River Description
The Big Blackfoot River is a wonderful river for many types of river enthusiasts. In the spring the run is a friendly and fun class II/III whitewater run. Highlights include Thibedeaux Rapids in the middle of the run, and 'The Ledge' which offers great wave surfing, loops, and even long boat enders depending on the flow. The Ledge is only in when there is a moderate spring flow. As summer wears on, the water levels drop, the Blackfoot becomes a tubing mecca for Missoulians seeking to escape the heat, especially from Whitaker Bridge to Bonner. All the while, the river remains an angling classic, which was immortalized by the book (and movie) A River Runs Through It.
The river flows through a large valley and is bordered by ponderosa pines, sage, and a healthy riparian shrub community. Paddlers often see deer, elk, eagles, osprey, beaver, and a large variety of other Montana wildlife. The river is actively managed by Montana Fish Wildlife and Parks. Montana FWP now maintains boat-in only designated campsites along the Blackfoot. To reserve a Blackfoot special-use permit, call FWP at (406) 542-5564. Permits are available for use at the sites beginning June 15.

Trip Reports
Log in to add a reportSurprisingly high flows for the time of year thanks to our early heat
Ran Scotty Brown Bridge to Johnsrud over 3 days 2 nights in packrafts. I do not recommend putting a raft in at these flows but a lightweight inflatable did great! Got out to walk a handful of times but never for very long. All sections and rapids had enough flow to pick a line through. Highly recommend for a fun II+ adventure in the fall!
The Blackfoot attracts a large number of tubers, rafters, swimmers, anglers, and paddlers on hot summer days that drink a large number of canned beverages.
