Its primary population centers of Eureka, the site of College of the Redwoods main campus, and the smaller college town of Arcata, site of Humboldt State University, are located adjacent to Humboldt Bay, California's second largest natural bay. Area cities and towns are known for hundreds of ornate examples of Victorian architecture.
Humboldt County is a densely forested mountainous and rural county with about 110 miles (177 km) of coastline (more than any other county in the state), situated along the Pacific coast in Northern California's rugged Coast (Mountain) Ranges. With nearly 1,500,000 acres (6,100 km2) of combined public and private forest in production, Humboldt County alone produces twenty percent of total volume and thirty percent of the total value of all forest products produced in California. The county contains over forty percent of all remaining old growth Coast Redwood forests, the vast majority of which is protected or strictly conserved within dozens of national, state, and local forests and parks, totaling approximately 680,000 acres (1,060 sq mi).
The original inhabitants of the area now known as Humboldt County include the Wiyot, Yurok, Hupa, Karuk, Chilula, Whilkut, Tsnungwe and the Eel River Athapaskan peoples, including the Wailaki, Mattole and Nongatl. Spanish traders made unintended visits to California with the Manila Galleons on their return trips from the Philippines beginning in 1565. Humboldt County was formed in 1853 from parts of Trinity County. The first recorded entry by people of European origin was a landing by the Spanish in 1775 in Trinidad.
The first recorded entry of Humboldt Bay by non-natives was an 1806 visit from a sea otter hunting party from Sitka employed by the Russian American Company. The hunting party included Captain Jonathan Winship, an American, and some Aleut hunters. The bay was not visited again by people of European origin until 1849 when Josiah Gregg's party visited. In 1850, Douglas Ottinger and Hans Buhne entered the bay, naming it Humboldt in honor of the great naturalist and world explorer, Alexander von Humboldt, and the name was later applied to the county as a whole.
The area around Humboldt Bay was once solely inhabited by the Wiyot Indian tribe. One of the largest Wiyot villages, Tolowot, was located on Indian Island in Humboldt Bay. Founded around 900 BC, it contains a shell midden 6 acres (2.4 ha) in size and 14 feet (4.3 m) deep. It was the site of the February 26, 1860 massacre of the Wiyot people that was recorded by Bret Harte, then living in Union, now called Arcata. Between 60 and 200 Wiyot men, women, and children were murdered that night in the midst of religious ceremony. Tolowot is now a restricted site and a National Historic Landmark. In 2019, the island was restored to the Wiyot tribe, and is now known as Tuluwat or Duluwat island.
State historic landmarks in Humboldt County include Arcata and Mad River Railroad, California's First Drilled Oil Wells in Petrolia, Camp Curtis, Centerville Beach Cross, the city of Eureka, the town of Ferndale, Fort Humboldt, Humboldt Harbor Historical District, the Jacoby Building, The Old Arrow Tree, Old Indian Village of Tsurai, the Town of Trinidad, and Trinidad Head.
On February 5 and 6, 1885, Eureka's entire Chinese population of 300 men and 20 women were expelled after a gunfight between rival Chinese gangs (tongs) resulted in the wounding of a 12-year-old boy and the death of 56-year-old David Kendall, a Eureka City Councilman. After the shooting, an angry mob of 600 Eureka residents met and informed the Chinese that they were no longer wanted in Eureka and would be hanged if they were to stay in town longer than 3 p.m. the next day. They were put on two steamships and shipped to San Francisco. No one was killed in the expulsion. Another Chinese expulsion occurred during 1906 in a cannery on the Eel River, in which 23 Chinese cannery workers were expelled after objections to their presence. However, some Chinese remained in the Orleans area, where some white landowners sheltered and purchased food for the Chinese mineworkers until after racial tension passed. Chinese did not return to the coastal cities until the 1950s.
According to the United States Census Bureau, Humboldt County encompasses 4,052 square miles, 3,568 square miles of which is land and 484 square miles is water.Cape Mendocino is the westernmost point in California (longitude 124 degrees, 24 minutes, 30 seconds). Humboldt Bay, the only deep water port between San Francisco and Coos Bay, Oregon, is located on the coast at the midpoint of the county.
Humboldt County contains a diversity of plant and animal species, with significant forest and coastal habitats. In coastal areas there are extensive amounts of redwood forests. A prominent understory shrub is the toyon, whose northern range limit is in Humboldt County.
Humboldt County's major rivers include (in order of flow-cubic meters per second-from largest to smallest):
The smaller rivers include Redwood Creek, significant due to amount of its flow; the Van Duzen; the Eel River syncline group composed of the South Fork, the North Fork, and the Salt River; the Mattole, Salmon, Elk, Bear, and Little rivers.
Historically, Humboldt County and the entire far north coast have had many earthquakes over 6.0 magnitude.
The 1992 Cape Mendocino earthquakes were a series of three major earthquakes that occurred off the coast of Cape Mendocino, California on April 25 and 26, 1992, the largest being a 7.2. Ninety-five people were injured and property in the county sustained considerable damage.
The coastal zone of the county experiences very wet, cool winters and dry, mild foggy summers. In the winter, temperatures range from highs of 40–59 °F (4–15 °C) to lows of 32–49 °F (0–9 °C). Coastal summers are cool to mild, with average highs of 60–69 °F (16–21 °C) and frequent fogs. Coastal summer temperatures range from highs of 64–70 °F (18–21 °C) to lows of 46–55 °F (8–13 °C). In the populated areas and cities near the coast, the highest temperatures tend to occur at locations just a few miles inland from Eureka and Arcata, in towns like Fortuna, Rio Dell, and smaller unincorporated communities located somewhat further away from Humboldt Bay. In these locations summer highs are 70–75 °F (21–24 °C). The coastal zone experiences a number of frosty nights in winter and early spring, though snowfall and hard freezes are rare. Coastal winters are cool and wet. Winter rainstorms are frequent, with averages from 30 inches (760 mm) to 100 inches (2,500 mm) a year varying with elevation.
Inland areas of the county also experience wet, cool winters. Snowfall is common at elevations over 3,000 ft (910 m) throughout the winter months, and is even deep enough at higher elevations to have inspired the opening (now defunct) of a small ski lift operation on Horse Mountain, near Willow Creek, for several decades in the late 1900s. Summer displays the sharpest difference between the coastal and inland climates. Inland regions of Humboldt County experience highs of 80–99 °F (27–37 °C) depending on the elevation and distance from the ocean. Occasional summer highs of 100 °F (38 °C) are common in eastern and southern parts of the county including Orleans, Hoopa, Willow Creek, Garberville, Honeydew, and inland river valleys.

