Seattle has a good Halloween problem this year: October 31 lands on a Saturday, and there are enough worthwhile events to fill the entire month before it arrives. You can spend a night inside the Georgetown Morgue, watch cult horror with a room full of film fans, dress up for a massive electronic music festival, or take the kids to see animals demolish pumpkins at Woodland Park Zoo.
The surrounding area expands the choices. Nile Nightmares is back in Mountlake Terrace. Maris Farms has a haunted walk through corn and woods in Buckley. Wild Waves is hosting one last Fright Fest in Federal Way before the park closes at the end of its 2026 season. Those places involve a drive, but each offers a different kind of night than you’ll find in a Seattle club.
This is RMR’s guide to confirmed 2026 Halloween events in Seattle and the surrounding area, with the dates, locations, and practical distinctions that help you pick one. Organizers can still change hours, prices, and programming, so follow the event links when you’re ready to buy. More importantly, check the year on any page that turns up in search. A few Seattle venues still have old Halloween party pages online, and they are easy to mistake for this season’s announcement.
Seattle Halloween Events 2026
Georgetown Morgue: Seattle’s in-city haunted house pick
If someone asks for a haunted house without leaving Seattle, start with the Georgetown Morgue. It sits at 5000 E. Marginal Way South, in the industrial stretch of Georgetown where the setting helps build the mood before you enter. It’s a stronger answer to “let’s get scared tonight” than a generic Halloween party with a couple of decorations by the door.
RMR has been here before. Our earlier Georgetown Morgue review looked at what makes the attraction work, including the building and the stories attached to it. That piece is an archive, though; its descriptions should not be mistaken for a rundown of the 2026 show. The Morgue’s current website has a schedule and ticket page where you can select an operating night.
Georgetown is a good neighborhood for making this a proper outing. Get dinner before your entry time and leave enough room to find the attraction without rushing. Don’t build a complicated cross-town itinerary around a haunt ticket; a late dinner, a drive through Seattle, and a fixed admission time can make the evening feel like logistics rather than Halloween.
Who should go: Adults and older teens looking for a serious haunted-house night in Seattle itself.
Before you buy: Use the Morgue’s current calendar for the date, admission, and any rules that apply to your group.
BOO Seattle: Halloween weekend for dance music fans
For electronic music, BOO Seattle is one of the month’s biggest plans. The 2026 festival is set for Friday, October 30, and Saturday, October 31, at WaMu Theater near Lumen Field. The organizer’s hours and information page lists 5 p.m. to 1:30 a.m. for each event night. Be careful on that page: it also contains older 2025 box-office text, so rely on the entries specifically marked 2026 and check again close to the show.
BOO is where Halloween costumes meet a large-scale rave. Insomniac describes the Seattle edition as a multi-stage festival spanning sounds such as house, trap, and dubstep. RMR covered its early Seattle years in a BOO Halloween recap, so this is a natural event for us to revisit with current reporting, artist interviews, and a fresh look at the crowd. The official 2026 lineup page should be your source for set decisions; don’t plan around a past year’s poster.
BOO requires some planning beyond choosing a costume. The ticket page states that attendees must be 18 or older; VIP areas require guests to be 21 or older. Compare a single-night ticket with the two-day options if you have specific artists to see on both dates. WaMu’s stadium-district location also makes transit or a planned rideshare pickup worth considering, particularly when everyone leaves at once.
Who should go: Fans who want the music to be the main event, with Halloween production built around it.
Before you buy: Check the daily lineup, age rules, ticket tier, and the latest entry information.
Gorillaz at Climate Pledge Arena on Halloween night
Seattle has a particularly good concert competing for October 31 this year. Gorillaz play Climate Pledge Arena on Saturday, October 31, 2026, with the show listed for 7:30 p.m. and doors at 6:30 p.m. The date alone makes it a Halloween plan, and Gorillaz’s visual world gives it a better fit for the night than most arena concerts would have.
This is the pick if your group values an actual concert over a themed party. Make the show the center of the evening, get food near Seattle Center beforehand, and resist buying a second timed ticket on the other side of town. The venue’s event page has the current ticket link and door time.
There’s a useful October 31 choice here: Gorillaz for a concert, BOO for a festival, or Seduction for a costume-focused party. They’re different nights even though they share the same date. Choose based on what you want to spend your money and hours doing, not on which flyer looks most Halloween-themed.
Who should go: Music fans who want Halloween night anchored by a major live performance.
Nile Nightmares in Mountlake Terrace
Nile Nightmares is one of the better options north of Seattle. It operates at the Nile Shrine Golf Course in Mountlake Terrace, where the organizer lists free onsite parking. Its posted 2026 schedule includes Fridays and Saturdays from October 2 through October 31, 7 to 11 p.m., the final three Sundays in October from 7 to 10 p.m., and Thursday, October 29, from 7 to 10 p.m.
