Sonoma County California Fairgrounds Events

The Sonoma County Fairgrounds in Santa Rosa, California, serves as a gathering place for agricultural competitions, live entertainment, community festivals, trade shows, and family activities throughout the year. Known officially as the Sonoma County Event Center at the Fairgrounds, the complex brings together Sonoma County’s agricultural traditions and the region’s modern entertainment scene.

The annual Sonoma County Fair remains its signature event, with livestock exhibitions, competitive exhibits, carnival rides, food vendors, and youth agricultural programs. Beyond fair week, the grounds host concerts, horse shows, cultural celebrations, business events, and private functions.

For visitors planning a trip, exhibitors preparing entries, or vendors looking for opportunities, understanding the venue’s location, annual calendar, facilities, and participation requirements makes a visit easier to organize.

Overview of Sonoma County Fairgrounds

Location and address

The Sonoma County Event Center at the Fairgrounds is located at:

1350 Bennett Valley Road, Santa Rosa, CA 95404.

The property sits in Santa Rosa, the county seat of Sonoma County, in California’s North Bay. Its location near U.S. Highway 101 and State Route 12 makes it accessible from communities including Rohnert Park, Petaluma, Windsor, Sebastopol, and Sonoma.

The complex covers approximately 200 acres and includes exhibition halls, livestock facilities, arenas, outdoor event areas, parking, and an RV park. Its combination of indoor and outdoor spaces allows organizers to accommodate events of different sizes throughout the year.

Who operates the fairgrounds?

Sonoma County Fair and Exposition, Inc., a nonprofit organization, operates the venue under an agreement with Sonoma County. The organization manages the annual fair and year-round facility activities.

The fairgrounds’ role extends beyond entertainment. Agricultural education, youth development, local economic activity, and community gatherings remain central to its purpose.

Why the grounds matter to Sonoma County

Sonoma County is associated with vineyards, dairy farming, livestock production, specialty crops, and a strong local food culture. The fair provides a public setting where residents can see agricultural work firsthand, learn about animal husbandry, and recognize the achievements of young exhibitors.

It also creates opportunities for local artists, makers, community groups, food vendors, and small businesses to reach visitors in one central location.

Upcoming Events at Sonoma County Fairgrounds

The fairgrounds operates as a year-round event venue rather than a site that opens only for the annual county fair. Its calendar includes agricultural exhibitions, concerts, festivals, sporting events, trade shows, animal shows, and private gatherings.

Confirmed 2026 fair and event dates

The major dates announced for 2026 include:

• Sonoma County Fair: August 7–16, 2026.
• Sonoma County Harvest Fair: October 10, 2026.

The Harvest Fair provides a seasonal opportunity to celebrate the county’s wine, food, and agricultural industries. Its format and ticket arrangements may differ from those of the main summer fair.

Because individual events can change dates, hours, admission rules, or locations within the property, visitors should confirm the details with the event organizer before traveling.

What other events take place?

The grounds are used for a range of activities, including horse shows, dog shows, agricultural exhibitions, cultural festivals, concerts, expos, dances, and shopping events. The venue also accommodates weddings, corporate functions, and private celebrations.

Motorized entertainment, swap meets, flea markets, and specialized shows should not automatically be assumed to appear every year. Check the current calendar for confirmation of a particular event.

Renting space for private events

Organizers can inquire about renting indoor halls, arenas, lawns, and other event spaces. Weddings, business meetings, exhibitions, concerts, festivals, and community fundraisers are among the types of gatherings suited to the property.

Rental availability, permitted activities, insurance requirements, setup arrangements, and pricing depend on the venue and date.

The Sonoma County Fair

When is the Sonoma County Fair?

The 2026 Sonoma County Fair runs August 7–16, 2026, a ten-day summer event. This is the key annual period for visitors interested in the carnival, competitive exhibits, agricultural activities, entertainment, and fair food.

The fair’s dates can vary from year to year, so the 2026 schedule should not be treated as the permanent schedule for 2027. Future dates should be confirmed when the organizers announce them.

Livestock, flowers, arts, and competitive exhibits

Agricultural competitions and creative exhibits are important parts of the fair. Visitors can explore livestock displays, youth projects, floral arrangements, and work produced by local residents.

Competitive exhibit categories may include:

• Beef cattle, swine, sheep, goats, poultry, rabbits, and other approved livestock or small-animal entries.
• Flowers, horticulture, and garden-related displays.
• Baking, preserves, home arts, and other domestic skills.
• Photography, fine art, crafts, and handmade projects.
• Agricultural and educational displays.

Not every category necessarily accepts entries in every year. The current exhibitor guide identifies eligible classes, entry rules, judging arrangements, and submission deadlines.

Carnival rides, food, and entertainment

The fair’s carnival midway is a major attraction, with traveling amusement rides, family rides, games, and concessions. The exact ride lineup, number of attractions, ride-ticket packages, and wristband offers depend on the year’s arrangements.

