Every fall, Southern California’s theme and amusement parks transform into Halloween playgrounds. Some go heavy on the frights with haunted houses, scare zones, and gory details meant for adults, while others keep it family-friendly with not-too-scary character encounters, pumpkin displays, and mountains of candy.
This guide walks you through how each theme park in Southern California celebrates Halloween in 2026, highlights their signature seasonal events, and shares tips for making the most of your visit.
One quick note: if you’re planning to bring kids to an after-hours event, check the park’s Halloween guide first. Some of these experiences are designed to terrify even adults, and they can feel overwhelming for tweens and younger teens.
Halloween Guide to Southern California Theme Parks: An Overview
Here’s what you can expect this Halloween season across Southern California’s most popular theme parks:
- SeaWorld San Diego – Spooktacular daytime fun with trick-or-treating plus the terrifying Howl-O-Scream at night.
- Disneyland & Disney California Adventure – Halloween Time décor, special ride overlays, and the popular Oogie Boogie Bash party.

- LEGOLAND California – Brick-or-Treat Monster Party, a candy-filled celebration perfect for kids, with the all-new Brick or Treat Street.
Which Park Is Best for Halloween?
It depends on who’s going. My quick verdicts:
- Toddlers and young kids: LEGOLAND’s Brick-or-Treat, with Knott’s Spooky Farm a close second (it’s included with regular admission).
- Day and night in one park: SeaWorld San Diego, with Spooktacular included in daytime admission and the separately ticketed Howl-O-Scream after dark.
- Teens and horror fans: Universal’s Halloween Horror Nights for movie-quality scares, or Knott’s Scary Farm, the original and still one of the biggest.
- Character-loving families: Oogie Boogie Bash, if you can get tickets. Nights sell out fast.
- Coaster fans: Six Flags Magic Mountain’s Fright Fest, where the big coasters run in the dark.
Whether you’re after family fun or heart-pounding scares, this Halloween guide to Southern California theme parks highlights the best events, ticket tips, and ways to save.
SeaWorld San Diego’s Halloween Spooktacular and Howl-O-Scream
SeaWorld San Diego celebrates Halloween with two very different experiences: the family-friendly daytime Spooktacular and the after-dark fright fest Howl-O-Scream.
Spooktacular (Daytime)
On Fridays, Saturdays, and Sundays from September 11 through November 1, 2026, SeaWorld’s beloved Spooktacular takes over the park with activities included in regular admission:
- The all-new Baby Shark Halloween Show, making its California debut exclusively at SeaWorld San Diego, plus Baby Shark and Pinkfong meet-and-greets
- Dance parties, from the all-new Coral Candy Club to Spookley the Square Pumpkin’s celebration at the Waterfront
- Trick-or-treating along Captain Sweet Tooth’s Candy Trail (a reusable candy bag is required, and you can bring your own)
- Pumpkin Hunt, a scavenger-style game where guests purchase a map and search for SeaWorld animal-themed pumpkins hidden across the park. Complete it to win an exclusive Halloween prize.
Howl-O-Scream (Nighttime)
Once the sun sets, the fun takes a scarier turn. On select nights from September 11 through October 31, 2026, the park transforms into Howl-O-Scream — an intense haunt designed for mature audiences. Expect:
- Six haunted houses (two of them brand new for 2026) with elaborate sets and jump scares
- Scare zones filled with creatures of the night
- Live entertainment, headlined by the all-new Monster Stomp
- Tickets: Howl-O-Scream is separately ticketed. Current ticket options and pricing are in my SeaWorld San Diego Halloween guide.
- Hours: Begins at 7 p.m., with entry starting at 6 p.m.
Insider Tips
- The 2026 Kids Free San Diego offer is live at SeaWorld: one child ages 3–9 gets in free with a paid adult ticket through October 31.
- Save money by purchasing discounted SeaWorld San Diego tickets in advance.
Disneyland & Disney California Adventure
From August 21 through October 31, 2026, Disneyland Resort transforms into a festive Halloween wonderland. Both Disneyland Park and Disney California Adventure Park get decked out with pumpkins, themed décor, ride overlays, special food and drinks, and after-hours events that draw huge crowds year after year.
What to Expect
- Halloween décor: Hundreds of carved pumpkins line Main Street, U.S.A., and spooky touches appear throughout both parks.
- Ride overlays: The Haunted Mansion becomes Haunted Mansion Holiday, themed after Tim Burton’s The Nightmare Before Christmas. Other attractions also get Halloween twists.
- Shows and entertainment: The Halloween Screams fireworks show lights up the sky, and you’ll find plenty of Halloween-themed character meet-and-greets and trick-or-treating spots.
