The Coquille River starts in the Siskiyou National Forest and flows hundreds of miles through the Coquille Valley on its way to the Pacific Ocean. Bandon, Oregon, sits at the mouth of the Coquille River on the Pacific Ocean. Before the era of railroads and later, automobiles, the steamboats on the Coquille River were the major mode of transportation from Bandon to Coquille and Myrtle Point in southern Coos County, Oregon, United States.
