Revised October 11, 2026
What Halloween events happen in St. Louis every year?
For scares: The Darkness, Creepyworld and the Lemp Haunted House, plus Fright Fest at Mid America Adventure in Eureka. For families: Boo at the Zoo, Halloween Nights at Grant’s Farm and Pirates and Pumpkins at the St. Louis Aquarium in Union Station. For pumpkins: Eckert’s in Belleville, Thies Farm’s Pumpkinland and Stuckmeyer’s. Most run late September through Halloween weekend.

That’s Halloween in St. Louis. Here, trick-or-treaters tell a joke before they get the candy, a habit that goes back to just after World War II and still baffles every transplant on the block. Teenagers do it too, usually with the worst pun they can find. New in town? Have the kids practice one before the 31st, because a St. Louis porch expects it.
The rest of October piles on around it: screams leaking out of The Darkness onto the sidewalk near Soulard, a haunted hayride rattling through the dark at Creepyworld in Fenton, the glow of Jack’s Lighted Trail at Eckert’s in Belleville while your breath fogs and your kid clutches a pumpkin bigger than their head.
Pick by the most nervous person in the car.
Wants to be genuinely scared? Strobe light, a scream right behind you, a hand on your shoulder that isn’t your friend’s. That’s The Darkness, at 1525 South 8th Street next to Soulard Market, or Creepyworld’s scream park at 1400 South Old Highway 141 in Fenton. One combo pass covers both. Everyone walks through a metal detector, and ticket sales are final, no refunds. Both go from weekends in late September to nightly as Halloween gets close, and the last two weekends sell out, so buy timed tickets ahead or go on a weeknight.
Is five years old? Glow sticks bobbing through Forest Park after dark: Boo at the Zoo, select October nights from 5 to 8:30 p.m. (last entry at 8). It’s $16 this season, $13 for members and free under age 2, parking in the park is free, scary costumes stay home, and there’s a sensory-friendly night with quiet areas and sensory maps. The insider catch: on Boo nights the zoo clears everyone out at 4 p.m. and reopens at 5, so a daytime zoo visit can’t just roll into the party.
Just wants a pumpkin and something warm? Mud on your boots and a hay wagon bumping out to the field: Eckert’s in Belleville, about 25 minutes east of downtown, or Thies Farm’s Pumpkinland, Stuckmeyer’s in Fenton and Rombachs in Chesterfield, generally late September through October 31. Go early on a weekend, before the best pumpkins are picked over.
Before you plan around an old list, four things have changed. Union Station’s Trick or Train isn’t on the calendar anymore; the St. Louis Aquarium’s Pirates and Pumpkins, with underwater pumpkin carving, runs there from mid-September into November 1 instead. Six Flags St. Louis is now Mid America Adventure, and Fright Fest still takes over the park after dark. Purina Farms’ kids’ Halloween event is on hold while tornado damage keeps its visitor center closed. And St. Charles turns Main Street into Legends & Lanterns on October weekends, free.
The whole season at a glance, scary to not-scary
Here’s a Saturday in late October. The line outside The Darkness stretches down the sidewalk near Soulard, fog rolling out every time the doors open. Out in Fenton, Creepyworld’s hayride wagons rumble past in the dark to a soundtrack of screams. And in Forest Park the zoo’s lights come up at 5 for a crowd of very small superheroes. Most of it runs from late September through late October or early November.
For the fearless: haunted houses and scream parks
You hear the flagship before you see it: screams leaking out the doors and a line of people laughing a little too loudly to prove they aren’t nervous. Then you’re in the first black corridor, hand on the shoulder in front of you, fog thick enough to taste. The Darkness, in the Soulard area near Ballpark Village, has been terrifying visitors for more than three decades, and it has been featured on the History Channel’s Modern Marvels and on the Travel Channel. Haunt owners in town for the industry’s Transworld trade show have toured it to see how it’s done. A short distance away, the same company’s Lemp Haunted House on Lemp Avenue leans into the neighborhood’s real haunted lore for a second, distinct scare.
Need something to wear first? Here’s how to choose a Halloween costume.
For a bigger, outdoor-heavy experience, Creepyworld in Fenton (off Highway 141) is a sprawling “scream park” with multiple attractions including a haunted hayride - a full night out rather than a single walk-through. And for scares wrapped inside a theme park, Fright Fest at Mid America Adventure (the former Six Flags St. Louis) in Eureka overlays the whole park with haunted mazes and scare zones after dark while the coasters keep running. These ramp up from weekend nights in late September to nightly as Halloween approaches, so buy timed tickets ahead and expect lines on the closest weekends.
