About Hoquiam

Hoquiam is home to more than 8,000 residents and is located on the west coast of Washington. The Port of Grays Harbor is the only deep-water port on the Pacific Ocean north of San Francisco. Residents and visitors take advantage of the proximity to the Pacific; the Grays Harbor National Wildlife Refuge, which attracts hundreds of thousands of shorebirds during their spring and fall migrations; and the Grays Harbor Farmers Market and Craft Fair, one of only two Washington State farmers markets open year-round.
