Bearmouth Access provides a developed boat ramp and parking facilities on the Clark Fork River, filling a critical gap in river access—the nearest upstream and downstream boat ramps are 19 and 18 river miles away respectively.

The site features a 12-stall gravel parking area, combination gravel and concrete boat ramp, vault latrine, and is located just north of Interstate 90 at exit 138, making it easily accessible for both fishing and paddling recreation.