Food choices typically reflect the familiar county-fair mix of fried treats, grilled food, sweets, snacks, and refreshments. Individual vendors and nonprofit food stands may vary by year.

Entertainment can include live music, special performances, agricultural demonstrations, and scheduled arena or grandstand activities. Visitors should check the daily program rather than assume a particular performer or competition is included with general admission.

Youth programs and the junior livestock auction

The fair provides young agricultural exhibitors with a chance to present animals and projects developed through supervised learning. The junior livestock auction connects those participants with buyers and community supporters.

For 2026, the announced auction schedule included:

• Friday, August 7, at 10 a.m.: lamb, goat, and small-animal auction.
• Sunday, August 9, at 10 a.m.: hog auction.
• Monday, August 10, at 4 p.m.: agricultural mechanics auction.
• Monday, August 10, at 5 p.m.: steer auction.

These dates are useful for understanding the program, but they are historical once those 2026 events have passed. Future auction schedules should be checked in the relevant year’s program.

Visitors exploring Sonoma County California Fairgrounds Events can also discover community gatherings through Solano County California Fairgrounds Events. Exploring both counties provides opportunities to discover local traditions, enjoy regional activities, and experience seasonal celebrations throughout California.

Admission, parking, and opening hours

For the 2026 fair, the published operating schedule listed gates and carnival opening at noon and closing at 9 p.m. Monday through Thursday. On Friday, Saturday, and Sunday, gates opened at 10 a.m. and closed at 10 p.m.; the carnival opened at noon and closed at 10 p.m.

Parking charges for the fairgrounds’ events generally vary by event and lot. The venue’s published guidance gives a typical range of $15–$30 for the county fair, Harvest Fair, and other year-round events unless a different arrangement is announced.

Admission prices, ride wristbands, children’s policies, senior discounts, and special free-admission periods can change. Check the relevant event’s ticket information before budgeting for a visit.

Facilities and Grounds

The approximately 200-acre complex has the scale to accommodate simultaneous indoor exhibitions, outdoor entertainment, and agricultural activities. Its facilities are also used outside the summer fair season.

Exhibition buildings and livestock facilities

The venue includes six meeting and exhibition halls, along with livestock barns, show rings, and other event spaces. Individual buildings serve different purposes depending on the event, from commercial displays and arts exhibitions to animal housing and agricultural competitions.

The grounds include facilities associated with horse shows and livestock exhibitions, as well as the Chris Beck Arena and the Lyttle Cow Palace. Exact access arrangements depend on the event and the areas being used.

Exhibitors who need animal stalls, pens, wash areas, or equipment space should obtain instructions from the fair office. Stall availability, bedding rules, arrival times, and animal health requirements are event-specific.

Arenas, grandstand, and outdoor spaces

The property includes open-air arenas, a racing grandstand, lawns, and paved event areas. These spaces can accommodate horse-related activities, entertainment, outdoor displays, and large public gatherings.

A single verified seating-capacity figure should not be assumed for the entire complex because capacity differs between venues and event configurations.

RV park, accessibility, and visitor amenities

An RV park is available at the fairgrounds, making the location useful for some visitors attending multi-day events. Reservations, rates, hookups, and stay restrictions should be confirmed with the campground before arrival.

The venue provides designated accessible parking in posted areas, with event-specific parking charges potentially applying. Visitors who need wheelchair access, accessible restrooms, mobility equipment, or other accommodations should contact the event organizer in advance.

Concessions and other services vary with the event. Do not assume that every building has an ATM, food counter, first-aid station, or public restroom available at all times.

Parking is spread across designated lots, and overflow arrangements depend on attendance and event operations.

Vendor and Exhibitor Information

Applying for a commercial vendor booth

Businesses interested in selling products, serving food, or promoting services should first establish which event fits their business. A vendor application for the annual Sonoma County Fair may differ from an application for a one-day market, festival, or trade show.

A typical application process involves:

1. Identifying the event and the appropriate vendor category.
2. Submitting the required application and business information.
3. Providing applicable permits, insurance documentation, and food-service approvals.
4. Reviewing booth fees, space dimensions, electrical requirements, setup times, and operating hours.
5. Waiting for written acceptance and payment instructions before making final arrangements.

Food vendors should verify applicable county environmental health requirements and any event-specific food handling rules. An application alone does not guarantee a booth.

Entering competitive exhibits

Residents interested in submitting artwork, photography, flowers, baked goods, crafts, or agricultural products should consult the current competitive exhibit guide.

The guide identifies eligible categories, age divisions, judging standards, entry procedures, and deadlines. Some entries may require online registration before physical delivery, while livestock entries typically involve additional documentation and animal-care requirements.

The 2026 exhibitor guide specified an entry deadline of June 30 for that year’s fair. That deadline has passed; exhibitors preparing for a future fair should confirm the next published deadline rather than rely on the previous year’s date.

Fair office contact

The main office can direct vendors, exhibitors, event organizers, and visitors to the correct department.