That range of dates makes it easier to fit into October than a one-weekend event. You can keep Halloween night available for a concert or party and do your haunted-house outing earlier in the month. If you’re in Shoreline, Edmonds, Lynnwood, or elsewhere north of the city, the location may also make more sense than driving down to Georgetown and back.
Nile has a separate daytime option for kids: its Family Funfest on Saturday, October 17, from 11 a.m. to 3 p.m. The organizer says children can walk through the attraction with the lights on and no live actors, collect candy, and take part in other activities. That is a materially different experience from its nighttime haunt, so make sure you buy for the one your group actually wants. Admission information for the family event was still marked pending on the organizer’s page when we checked.
Who should go: Haunt fans north of Seattle, or families seeking the specifically advertised daytime Funfest.
Wild Waves Fright Fest: One final October in Federal Way
This year’s Wild Waves Fright Fest carries a little extra weight for people who grew up in Western Washington. The Federal Way park says 2026 is its final operating season, with Fright Fest leading up to its planned November 1 closing. Its event calendar lists Fright Fest on Fridays, Saturdays, and Sundays from October 2 through November 1, with haunted houses, scare zones, entertainment, and nighttime rides.
That makes this more than an interchangeable haunt recommendation. If Wild Waves was part of your summers as a kid, October is a chance to walk the park again before it closes. The water-park season is over; this is a fall visit for the theme park and Halloween programming. Check the park’s Fright Fest information for the day you want, since hours and attraction availability matter more than the overall season dates.
Families should look at Booville, Wild Waves’ separate, less scary daytime Halloween zone. The park lists Booville on Saturdays and Sundays from September 26 through November 1, with trick-or-treating and family activities. The organizer says Booville closes at 6 p.m., so it should not be treated as a nighttime alternative to Fright Fest.
Who should go: People who want one last visit to Wild Waves, plus groups looking for a park-scale Halloween outing south of Seattle.
Maris Farms Haunted Woods in Buckley
If a dark trail through actual corn and woods sounds scarier than a warehouse full of props, drive to Maris Farms Haunted Woods in Buckley. The farm describes a roughly 35-minute walk through corn, constructed sets, a vortex tunnel, and wooded sections. It recommends the haunt for ages 12 and older and says the experience runs for just 14 nights in 2026, beginning September 26 and ending October 31.
A farm haunt asks something different of you than a city attraction. Wear shoes suited to an outdoor walk, dress for an October night, and give the drive its own evening. Maris says Haunted Woods admission is separate from its regular fall-festival ticket. Its dates and pricing page currently lists Haunted Woods tickets starting at $45, but your actual price depends on the date and ticket choice. Parking is listed as free.
You can also build a longer farm visit around it. The organizer says Haunted Woods ticket holders may arrive up to two hours ahead of their haunt time to enjoy parts of the farm, while certain activities require an additional option. Read the ticket inclusions rather than assuming every daytime attraction carries into the evening.
Who should go: Groups that want an outdoor haunt worth a dedicated trip, especially those willing to trade city convenience for a darker setting.
Grand Illusion’s All Monsters Attack! series
Seattle’s horror movie calendar deserves as much attention as its haunted houses. Grand Illusion Cinema’s All Monsters Attack! 2026 series begins at the SIFF Film Center on October 3 with From Beyond and Society. The program continues across the month with screenings including Session 9, Videodrome, I Walked with a Zombie, the documentary Black Zombie, and a television horror triple-feature pizza party. The organizer provides a ticket link and venue for each film; use the individual screening rather than assuming the whole series plays at one time or location.
For RMR, the standout is October 4’s Session 9 screening, which Grand Illusion lists with an introduction and Q&A featuring local experimental musicians Climax Golden Twins, composers of the film’s score. That is the sort of Seattle-specific intersection of music and horror that a national Halloween list would probably miss. On October 17, the pairing of I Walked with a Zombie and Black Zombie offers another reason to spend an evening at the theater: the two works put horror history and the origins of the zombie image in conversation.
Film programming gives you flexibility. A screening can be the entire plan, or it can start an evening before dinner and drinks. It’s also a better use of a weeknight than trying to drive out to a large haunted attraction after work.
Who should go: Horror fans who want a curated program and the experience of watching these films with an audience.
MOPOP’s horror exhibit
The Museum of Pop Culture’s Scared to Death: The Thrill of Horror Film gives Seattle Center another October stop. MOPOP describes a collection with more than 50 props and costumes spanning horror cinema. If the craft of horror interests you as much as the finished movie, a daytime visit here pairs well with a film screening or a Seattle Center concert later on.
