Your local guide to free Halloween events in Cypress, Seal Beach, Los Alamitos, La Palma, and Buena Park | October 23–31, 2026
It's officially spooky season in Southern California!
The pumpkins are out, giant skeletons have taken over front yards, and we're all pretending the weather got the memo about fall.
But who needs sweater weather when there's Halloween fun to be had?
If you're looking for something to do with the family over the next week, I've rounded up some free Halloween events happening right here in Cypress and our neighboring communities.
We're talking costume contests, trick-or-treating, carnival games, and enough candy to keep your dentist busy through Thanksgiving.
And the best part? You don't have to spend a fortune to have a frighteningly good time!
1. La Palma Halloween Carnival
Saturday, October 24 | 3:30–6 PM
Where: Central Park, 7821 Walker Street, La Palma
Admission: FREE
La Palma knows how to throw a Halloween party!
Their annual Halloween Carnival features games, treats, giveaways, and costume contests for the whole family.
And they're not stopping at the usual best-costume competition. There are categories for the funniest, most original, spookiest, best duo, and even pets!
So if your dog has been patiently tolerating that hot dog costume, here's a chance to make it worthwhile.
Food trucks will also be on-site, with food available for purchase.
2. Los Alamitos Trunk or Treat
Saturday, October 24 | 5–7:30 PM
Where: Little Cottonwood Park, 4000 Farquhar Avenue, Los Alamitos
Admission: FREE
If your little ones are ready to collect candy, Los Alamitos has them covered!
This annual community favorite features decorated trunks, trick-or-treating, costume contests, carnival games, and a free pumpkin patch while supplies last.
There are also bounce houses, a spooky train, and activities for different ages.
It's the kind of event where kids can burn off some energy before replenishing it with an impressive amount of sugar.
3. Cops N' Goblins — Buena Park
Wednesday, October 28 | 2–6 PM
Where: Buena Park City Hall, 6650 Beach Boulevard
Admission: FREE
Who says Halloween fun has to wait until the weekend?
Buena Park's Cops N' Goblins celebration offers a chance for families to enjoy a festive afternoon with local police and community members.
It's a fun opportunity to get the costumes out early and enjoy a little midweek Halloween excitement.
4. Trick or Treat on Main Street — Seal Beach
Friday, October 30 | 11 AM–4 PM
Where: Main Street, Old Town Seal Beach
Admission: FREE
Now this is one of my favorite kinds of community traditions!
The businesses along Main Street in Seal Beach welcome little trick-or-treaters for an afternoon of costumes, candy, and neighborhood fun.
Participating merchants hand out treats, giving families a chance to enjoy Halloween while exploring the shops and restaurants that make Old Town Seal Beach so charming.
Look for balloons at participating businesses.
And let's be honest, a little shopping while the kids collect candy doesn't sound like a bad afternoon!

5. Seal Beach Trunk or Treat
Saturday, October 31 | Check organizer for hours
Where: Municipal Parking Lots at Main Street and Electric Avenue, Seal Beach
Admission: FREE
Seal Beach keeps the Halloween celebrations going with its annual Trunk or Treat!
Families can enjoy decorated vehicles, costumes, and candy right in the heart of town.
It's another chance for little ones to show off their costumes before heading out for traditional neighborhood trick-or-treating later that evening.
The city's event listing contains conflicting times, so be sure to check the latest information before heading out.

6. Halloween Night Trunk or Treat — Buena Park
Saturday, October 31 | 6–9 PM
Where: Mabel L. Pendleton Elementary School, 7101 Stanton Avenue, Buena Park
Admission: FREE
Still looking for something to do on Halloween night?
Calvary Homestead is hosting a community Trunk or Treat with decorated trunks, candy, games, jumpers, and even free food.
That's right. Free candy AND free food.
I think they've figured out how to get everyone's attention!
The event is open to the community, and costumes are encouraged.
And Don't Forget Our Own Cypress Neighborhoods!
As much fun as the organized events are, I think some of the best Halloween entertainment happens right here in our neighborhoods.
Drive through Cypress this time of year, and you'll find everything from a few cheerful pumpkins to front yards that look like they hired a Hollywood special-effects department.
Giant skeletons, spooky lighting, inflatable monsters, and enough fake spiderwebs to keep an entire neighborhood of spiders unemployed.
I love seeing how creative people get!
Take a walk around your neighborhood, admire the decorations, and enjoy the season. Sometimes the best entertainment is right around the corner.
And if you know of a particularly spectacular Halloween display in Cypress, please tell me. I'd love to see it!
Happy Halloween, Cypress!
Whether you're collecting candy, exploring Seal Beach's Main Street, or enjoying a neighborhood stroll, I hope you find a little Halloween fun over the next week.
Just remember to check the organizers' websites before heading out. Dates, hours, and availability can change, especially for popular events.
And if your kids come home with more candy than they can possibly eat, well... I hear parents are pretty good at helping with that problem.
Happy Halloween!
