Lumber has long been central to the Hoquiam Harbor economy, and local industry manufactures wood products and machine tools. Fishing and fish canning are also important to the economy.
European settlers were attracted to the future Hoquiam Harbor area by the massive virgin forest. Hoquiam Harbor developed quickly after first settlement as a lumbering center.
In 1897, sawmill operator Robert Lytle built Hoquiam Castle, listed on the National Register of Historic Places and a 929-square meter (10 thousand square foot) 20-room mansion that sports original wood paneling, cut crystal chandeliers, and stained glass windows. Today, the mansion is a popular bed and breakfast.