• Address: 1350 Bennett Valley Road, Santa Rosa, CA 95404
• Telephone: (707) 545-4200
• Published office hours: Monday–Friday, 9 a.m.–5 p.m.
• General inquiries: [email protected]

For competitive exhibits, ask for the entry office. For building and grounds questions, ask for the appropriate facilities staff. RV park inquiries can be directed to the campground at (707) 471-1700.

Getting to Sonoma County Fairgrounds

Driving from Santa Rosa and nearby cities

The fairgrounds is in Santa Rosa, so visitors traveling from downtown can follow local streets toward Bennett Valley Road. Drivers should allow extra time when a major event is drawing traffic into the area.

From U.S. Highway 101, the published directions are to take Exit 7B toward State Route 12 East, following signs toward Sonoma. Take the Downtown/South E Street exit and continue toward Bennett Valley Road. Follow posted directions and event signage for the entrance and designated parking.

Drivers approaching on westbound State Route 12 should follow the Downtown exit instructions and turn at the indicated intersection toward the fairgrounds.

From Rohnert Park or Petaluma, U.S. Highway 101 north is a practical approach. Visitors from Sebastopol can travel toward Santa Rosa using local connecting roads, while travelers from Sonoma can use State Route 12. Traffic conditions and temporary event restrictions may affect the best route.

Public transportation and rideshare

Visitors should check current Sonoma County Transit and Santa Rosa CityBus services for routes and schedules that suit their departure point. Service frequency and stops can vary, and event-specific shuttles should not be assumed unless announced.

The venue identifies a rideshare pickup and drop-off location off Maple Drive in the Median Parking Lot. Follow event staff instructions and posted signs because traffic management can change during large gatherings.

4-H and FFA at Sonoma County Fairgrounds

Youth agriculture is one of the fair’s most important educational functions. Through livestock projects, agricultural mechanics, and other supervised entries, young people learn animal care, recordkeeping, presentation, responsibility, and business skills.

4-H and local FFA participation

Sonoma County’s 4-H program offers youth opportunities to develop practical skills through projects and local clubs. Future exhibitors should contact the county’s 4-H program for information about enrollment, project requirements, and eligibility.

Future Farmers of America (FFA) chapters at area high schools also provide agricultural education and leadership opportunities. Participation in a particular fair class depends on the current rules and the student’s eligibility.

A current, verified count of participating clubs and chapters is not included here because membership and chapter participation can change.

How the junior livestock auction works

Eligible youth exhibitors present animals or agricultural mechanics projects according to fair rules. Judges evaluate entries in their designated classes, and the auction provides an opportunity for buyers and supporters to recognize participants’ work.

Buyers may include local businesses, agricultural operators, families, and community members. Prospective bidders should confirm registration, bidding procedures, payment terms, and animal disposition rules with the auction organizers.

Auction proceeds and sale arrangements can vary by project and the terms agreed with buyers. Participants should review the current auction rules rather than assume that every sale follows identical payment or ownership arrangements.

Special Events Beyond the Annual Fair

The grounds remain active outside August, providing space for activities that draw different audiences from across Sonoma County and the wider North Bay.

Seasonal festivals and agricultural gatherings

The Sonoma County Harvest Fair is a notable autumn event associated with regional food, wine, and agricultural production. Its October timing provides a different seasonal experience from the summer fair.

Other dates may feature cultural festivals, concerts, sporting events, animal shows, dances, and trade exhibitions. Horse shows and dog shows are among the types of activities associated with the venue.

Swap meets, specialized shows, and fundraisers

The grounds’ event spaces can accommodate markets, product exhibitions, community fundraisers, and specialized gatherings. However, a particular flea market, gun show, motocross competition, or rodeo should be listed as an upcoming event only after its booking is confirmed.

Community organizations planning a fundraiser or public event should contact the venue to discuss availability, permitted uses, parking, security, insurance, and event setup.

History of Sonoma County Fairgrounds

The Sonoma County Fair began in 1936, when local leaders Joseph T. Grace, Ernest Finley, Emil Kraft, and V. G. Garrett joined forces to establish a racetrack and exposition center showcasing the county’s agricultural resources.

Horse racing became an important part of the fair’s identity, alongside agricultural displays and public entertainment. Over time, the complex expanded into a multi-use venue serving a broader range of community, commercial, cultural, and private events.

The fairgrounds’ operating relationship with Sonoma County has also developed over decades. The county has contracted with Sonoma County Fair and Exposition, Inc. under similar management arrangements since 1955.

Today, the organization describes the grounds as hosting more than 200 events annually. This year-round schedule reflects the property’s development from a racetrack and agricultural exposition into a major regional event facility.

The fair has also adapted to changing community needs, including broader educational programming, modern event infrastructure, and its role as a potential resource during regional emergencies. Specific claims about record attendance, notable celebrity appearances, or individual cancellations should be tied to documented historical records rather than repeated without verification.
