Cities in San Bernardino County, California

San Bernardino County is a huge, varied part of Southern California, stretching from dense Inland Empire neighborhoods to mountain communities and Mojave Desert towns. If you are looking for a clear San Bernardino County cities list, the key fact is simple: the county has 24 incorporated municipalities, including 22 cities and 2 incorporated towns. This guide organizes them in a practical way so you can understand not just the names, but where they sit and how they relate to the city of San Bernardino. (sbcounty.org)

What cities are in San Bernardino County, California?

The incorporated cities in San Bernardino County, California are Adelanto, Barstow, Big Bear Lake, Chino, Chino Hills, Colton, Fontana, Grand Terrace, Hesperia, Highland, Loma Linda, Montclair, Needles, Ontario, Rancho Cucamonga, Redlands, Rialto, San Bernardino, Twentynine Palms, Upland, Victorville, and Yucaipa. The county also includes the incorporated towns of Apple Valley and Yucca Valley, which are often included when people search for a list of cities in San Bernardino County CA. (sbcounty.org)

Here is a simple alphabetical list:

• Adelanto
• Apple Valley
• Barstow
• Big Bear Lake
• Chino
• Chino Hills
• Colton
• Fontana
• Grand Terrace
• Hesperia
• Highland
• Loma Linda
• Montclair
• Needles
• Ontario
• Rancho Cucamonga
• Redlands
• Rialto
• San Bernardino
• Twentynine Palms
• Upland
• Victorville
• Yucaipa
• Yucca Valley

That list is helpful for quick reference, but San Bernardino County makes more sense when you view it by region. A city like Ontario feels connected to Los Angeles County job corridors, Big Bear Lake sits in a mountain setting, and Needles is far out near the Colorado River. They are all in the same county, but they serve very different lifestyles, commutes, and local economies. For a county overview, see our San Bernardino County guide.

San Bernardino County is bigger than many people expect

San Bernardino County covers more than 20,000 square miles, making it the largest county by area in the contiguous United States. That size is the reason a basic list can feel misleading: two places can both be “in San Bernardino County” while being hours apart by car. The county includes urban communities in the San Bernardino Valley, resort and forest areas in the mountains, and desert communities across the High Desert and Morongo Basin. (main.sbcounty.gov)

For everyday use, it helps to think of the county in a few broad zones:

• Valley communities: More urban and suburban, with many cities near San Bernardino CA, major freeways, shopping centers, schools, medical facilities, and employment hubs.
• Mountain communities: Cooler, scenic areas around the San Bernardino Mountains, including Big Bear Lake and nearby unincorporated communities.
• High Desert communities: Cities and towns such as Victorville, Hesperia, Apple Valley, Adelanto, and Barstow, where land use, housing patterns, and commutes often look different from the Valley.
• Morongo Basin and eastern desert areas: Communities such as Yucca Valley, Twentynine Palms, and Needles, which connect to desert recreation, military activity, and long-distance travel routes.

This regional view is especially useful if you are researching where to live, planning a move, comparing commute options, or trying to understand which places are closest to San Bernardino itself.

Cities near San Bernardino CA

If you are searching for cities close to San Bernardino California, start with the communities that border or sit near the city in the central Valley area. Colton, Highland, Loma Linda, Rialto, Redlands, Grand Terrace, and Fontana are among the most relevant nearby incorporated places inside San Bernardino County. Each one has its own city government, neighborhoods, and local identity, even though they may feel connected across the same metro area.

Closest incorporated cities to know

• Colton: Southwest of San Bernardino, with quick access to major freeway corridors.
• Highland: East and northeast of San Bernardino, with foothill neighborhoods and access toward mountain routes.
• Loma Linda: South of San Bernardino, known regionally for its medical and university presence.
• Rialto: West of San Bernardino, part of the urban corridor that continues toward Fontana and Rancho Cucamonga.
• Redlands: Southeast of San Bernardino, with a distinct historic downtown and residential character. See Redlands real estate.
• Grand Terrace: A smaller city south of San Bernardino, positioned between the San Bernardino and Riverside areas.
• Fontana: West of San Bernardino, one of the county’s largest cities by population. (sbcounty.org) See Fontana real estate.

When people say “towns near San Bernardino,” they may also mean nearby unincorporated communities rather than incorporated cities. Areas such as Muscoy, Bloomington, Mentone, and other communities may appear in local searches or maps, but they are not part of the 24 incorporated municipalities list. That distinction matters because city services, planning rules, and local representation can differ between an incorporated city and an unincorporated county community.

The Valley cities form the county’s urban core

The San Bernardino Valley contains many of the county’s most connected and populous cities. This part of the county sits within the broader Inland Empire, with freeway access, commuter routes, logistics centers, schools, retail districts, and established residential neighborhoods. If someone is looking for cities in San Bernardino County because of work, school, healthcare, or housing, the Valley is often the first region to study.

Key Valley cities include San Bernardino, Fontana, Ontario, Rancho Cucamonga, Rialto, Redlands, Chino, Chino Hills, Upland, Highland, Colton, Loma Linda, Montclair, Grand Terrace, and Yucaipa. These places are not identical. Chino Hills is often associated with hillside neighborhoods and access to Orange and Los Angeles counties, while Ontario is a major transportation and commercial hub. Redlands and Yucaipa sit farther east, with a different feel from the denser western Valley.

