Getting there & back
Put-in
Canadian Border — 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
Polebridge — Long bumpy drive on largely unpaved, poorly maintained road. Plan accordingly. National Park gate access has been regulated since ~2023; check current rules. Used as a take-out for the Canadian Border → Polebridge upper run and the put-in for Polebridge → Big Creek.
Shuttle (take-out → put-in): 21.8 mi · ≈ 58 min
