About Eureka
Learn more about the host city, Eureka.
Eureka is a city in Humboldt County, California. With a population of slightly over 25,000, it is the largest coastal city on the West Coast of the United States north of San Francisco and south of Portland and the center of the California North Coast. Eureka is Ancient Greek for "I have found it," and the city got its name as a hopeful statement made by miners during the California Gold Rush, but it was the timber industry that gave the town its early wealth. Now, with logging in decline, it retains the charm of that era with older Victorian buildings and the feel of an old-fashioned working town.
