This small river joins the Middle Fork of the Salmon River 18.5 miles downstream of Boundary Creek. You'll need a permit to float the Middle Fork making this creek logistically difficult to do. Rapid River is only runnable the short period of time between when the road to Seafoam Guard Station is open and the flow is high enough.
