A guide to finding sober-friendly events across Contra Costa and eastern Alameda County using local calendars and community sites.

The East Bay doesn't have a single government-run events calendar, but several private and community sites fill the gap for sober-friendly events across Contra Costa and eastern Alameda County.

For Contra Costa County:

• ContraCosta.news/events — County-wide calendar with dozens of July events, from farmers markets to night markets. Submit your own event for free at contracosta.news/events.
• Contra Costa Live — Covers Antioch, Brentwood, Concord, Danville, Martinez, Oakley, Pittsburg, Pleasant Hill and Walnut Creek. Lists festivals, concerts, car shows and more at contracostalive.com.

For Eastern Alameda County:

• Alameda Post — Launched a centralized event calendar in March 2023 for Alameda-specific listings at alamedapost.com/news/alameda-posts-event-calendar-now-centralized-resource-for-all/.
• Meetup — Search Oakland and Berkeley for interest-based groups. Many are alcohol-free: board game nights, hiking groups, book clubs, creative workshops.

For Free, Sober-Friendly Events: Check ContraCosta.news/events for listings like farmers markets most weekends across both counties (Concord, Pleasant Hill, Walnut Creek, Antioch, Brentwood); summer concert series in parks (San Ramon Central Park Amphitheater, Todos Santos Plaza in Concord) family-friendly and free; night markets in Concord (July 10) and Pleasant Hill (July 3) offering food, vendors and music without bar pressure.

The Insider Tip: Start with ContraCosta.news/events for the broadest county coverage, then drill down to city-specific sites like Contra Costa Live or Alameda Post. Meetup is your best bet for recurring social groups — search by interest, not just location.