A factual note matters: an old MOPOP Halloween party page called “Fashionably Undead: The Goopening” still appears prominently in search, but its event date is October 25, 2025. It should not be promoted as a confirmed 2026 party. The horror exhibit is the current recommendation; watch MOPOP’s events calendar if you want to see whether the museum announces new October programming.
Who should go: Horror-film and pop-culture fans who want something they can do during the day.
Seduction at Seattle Center
For adults looking for a Halloween costume party rather than a haunt or concert, Seduction: Wicked Wonderland is scheduled for Saturday, October 31 at the Seattle Center Exhibition Hall. Seattle Center lists an 8 p.m. start and identifies the event as a fundraiser for the 2027 Seattle Erotic Art Festival. The organizer advertises music, dancing, performances, and a costume contest.
This is an adults’ night with its own tone and audience. Read the organizer’s event and ticket information before choosing a costume or inviting friends. If you are already planning to spend Halloween near Seattle Center, it competes directly with Gorillaz for the evening rather than serving as a casual stop you can count on fitting in afterward.
Who should go: Adults who want costumes, dancing, and a party with a defined theme.
This Is Halloween at The Triple Door
Can Can’s This Is Halloween runs at The Triple Door from October 15 through October 31. The production brings together live music, cabaret, burlesque, and theatrical visuals. Tickets are currently listed from $35 to $75, with age guidance that varies by performance: the ticket page marks 9 p.m. shows as 21+ and Sunday 5 p.m. performances as all ages, while warning that all-ages performances still contain PG-13 material.
This is a good middle ground for a group that wants to dress up and see a show but doesn’t want to spend the night walking through a haunt. The downtown location also makes dinner planning relatively straightforward. Pick a specific performance first, then check its doors and age restrictions; the show’s overall October run does not mean the same schedule applies every day.
Who should go: Fans of theatrical Halloween nights, cabaret, and live performance.
Woodland Park Zoo’s Pumpkin Bash
On Halloween day, Woodland Park Zoo’s Pumpkin Bash is scheduled for 9:30 a.m. to 3 p.m. The zoo lists trick-or-treating, costumes, activities, and pumpkins given to animals as enrichment. Activities are included with zoo admission or membership. The organizer says one child age 12 or under receives free admission with each full-priced adult ticket during Pumpkin Bash; read the offer before buying tickets for your group.
The appeal goes beyond getting kids into costumes. Watching an animal investigate, smash, or eat a pumpkin is genuinely fun, and the daytime schedule leaves Halloween night open for neighborhood trick-or-treating. If you are taking younger children, this is one of the clearest choices in the guide because the programming was built for them rather than adapted from an adult event.
The zoo also has an Animal Ofrenda on its fall calendar in connection with Día de Muertos. Treat that as its own remembrance activity, with meaning beyond Halloween decoration.
Who should go: Families looking for a daytime Halloween plan within Seattle.
Día de Muertos Festival Seattle
Seattle Center’s Día de Muertos Festival Seattle is scheduled for October 31 and November 1 in the Armory Food & Event Hall. It is part of Seattle Center Festál, whose cultural festivals are free to attend. The event offers another way to spend time at Seattle Center across Halloween weekend, with art and community at its center.
Día de Muertos is a tradition of honoring and remembering loved ones. It belongs on an end-of-October calendar, but it should not be described as a Halloween party or haunted attraction. Follow the festival’s official page for its program and daily hours as they are posted, and go with the intention of experiencing the celebration respectfully.
Who should go: Anyone interested in art, cultural celebration, and a free Seattle Center event over the weekend.
Which Seattle Halloween plan should you pick?
If you want a haunted house in Seattle, book the Georgetown Morgue. If you live north of town, compare it with Nile Nightmares before committing to the drive. For a larger outdoor scare, Maris Farms makes a strong case for an entire evening in Buckley.
For music, BOO Seattle takes the festival slot and Gorillaz takes the concert slot. Both are major Halloween-weekend commitments. If you would rather wear a costume and dance at a themed party, look at Seduction. If you want performance without a late-night festival crowd, This Is Halloween gives you multiple dates at The Triple Door.
For families, start with Woodland Park Zoo’s Pumpkin Bash, Nile Nightmares’ specifically designated Family Funfest, or Wild Waves’ daytime Booville. Fright Fest and Haunted Woods are different experiences with different scare levels. Wild Waves also carries the added significance of being the park’s final Halloween season.
One last Seattle-specific suggestion: spread your plans across October.
Take a weeknight horror screening, do one haunt on a Friday, and save Halloween night for the concert, festival, party, or neighborhood gathering you care about most. That gives each event room to be good on its own terms. RMR’s Halloween music guide can handle the soundtrack on the way there; the choice of where to go is yours.
