to the main channel. The Ford put-in looked very doable at those flows. I'd take out further down — 10-to-12-mile days are perfect. There is one small rapid on river-right: you'll see a large culvert on river-right, and just past it is the rapid. Stay river-left and the natural current takes you right past it with no issue. Expect a few strainers from the winter.
PaulMy suggestion for a family trip that time of year: skip the upper section and do Polebridge down. There's a lot more water, lots of great camping, and you can make a two- or three-day trip. We're likely to have low water this year — not much snow.
ToniaBorder to Ford is often too low that time of year, unless you really like carrying your boat.
LukeGo all the way to Blankenship bridge. Boney up top, and the Ledge on the last day — stay far river-left on the Ledge.
BrianBorder to Big Creek. Camp where Red Meadow Creek connects with the North Fork. Nothing technical.
EthanWatch the USGS flows. If I remember right, I wouldn't run it if it's reading under 400 — you'll be dragging.
DebraLast year the North Fork was so low in May we swore it was July levels. Folks coming in late July need to really check river levels — we were dragging bottom in several places in June, and we draft in 4-5 inches of water.
BenThat's going to be a lot of work in a 14-footer that time of year, especially with overnight gear. If you can go earlier or lighter, I would.
BillWould be too low for me to enjoy, and three nights of camping from Polebridge is a very slow pace.
LeeMake sure you have the river guide book.
ArtThe Shelf is a ways below Polebridge — actually just above the Glacier Rim take-out, just after the Canyon Creek culvert on river-right. It's about 1/4 mile after the culvert and easy to miss if you go river-left. For flows, use the USGS site and select median on the chart; above median should be OK. It just had a major flow way above median.
BethBelow 1000 CFS is considered "not recommended" per American Whitewater.
JessicaMy family rafts the North Fork a ton. Anything above Big Creek is not very crowded; once you get to Big Creek and Glacier Rim it's a little busier. We stick to the North Fork because there are way fewer people — even putting in at Glacier Rim, the traffic is significantly less than the Middle Fork.
DebraThe campground at Big Creek is reserved out since June and the boat launch will be packed around that time. Northern Flats is a better choice.
Jimmy asked

Shelf / charcoal rapid, North Fork Flathead, ~12,000 cfs. Nice wave train. There's a sweeper that's still there — river-left, below it on the corner. Hopefully this is the year it gets washed away.

James L. asked

Any recent beta on new log jams or strainers? Planning a float soon and wanted to check for any major obstructions from the border down. Thanks!

SheenaThe raft companies have been running training floats and guided trips for a week or so — a great resource for early-season conditions when there aren't many private floaters out. Calling their front desk usually gets you updates: Wild River Adventures, Glacier Raft Co, Glacier Guides & Montana Raft, and Great Northern for the Middle Fork; all the companies except Great Northern for the North Fork.
MelissaJust spoke to a local raft company who ran border down to Polebridge this past weekend — they said it was clear.
James L.We floated the whole river from the border with no difficulties at 7000–6000 cfs. Watch out for wood — a few trees dangling from the banks and a few up side channels that you want to stay away from — but the main channel is generally obvious and clear. Little bit of new wood piled up in a few places, easy to see and avoid.
James L.Ford to Polebridge is probably the safest stretch. Polebridge to Big Creek has some wood piles to avoid and strainer hazards. The border to Ford may lack water but it's very pretty and has one wave train at Kintla Creek that's splashy.

Chris asked

New to the area and looking at trying out a pack raft, thinking Ford to Polebridge on a Saturday morning. I've kayaked a bit but consider myself a river novice. Did this stretch years ago and don't recall it being difficult. Anyone want to join with a second vehicle?

DebraThe river changes every year and every day, and there can be some bad spots. Tree roots in the water are to be avoided at all costs. One well-trained gal with a pack kayak drowned in 3 inches of water a few years ago — the front end folded around her legs in the swirling water around the tree root. Stop at the Polebridge Mercantile and ask about the latest river updates; someone there usually knows the river scene. Life jackets are mandatory.
AmyI'd be very careful on the river this time of year. Last May I set out to kayak Ford to Polebridge and had to abort less than a mile in because the current was so strong and the waves so big — it was just dangerous and I knew it. You might want to wait until late June or July.
