Mile by mile
- 1RM 36Bear Creek RapidsII Class II on the FWP float map, just upstream of the Bear Creek Flats float-in campsite.
- 2RM 29.2Roundup RapidIII At the Highway 200 bridge by the Roundup access — 'a fun rapid that ranges from a bit technical to rowdy wave trains depending on flow' (American Whitewater). Easily scouted from Highway 200.
- 3RM 17Thibodeau RapidII-III About two miles below Whitaker Bridge — watch for the large rock right-center as the river drops (American Whitewater). Big Sky Fishing calls it the Blackfoot's best-known piece of whitewater with the safest route on the right; FWP's float map grades it Class II. Flow-dependent.
- 4RM 12.8The LedgeII A surf wave a quarter mile above Johnsrud that comes in when spring water is up — parking directly above and across the road, popular for park-and-play laps (American Whitewater).
Getting there & back
Put-in
Scotty Brown Bridge — FWP hand-launch access at the county-road bridge, the upstream end of the American Whitewater reach. Small site: parking is limited to 4 vehicles and prohibited on the county road within 300 yards of the bridge; no toilet. Day use.
Take-out
Johnsrud Park — The largest site on the river and the downstream end of the Recreation Corridor — concrete ramp, drinking water, toilets, and a reservable group picnic shelter (406-542-5500). Day use; closed in winter. On hot summer days it is a full-on beach scene, and the take-out gets very busy.
Shuttle (take-out → put-in): 28.9 mi · ≈ 30 min