- Plaza de la Familia: Disney California Adventure’s celebration of Día de los Muertos returns alongside the Halloween festivities.
- Special treats and eats: The parks roll out an entire seasonal food lineup of limited-time snacks, drinks, and desserts at restaurants and kiosks across both parks.
Oogie Boogie Bash at California Adventure
The separately ticketed Oogie Boogie Bash at Disney California Adventure is the crown jewel of Disneyland’s Halloween celebrations. Guests can enjoy immersive treat trails, character encounters, exclusive shows, and themed experiences throughout the park.
- Runs 33 nights in 2026, on Sundays, Tuesdays, and Thursdays in August, September, and October, from 6 to 11 p.m.
- Tickets went on sale in June, priced from $139 to $199 depending on the night, and many nights sell out quickly. Check current availability before planning around it.
- Requires separate admission (not included with regular Disneyland tickets).
Teen-Friendly Fun
For thrill-seekers, Guardians of the Galaxy – Monsters After Dark takes over the ride in the late afternoon and evening. It’s loud, intense, and designed to be scary — a hit with teens, but not appropriate for young kids.
Insider Tips
- Plan to eat in the parks — the Halloween food lineup is outstanding, with creative treats you won’t find any other time of year.
- Ask PhotoPass photographers for special Halloween Magic Shots — they’ll add spooky surprises to your pictures.
- We have discounted Disneyland tickets. On 3-day and longer Park Hoppers, promo code SAVEMORE takes an extra $5 off per ticket below.
Universal Studios Hollywood’s Halloween Horror Nights
When it comes to horror, no one does it quite like a movie studio. Universal Studios Hollywood goes all-in for Halloween Horror Nights, running on select nights from September 3 through November 1, 2026. This is one of the most intense and immersive Halloween events in Southern California — and it’s definitely not for the faint of heart.
What to Expect
Halloween Horror Nights features:
- Movie-set-quality haunted houses based on horror’s biggest names. The 2026 lineup includes Sinners, Evil Dead Burn, Hellraiser, Killer Klowns From Outer Space, Stranger Things 5, an Ozzy Osbourne house, and Killceañera.
- The Terror Tram, which takes you through the studio backlot’s famous movie sets after dark.
- Scare zones and live shows packed with jump scares and movie-worthy special effects.
- Scare actors throughout the park — sometimes even offering surprises or themed interactions while you wait in line.
Tickets & Age Policy
- Tickets start as low as $40 on select nights when purchased online, with upgrade options available (including Universal Express and RIP tours).
- Separately ticketed event (not included with park admission).
- Not recommended for kids under 13 or for teens who aren’t into horror.
Insider Tips
- Be prepared: the makeup, special effects, and gore are incredibly realistic, making this one of the scariest theme park events anywhere.
- Buy tickets early — most nights sell out.
Discounted Universal Studios tickets are available, and Halloween Horror Nights requires its own separate ticket. My authorized store carries discounted Halloween Horror Nights admission too, including a 2 p.m. day-and-night combo ticket.
See my Universal Studios Hollywood guide to touring it and Warner Bros. Studio® on the same day.
Knott’s Berry Farm: Knott’s Scary Farm and Knott’s Spooky Farm
Knott’s Berry Farm goes all out for Halloween, offering two very different seasonal experiences: the terrifying after-hours Knott’s Scary Farm and the kid-friendly daytime Knott’s Spooky Farm.
Knott’s Scary Farm (Nighttime)
This is the original theme park Halloween event — and still one of the biggest and scariest around. On select nights from September 17 through October 31, 2026, the park transforms into a nightmare landscape filled with:
- Haunted mazes and scare zones
- Sinister live shows
- Monsters lurking in nearly every corner
There are very few scare-free zones, and monsters will sneak, startle, and chase you from the shadows. It’s a separately ticketed event, best for ages 13 and up.
- Tickets: Starting at $65
- Tips:
- Buy tickets early — this event sells out fast.
- Consider the Scary Farm Fright & Fast Lane pass to skip lines that can stretch up to two hours.
- Don’t miss the creepy-themed food and drinks like pumpkin soup, Halloween churros, candy corn funnel cakes, and cocktails with floating eyeballs.
Knott’s Spooky Farm (Daytime)
For younger visitors, Knott’s Spooky Farm offers a lighthearted way to celebrate Halloween on select days from September 24 through October 31, 2026. Designed for younger kids, this daytime event includes:
- Trick-or-treating around Calico’s shops and buildings
- Family-friendly live shows
- Costume contests and themed decorations
- Encounters with critters at Creepy Critters Corral
- Seasonal touches on family rides throughout Ghost Town
Spooky Farm activities are included with regular park admission.
