Eureka, California, United States

🇺🇸 Eureka is the principal city and county seat of Humboldt County in the Redwood Empire region of California. The city is located on U.S. Route 101 on the shores of Humboldt Bay, 270 miles (435 km) north of San Francisco and 100 miles (161 km) south of the Oregon border.

Eureka is the largest coastal city between San Francisco and Portland, Oregon. The proximity to the sea causes the city to have an extremely maritime climate with very small annual temperature differences and seasons mainly being defined by the rainy winters and dry summers, whereas nearby inland areas are much hotter in summer. It is the regional centre for government, health care, trade, and the arts on the North Coast north of the San Francisco Bay Area. Greater Eureka, one of California's major commercial fishing ports, is the location of the largest deep-water port between San Francisco and Coos Bay, a stretch of about 500 miles (805 km).

The headquarters of both the Six Rivers National Forest and the North Coast Redwoods District of the California State Parks System are in Eureka. As entrepôt for hundreds of lumber mills that once existed in the area, the city played a leading role in the historic West Coast lumber trade. The entire city is a state historic landmark, which has hundreds of significant Victorian homes, including the nationally recognised Carson Mansion, and the city has retained its original 19th century commercial core as a nationally recognised Old Town Historic District. Eureka is home to California's oldest zoo, the Sequoia Park Zoo.

Economy The economic base of the city was founded on timber and fishing and supplying gold mining efforts inland. Gold mining diminished quickly in the early years, and activities of timber and fishing have also diminished, especially in the latter decades of the twentieth century. Today, the major industries are tourism, timber (in value), and healthcare and services (in number of jobs). Major employers today in Eureka include the following governmental entities: College of the Redwoods, The County of Humboldt, and the Humboldt County Office of Education. St. Joseph Hospital is the largest private employer in Eureka.
