Arcata is a city adjacent to the Arcata Bay (northern) portion of Humboldt Bay in Humboldt County, California.
Arcata is the site of Humboldt State University, the northernmost campus of the 23-campus California State University system. With a student body equaling nearly half the city's total population, Arcata is a classic example of a traditional "college town".
The heart of Arcata is the Plaza. In the 1850s the Plaza was where goods destined for the Trinity County mines were loaded onto mule trains. The Plaza has a green lawn, extensive flower plantings, and at its center a statue of President McKinley. The Plaza is surrounded by stores, bars, coffee shops, restaurants, and live music venues.
