October is finally here, and that means Halloween spirit is in full swing across Orange County. Whether you love a good scare or prefer family-friendly thrills, OC offers something for everyone. Below is a roundup of top Halloween-themed places and activities you can enjoy this year — from theme parks to pumpkin patches to local trunk-or-treats and festivals.
1. Disneyland Resort – Halloween Time / Oogie Boogie Bash.
Disneyland goes all-out for fall. Halloween Time runs August 22 through October 31, 2025, bringing seasonal décor, themed food, and ambient Halloween fun at both Disneyland Park and Disney California Adventure.
One of the highlight events is the Oogie Boogie Bash — a ticketed Halloween party with trick-or-treat trails, character encounters, dance parties, and immersive shows (be sure to check which nights it’s offered).
Even on regular days, the parks are decked out in orange lighting, pumpkins, and spooky seasonal touches. If your readers are planning a Disney Halloween visit, this is a must.

2. Knott’s Berry Farm – Spooky Farm + Scary Farm.
Knott’s has two Halloween offerings: a daytime, family-friendly one and a nighttime haunt for thrill-seekers.
Knott’s Spooky Farm runs Thursday through Sunday from September 25 through October 31 (plus Columbus Day) in 2025.This is a gentle Halloween experience for younger kids: trick-or-treating around the Calico area, themed décor, shows, and festive fun (included with regular admission).
- Knott’s Scary Farm is the ominous, after-dark event held on select nights, typically September 18 to November 1, 2025. Expect haunted mazes, scare zones, live shows, and thousands of monsters roaming the park. It’s known as one of Southern California’s premier horror events.
Tickets must be purchased separately (it’s not included in a regular pass). This dual structure lets families enjoy a tamer experience by day and more intense scares by night.

Note: On October weekends, reservations are required for entry time slots.

They may also have evening “party nights” with extra effects — great for older kids or families wanting something a little more lively.
5. OC Zoo – Halloween Zoo-tacular.
Looking for a nature twist on Halloween? The OC Zoo (in Irvine Regional Park) hosts Halloween Zoo-tacular on Saturday, October 25, 2025, 10:00 a.m. to 4:00 p.m.

Tips for Visitors & Planning.
Buy ahead & check schedules: Many events (especially theme parks and pumpkin patches) sell out or require reservations.
Check age appropriateness: Scary events like Knott’s Scary Farm are intense and may not be suitable for younger kids.
Day vs. night experiences: Many parks convert from family-friendly to scary after dark.
Dress comfortably: Layers help — early evenings can get chilly, and walking between attractions is common.
Plan for parking & traffic: Big attractions can get crowded. Arrive early, carpool if possible, check for shuttles.
Check for event changes: Always verify event websites or social media closer to the date, as times, availability, or routes might adjust.