Insider Tip
Save money with discounted Knott’s Berry Farm tickets.
Six Flags Magic Mountain Fright Fest
On select nights from September 18 through November 1, 2026, Six Flags Magic Mountain transforms into a full-on fright zone.
Daytime
During the day, you’ll find Halloween decorations, stage shows, and themed touches on rides — including pitch-black roller coaster experiences after dark. These elements are spooky but still manageable for families with older kids.
Nighttime (Fright Fest)
Once evening falls, the real scares begin. Zombies, ghouls, and other creatures of the night roam the scare zones, while haunted mazes and sinister set pieces take over the park. Even the roller coasters get in on the fun — and you never know when a monster might end up next to you in the seat.
Tickets & Age Policy
Fright Fest’s haunted mazes require a Haunted Attractions Pass in addition to regular park admission. Bundles that combine park admission with maze access start at $74.
- Recommended for ages 13+ — this event gets intense.
- Guests over age 12 may not wear costumes.
- Chaperone Policy: Anyone 15 or younger must be accompanied by a chaperone who is 21+ with a valid ID from 4 p.m. until closing. Check the park’s chaperone policy page for current details.
Insider Tips
- Sundays are typically the least crowded.
- Ride lines are usually shorter at night. Many guests can hit all the major attractions in about four hours without buying the Express Maze Pass.
See my Six Flags Magic Mountain guide.
LEGOLAND California Brick-or-Treat
If you’re looking for a Halloween event that’s truly designed with families in mind, LEGOLAND California’s Brick-or-Treat is the perfect fit. The event runs on select dates from September 19 through November 1, 2026, and it’s included with any park ticket dated for an event day.
What to Expect
Brick-or-Treat is packed with kid-friendly fun, including:
- Brick or Treat Street, an all-new trick-or-treat trail through six life-sized LEGO Monster homes with an interactive light trail
- Trick-or-treat candy stations throughout the park
- Costume contests for kids and groups at the V.I.M. Costume Contest
- Live shows, dance parties, and character meet-and-greets with the LEGO Monsters, including the new-for-2026 LEGO Skeleton Guy and LEGO Wacky Witch
Every 2026 date, the ticket rules, and my in-park strategy tips are in my full LEGOLAND Brick-or-Treat guide.
Insider Tips
October is part of Kids Free San Diego, and LEGOLAND has participated every year, though its 2026 offer had not posted yet as of this update (it usually appears in September). Costumes are encouraged for guests of all ages. Expect longer lines for rides and activities on Brick-or-Treat dates.
Tips When Visiting Halloween Events in Theme Parks
Halloween at Southern California theme parks is exciting, but it can also be crowded, overwhelming, and sometimes a little too scary if you don’t plan ahead. Whether you’re visiting with kids or chasing thrills with friends, these tips will help you make the most of your spooky adventure.
- Buy tickets early – Popular events like Oogie Boogie Bash and Universal’s Halloween Horror Nights often sell out weeks (or months) in advance.
- Know what’s included – Some Halloween offerings (like Disneyland Halloween Time décor or LEGOLAND’s Brick-or-Treat) are included with regular admission. In contrast, others (Knott’s Scary Farm, Fright Fest mazes, Howl-O-Scream, and Oogie Boogie Bash) require separate tickets.
- Check age recommendations – Not all events are suitable for kids. Universal, Knott’s Scary Farm, and Howl-O-Scream are best for teens and adults, while LEGOLAND, Disneyland, and SeaWorld Spooktacular cater to younger families.
- Arrive early, stay late – Crowds build fast, especially at after-hours events. Arriving at the opening and staying late gives you the best chance to experience more.
- Use skip-the-line options – Consider add-ons like Universal’s Express Pass or Knott’s Scary Farm Fright & Fast Lane to cut down on long waits for mazes and rides.
- Dress wisely – Costumes are encouraged at family-friendly events, but usually prohibited for adults at scarier nighttime haunts. Comfortable shoes are a must since you’ll be walking a lot.
- Plan for food – Seasonal treats are a highlight at many parks, from themed churros at Disneyland to creepy cocktails at Knott’s. Lines can be long, so try to eat at off-peak times.
- Bring the essentials – A light sweater for cool nights, a portable charger, and, for kids, a small trick-or-treat bag (though many parks provide them).
Final Thoughts
No matter your age or scare level, Southern California theme parks have a Halloween experience to match — from candy trails and dance parties for families to haunted mazes and late-night thrills for horror fans. Just remember: tickets sell out quickly, so plan ahead and look for discounts to make the most of your visit.
