For Tehama County in 2026, the strongest date-specific Halloween-related listings come from the public library. The region’s official 2026 visitor guide also describes annual Kids’ Spooktacular and Treat Street traditions in Red Bluff and Corning, but does not supply exact 2026 times for those community celebrations. We identify that uncertainty rather than invent a schedule.

Editorial transparency, October 11, 2026: Not every mountain county has multiple verified holiday events. Dates are identified as confirmed, tentative, past or general fall outings to prevent misleading travel recommendations.

4. Kids’ Spooktacular — annual event, 2026 date not confirmed

Where: Red Bluff region
Dates: Usually the Saturday before Halloween; check 2026 announcement
Time: Not yet established by visitor guide

The official area visitor guide describes a free family community event with games, music and activities. This is an annual tradition, not a confirmed 2026 calendar entry with a precise time. Official or local source.

5. Treat Street — annual local tradition, 2026 details to confirm

Where: Downtown Red Bluff and downtown Corning
Dates: Halloween-season 2026; precise dates to verify
Time: Check each city’s organizers

The 2026 regional visitor guide lists free Treat Street programs in both towns, but does not supply a published start time. Contact participating downtown associations before visiting. Official or local source.

6. Corning Olive Festival — earlier fall outing

Where: Corning
Dates: October 10, 2026
Time: Festival schedule

The annual Olive Festival includes family activities but is not a Halloween event and has already occurred for 2026. Official or local source.

How to make a reliable family plan

The library workshops are the most clearly dated upcoming choices. The free Treat Street and Spooktacular traditions are worth watching but should not be promoted as confirmed until organizers announce dates and hours. Red Bluff, Corning and Los Molinos are distinct towns with separate schedules.

Travel checklist

  • Do not travel solely because a previous year’s Halloween page exists. Ask the host to confirm the 2026 program.
  • Check hours, admission and parking; ask whether costumes and young children are welcome.
  • In rural and mountain locations, check Caltrans road conditions, snow, wind and wildfire advisories.
  • For fall outings without a specific Halloween program, dress for the weather and respect local access rules.
