California County Seats

For each county, there is a county seat, or capital, where the local government is housed. The county seat is in charge of the general administration of the county, and the duties include; tax collection, public health, law enforcement, social services, as well as many other responsibilities.

Two Major Counties and cities

Los Angeles County, is quite well known, and is home to the city of the same name. City of Los Angeles (LA) is popular throughout the world as it is home to the US entertainment industry. The population of the county is more than 10 million people, and nearly half of them live in LA proper.

Many visitors to LA want to see the Hollywood neighborhood that is known to be the center of the motion picture industry. You can also drive through Malibu, the posh beach neighborhood west of downtown, and you'll find yourself surrounded by surf and cliffs.

In Northern California, lies one of the US’s most loved and visited cities, the City by the Bay, San Francisco (SF). Few cities live up to their hype, but SF does. Stunning vistas, cool weather, and home to a diverse and tolerant community, make SF a top US and World visitor destination.

Ride a Cable Car, eat or shop in Chinatown, or visit Fisherman’s Wharf, all in day. But a dive deeper into the city to experience great restaurants, wonderful art, and a vibrant nightlife.

County Sizes

We talked about the big, but when it comes to California you'll actually never find anything small. Even the county with the smallest area has a huge heart. And that is the City and County of San Francisco. Even with an area of 47.9 square miles, this is home to a population of over 800-thousand people. San Francisco is the second most densely populated city in the United States, the first being New York City.

Places to Visit and Things To Do

For many, no trip to SoCal is complete without seeing Disneyland. A top-rated place for a family vacation, visitors can have a blast with the attractions and live the magic of Disney – giving kids of all ages, meaning adults too, memories for life.

Other options include; getting blown away by the magnificent views of the Palm Springs Aerial Tramway, or enjoying the beauty of nature in Yosemite. Get to know the San Francisco Bay, or visit the stars at the Universal Studios in Hollywood.