Humboldt County children are at greater risk of dangerously elevated blood lead levels than Flint, Michigan's - and almost double that of any other California county measured. The cases are concentrated in Eureka's Old Town and downtown areas.
Humboldt County is known for its impressive redwood trees, and many acres of private redwood timberland make Humboldt the top timber producer in California. The lush river bottoms adjacent to the ocean are for producing rich, high-quality dairy products. Somewhat more inland the warmer valleys have historically produced abundant apples and other fruit. More recently vineyards have been planted in the Trinity, Klamath, Mattole and upper Eel river.

Humboldt County is known for its quality family operated dairy farms. The Humboldt Creamery, a significant producer of high grade ice cream and other dairy products, still operates from the original headquarters located at Fernbridge adjacent to the Eel River.
As part of the Emerald Triangle, Humboldt County is known for its cultivation of Cannabis, estimated to be worth billions of dollars. Proposition 215 allows patients and caregivers who are given a doctor's recommendation to legally (State level only) grow up to 99 plants in Humboldt County. However, in the years before Prop 215 (early 1970s – late 1980s), Humboldt County saw a large migration of the Bay Area counter-culture to the region. Many came looking to purchase cheap land, and ended-up growing marijuana to pay for their land. Especially around Garberville and Redway, the rural culture and hippie scene eventually collaborated to create a rural hippie community in which marijuana became the center of the economy and the culture. Many people prospered by producing marijuana for California and other states because of its reputation for quality. A Redway radio station, KMUD, in the past has issued warnings and alerts to the region with information on whereabouts of law enforcement on their way to raid marijuana gardens.
The Campaign Against Marijuana Planting is the multi-agency law enforcement task force managed by the California Department of Justice, formed with the prime purpose of eradicating illegal cannabis production in California. The operations began in the late 70s, but the name CAMP became used after its official establishment in 1983. While the influence of CAMP in Humboldt County has waned with decriminalization of marijuana, there is a renewed interest at the state level regarding valid growing permits and environmental concerns. As a result, CAMP is today still utilized as a policing body, in accordance with the DEA. Yearly CAMP reports, published by the California Department of Justice, Bureau of Narcotic Enforcement (BNE) are available online through Humboldt State University's Special Collections. Starting in 1983, the annual reports detail the organizational structure and names of individual participants, a summary of the season's activities, tactics, and mention of special successes, trends and hazards.
County officials and the industry have encountered challenges in the transition from an illegal, underground economy to legal recreational cannabis sales that began in California in 2018.

Election audits in the county since 2008 have used a distinctive system which has not spread elsewhere. They scan all ballots and release a file of the images with a digital signature, so candidates and the public can recount by hand or electronically to find if the official totals are correct. The first time they did this they found the official software omitted 200 ballots.

From 1920 to 1984, the county voted for the national winner of each Presidential election held within these years. Since 1988, Humboldt has been a Democratic county in Presidential and congressional elections. The last Republican presidential candidate to win a majority in the county was Ronald Reagan, a Californian, in 1984. In the late 1990s and early 2000s, Humboldt also had a substantial number of people affiliated with the Green Party, but that number has declined in recent years; however, the Green Party has had its best performance by presidential and gubernatorial candidates of any county in the United States in Humboldt County, with Jill Stein gaining her largest county-level number of votes in Humboldt in 2016.

Much of The WB's Hyperion Bay and the CBS show Blue Skies as well as an episode of Moonlighting were filmed in Humboldt County. The infamous Patterson-Gimlin film was filmed on Bluff Creek near Orleans, California.
Humboldt County has also been featured in episodes of On the Case with Paula Zahn, The Profit, Hamilton's Pharmacopeia, Top Gear, The Tonight Show with Jay Leno, Survivorman, Diners, Drive-ins and Dives, Finding Bigfoot, Treehouse Masters, Rescue 911, Walking With Dinosaurs, Somebody's Gotta Do It, Monsters Resurrected, Weediquette, Dan Rather Reports, Monster Fish, Beachfront Bargain Hunt, and many more.
Humboldt County has also been the filming location for countless national television advertisements, including many major car commercials.
In the book Lolita by Vladimir Nabokov there is a possible pun using the county's name (Humboldt) in connection to the main character's name (Humbert Humbert). This appears on page 108: "With the help of a guidebook I located [The Enchanted Hunters inn] in the secluded town of Briceland." This 'secluded town' could very well be a reference to the unincorporated Briceland of Humboldt County, making The Enchanted Hunters in 'Humboldt Land', continuing the novel's grotesque fairy-tale veneer.

Humboldt County has eight Indian reservations lying within its borders. Only four other counties in the United States have more: San Diego County, California; Sandoval County, New Mexico; Riverside County, California; and Mendocino County, California. The Hoopa Valley Indian Reservation is the largest in the state of California, a state that generally has very small reservations (although very numerous) relative to those in other states.
