Colusa County’s confirmed October 2026 activities include a costumed dog fundraiser, early-October pumpkin festival and a comic take on Dracula. Because there is no confirmed countywide Halloween candy parade on these organizer calendars, this guide does not present one as fact.

Updated October 11, 2026. Confirm organizer announcements for last-minute changes and do not confuse seasonal fall visits with guaranteed Halloween-night festivities.

Travel and safety tips

The Oct 24 dog-costume event is the strongest late-month themed option. The early pumpkin festival was on Oct 4 and should not be advertised as upcoming. Families may check Colusa or Williams local merchant announcements for any additional trick-or-treating, but no date is confirmed here.

Verify event dates, entry fees, parking and age restrictions. For remote counties, also check weather, road closures and fuel availability before departure. Do not rely on previous years’ schedules as proof of a 2026 event.
