SONOMA, Sonoma County — October 25, 2026. Families planning Halloween in downtown Sonoma can mark Saturday, October 31, from 3 p.m. to 5 p.m. for Sonoma Spooktacular on the Plaza. The Sonoma Valley Chamber of Commerce’s 2026 event calendar describes a community trick-or-treat event around Sonoma Plaza and participating businesses. The listing identifies the event as family friendly.

Where should families go?

The Chamber’s entry places the celebration on Sonoma Plaza and encourages families to dress in costumes and visit participating businesses. A separate October 2026 regional family-events guide says visitors can pick up a trick-or-treat map at the Sonoma Valley Visitors Center in the Toscano Hotel, 453 First Street East, and then visit participating merchants. Because the information comes from published advance notices, check the Chamber and event organizer before heading downtown; the participation of any individual shop and the availability of treats may change.

Not every Sonoma County Halloween listing is in the city

The Chamber and Sonoma County event calendars also include seasonal attractions in Glen Ellen, Kenwood, Santa Rosa and other communities. These should not be confused with Sonoma Plaza’s city-center event. When planning a family afternoon, confirm the location and date for each gathering rather than treating all Sonoma Valley events as within Sonoma city limits.

How to follow Sonoma City Council decisions

Sonoma maintains a separate official CivicWeb portal for its elected Council and commissions. The city’s meeting portal says regular City Council meetings typically begin at 6 p.m. on the first and third Wednesday of each month in the Community Meeting Room at 177 First Street West, Sonoma. Its records archive lists meetings for October 7 and October 21, 2026 and makes agendas and supporting documents searchable.

Residents interested in city spending, the Housing Element, public spaces or local development can review the agenda packet before a meeting and the archived minutes or video afterward. The portal lists livestreaming through Sonoma TV and Channel 27, an option to subscribe to official updates, and a method of submitting comments or public-records requests. A posted recommendation is not evidence that Council adopted it.

Contact and useful verification

For questions about city government, Sonoma lists its municipal main telephone as (707) 938-3681. For Halloween details, consult the Chamber’s October 30–31 listings. Sonoma News will keep event notices separate from independent reports on city decisions and welcome firsthand reports and corrections.
