Every confirmed 2026 LA Halloween event and haunted house date, plus the ones currently unverified (but expected) that you should double-check before you buy tickets. Full guide inside.
Southern California’s Halloween season runs deeper than jack-o-lanterns and pumpkin patchesl though it turns out there’s plenty of room for those too.
This guide covers both sides of the season: the haunted houses and horror-first events built to scare you…
…and the family-friendly festivals, light trails, and trick-or-treat events built for people who’d rather skip the chainsaws.
Here’s what’s actually locked in for 2026, and below that, what’s expected but still waiting on an official date.

This is Delusion’s darkest and most interactive production yet, with split-path storytelling and a full 50-minute run time. Dates run September 17 through November 8. This is an 18+ experience; capacity is intentionally limited, so tickets move fast.

Carved — Descanso Gardens, La Cañada Flintridge This mile-long nighttime walk through Descanso’s gardens and woods features hundreds of real, hand-carved jack-o-lanterns lining a new route for 2026.

Organizers confirm a 2026 return with a reimagined trail, though exact 2026 dates hadn’t posted as of this writing — in 2025 the event ran late September through November 1 on select nights, so expect a similar window.

Expected, But Unconfirmed
The Hollow Haunted Maze — Redlands Located at Southern California’s largest pumpkin patch, this corn-lined maze is a known seasonal fixture, but a confirmed 2026 date range (previously reported as Fridays–Sundays, October 2–31, plus select weeknights) hasn’t been verified on the operator’s own channels yet. Recommended for ages 16+.
📍 32335 Live Oak Canyon Rd, Redlands
The 17th Door — Buena Park
Orange County’s most talked-about extreme haunt has an active ticketing page, but as of this writing it lists “2026 updates coming soon,” and third-party listings show the location as temporarily closed. Don’t book around this one until the operator posts confirmed dates.

This beloved medieval-themed home haunt has a long, well-documented history dating to 1971 and has appeared in the documentary Epic Home Haunts.

Treat any specific date claims for this address with real skepticism until confirmed directly through the haunt’s own social channels.

Mini FAQ: Halloween 2026 in Los Angeles
Are all the events on this list open right now?
No. Most run select nights or select dates starting mid-to-late September and continuing through Halloween or the first week of November. A few listed here — The 17th Door and Beware the Dark Realm on the haunted-house side — have not confirmed 2026 operation as of this publish date, and should be verified directly before you plan around them.
What’s a good family-friendly alternative if the haunted houses are too intense for my kids?
Carved at Descanso Gardens and Night of the Jack at King Gillette Ranch are both built around atmosphere and light rather than scares: no actors jumping out, no jump-scare mazes. LEGOLAND’s Brick-or-Treat and Six Flags’ Tricks and Treats are similarly daytime, low-intensity options aimed at younger kids.
What’s the best weekend to visit LA haunted houses in 2026?
Early in the season (mid-to-late September) tends to mean shorter lines and lower ticket prices at the major parks. The tradeoff is that some mazes and scare zones haven’t fully rolled out their season yet — Knott’s Scary Farm, for example, doesn’t reveal its full 2026 lineup until the August 18 Nightmares Revealed event.
Do LA haunted houses require separate tickets from regular park admission?
It depends on the venue. Six Flags Magic Mountain’s Fright Fest includes scare zones and shows with regular admission but requires a separate Haunted Attractions Pass for mazes. Halloween Horror Nights and Knott’s Scary Farm are both separately ticketed events entirely apart from daytime park admission.