For quick comparison, here are common ways to think about the Valley cities:

This is also where the phrase “cities close to San Bernardino California” becomes most useful. The nearest cities are not always the largest or best known; they are the ones that share daily traffic patterns, school and work connections, and local services with San Bernardino.

High Desert cities and towns have a different rhythm

The High Desert portion of San Bernardino County includes Victorville, Hesperia, Apple Valley, Adelanto, and Barstow. These communities are north of the San Bernardino Mountains and are connected by major desert travel corridors. They often attract attention from people comparing housing space, land availability, and commutes to other parts of Southern California.

Victorville and Hesperia are among the larger High Desert cities, while Apple Valley is an incorporated town with a more spread-out residential pattern. Adelanto has seen growth and change over time, and Barstow has long been known as a desert crossroads for travelers moving between Southern California, Las Vegas, and the Mojave region.

If you are comparing High Desert communities, consider:

1. Commute direction: A drive into the Valley can be very different from a local High Desert commute.
2. Climate: Summers, winters, wind, and elevation can feel different from the San Bernardino Valley.
3. Services and shopping: Larger cities may offer more nearby options, while smaller communities may require more driving.
4. Lifestyle expectations: Lot size, pace, and neighborhood layout can vary widely.

Mountain and resort communities add another side of the county

Big Bear Lake is the incorporated city most closely associated with the county’s mountain resort identity. It sits in the San Bernardino Mountains and is known for a very different setting than the urban Valley or desert communities. The area around it includes well-known unincorporated places such as Big Bear City, Lake Arrowhead, Crestline, Running Springs, and other mountain communities, but Big Bear Lake is the incorporated municipality on the official cities list. (psd.sbcounty.gov)

Mountain communities are important to understand because they often show up when people search for towns near San Bernardino. Some are not cities in the legal municipal sense, but they are still recognizable places with homes, businesses, visitors, and local services. If your goal is relocation, permitting, school districts, or public services, always check whether a place is incorporated or unincorporated before making decisions.

The mountains also change the practical questions. Weather, road access, tourism seasons, elevation, and wildfire preparedness may matter more here than they do in central Valley neighborhoods.

Desert communities stretch across the county’s eastern side

San Bernardino County extends far across the Mojave Desert, so the eastern and desert communities play a major role in the county’s identity. Twentynine Palms, Yucca Valley, and Needles are the incorporated municipalities most associated with this broad desert geography, while many nearby places are unincorporated communities.

Yucca Valley is an incorporated town in the Morongo Basin and is often discussed alongside Joshua Tree, although Joshua Tree itself is not an incorporated city. Twentynine Palms is closely associated with desert recreation and the Marine Corps Air Ground Combat Center area. Needles sits far to the east near the Colorado River and the Arizona border, making it geographically distant from the San Bernardino Valley even though it is part of the same county.

For residents, visitors, and businesses, this geography matters. Distances are longer, services can be more spread out, and regional identity may be tied more to desert highways, parks, military activity, or river access than to the Inland Empire’s urban core.

What is the difference between cities, towns, and communities here?

In this county context, “city” usually means an incorporated municipality with its own local government, while “town” can refer either to an incorporated town, such as Apple Valley or Yucca Valley, or casually to a smaller community. Unincorporated communities are places recognized by name but governed locally through the county rather than a city council. That is why some familiar places do not appear on the official list of cities in San Bernardino County CA.

This distinction can affect practical issues such as planning, code enforcement, police or sheriff service, public works, and local elections. For example, living in Redlands means dealing with the City of Redlands for many local matters. Living in an unincorporated community nearby may mean working with San Bernardino County departments instead.

A good rule of thumb is simple: if you need official information, search by the exact place name plus “city,” “town,” or “San Bernardino County.” That will usually clarify whether the place has its own municipal government or is part of the unincorporated county area.

A practical way to use the San Bernardino County cities list

A list is most useful when it helps you make a decision. Whether you are researching a move, planning service areas, organizing local content, or studying the Inland Empire, sort the cities by purpose rather than memorizing them alphabetically.

Use this quick checklist:

• For cities near San Bernardino CA: Start with Colton, Highland, Loma Linda, Rialto, Redlands, Grand Terrace, and Fontana.
• For larger urban and suburban centers: Review San Bernardino, Fontana, Ontario, Rancho Cucamonga, Victorville, Rialto, Hesperia, Chino, Upland, Chino Hills, Apple Valley, and Redlands.
• For High Desert options: Compare Victorville, Hesperia, Apple Valley, Adelanto, and Barstow.
• For mountain living or visiting: Look at Big Bear Lake and nearby unincorporated mountain communities.
• For Morongo Basin and eastern desert areas: Research Yucca Valley, Twentynine Palms, Needles, and nearby unincorporated communities.
• For official boundaries or services: Confirm whether the place is incorporated before relying on city-level assumptions.

This approach keeps the full list of cities in San Bernardino County useful without turning it into a confusing set of names.
