Humboldt County is located on California 's northern coast, with the city of Eureka , located centrally on the coast, about 300 miles north of San Francisco and 100 miles south of the Oregon border.  Most of our visitors choose to travel to the Redwood Coast by car to enjoy the spectacular scenery all around us.

Driving time from the San Francisco Bay Area is five or six hours of spectacular scenery through Sonoma , Mendocino and Humboldt Counties .  Drive time from Portland is seven hours.

The main route to and from the Redwood Coast is U.S. Highway 101 which parallels—and in Humboldt County , touches—the Pacific Ocean . Further inland, Interstate 5 north takes you up California 's Central Valley and provides access to the coast via Highway 20 at Williams and Highway 299 at Redding .  Traveling south from Portland , take Highway 199 at Grants Pass , in Oregon .

The Eureka/Arcata airport (ACV) is served by three air carriers, United Express, Alaska/Horizon and Delta (beginning June 2008)  with daily flights from San Francisco , Sacramento , Los Angeles , Portland and Salt Lake City  . The airport is located in the town of McKinleyville , 16 miles north of Eureka .
