Grays Harbor has long been the industrial seaport of Washington's Pacific Coast and Grays Harbor County contains the major population centers of Hoquiam and Aberdeen. In addition, there are the resort communities along the sandy spit at the mouth of the harbor, such as Ocean Shores, and the charter fishing center at Westport. The Olympic National Forest covers most of the northwest part of the county.
Montesano has been the county seat for over 120 years.