For families: not-scary Halloween fun
Plenty of the best local Halloween is built for little ones: tiny bumblebees and dinosaurs waving glow sticks, costumes encouraged, scares dialed all the way down. The classic is Boo at the Zoo, the Saint Louis Zoo’s after-hours family event in Forest Park, where costumed kids ride the Emerson Zooline Railroad in the dark and the Primate House stays open after sunset. It’s a themed evening rather than a trick-or-treat event, scary costumes stay home, and guests 14 and older can’t wear full-face masks or face-covering makeup. It runs select evenings through most of October and is a beloved rite of the season for St. Louis families.
Halloween Nights at Grant’s Farm in Grantwood Village is another family favorite - an after-dark experience with a haunted tram ride (watch for the headless horseman), decor, and shows, plus a daytime Fall Fest at the Clydesdale stables for the younger set. Downtown at St. Louis Union Station, the St. Louis Aquarium’s Pirates and Pumpkins season runs from mid-September into the first day of November, with underwater pumpkin carving plus a Trick or Treat Night and a Trick, Treat & Toast evening on the aquarium’s calendar. Purina Farms in Gray Summit used to run a not-so-scary kids’ Halloween event, but its visitor center has been closed since the March 2025 tornadoes, so check the farm’s own site before you plan around it.
For the harvest crowd: pumpkin patches and farms
Some of the most reliable fall fun around St. Louis skips the scares completely: hayrides, corn mazes, and the annual hunt for the perfect pumpkin. The regional heavyweight is Eckert’s in Belleville, Illinois (about 25 minutes east of downtown), an eighth-generation family farm with pick-your-own pumpkins and “Ecktoberfest” festival weekends; its newer Jack’s Lighted Trail, a walkable illuminated pumpkin path, has become a fresh evening draw.
On the Missouri side, Thies Farm & Market’s Pumpkinland brings a straw castle, corn maze, and rides; Stuckmeyer’s Farm in Fenton (near the junction of Highways 141 and 21) runs Saturday “Halloween Family Fun Days” with farm animals and hayrides; and Rombachs Farm in Chesterfield opens daily in October with its “Great Pumpkin Pyramid.” These are the low-key, daytime, all-ages side of the season - perfect for younger kids, photos, and a wagon full of pumpkins - and they generally run from late September through October 31.
Random, but: every O’Fallon business worth knowing is one click away.
The St. Louis Halloween calendar, week by week
It starts with fog machines in Soulard and ends with kids counting candy on the living-room floor. The exact dates slide a little each year, but the rhythm holds. Mid-to-late September: The Darkness opens, Creepyworld kicks off with a late-September “Slasher Weekend,” and the aquarium’s Pirates and Pumpkins season starts at Union Station. Late September into October 1: the farms open their pumpkin fields and corn mazes, and Stuckmeyer’s Saturday fun days get rolling. The first full weekends of October: Boo at the Zoo opens for select nights, Grant’s Farm’s Halloween Nights are in full swing, and St. Charles turns historic Main Street over to Legends & Lanterns, a free festival of storybook villains, ghost stories and a Day of the Dead plaza that runs on October weekends. The last two weekends: everything is open at once, the haunts go nightly, and the best tickets sell out. Halloween and just after: trick-or-treat hours are set town by town, and the St. Louis rule still holds on every porch: tell a joke, get the candy, a habit that goes back to just after World War II. Fright Fest at Mid America Adventure runs through the first day of November.

Trick-or-treating and neighborhood happenings
Beyond the ticketed attractions, the oldest Halloween tradition of all is still going strong across the metro: door-to-door trick-or-treating. One thing that surprises newcomers - there’s a local wrinkle to it. In much of the St. Louis area, kids are expected to tell a joke before they get their candy, a “St. Louis trick” that generations here grew up with and that puzzles visitors from anywhere else. It’s a small, charming piece of local culture worth knowing before your first Halloween in town.
Because trick-or-treat night and its hours are set locally, they vary by municipality - each city and suburb tends to announce its official window, so check your city’s page or social media as the date nears. Many neighborhoods, churches, and business districts also host trunk-or-treats and fall festivals - safer, contained, weather-friendly alternatives that are great for younger kids - and shopping centers and malls sometimes run daytime candy events. A quick local search in the days before Halloween usually turns up several within a short drive.
For the grown-ups, the season has its own nightlife: costume parties and Halloween-themed events pop up at bars, breweries, and event spaces across the city and suburbs in the days around the holiday, and the metro’s genuine haunted-history spots lean into the season with tours and special evenings - a seasonal turn on the unique, offbeat St. Louis outings adults seek out year-round. Between the daytime family traditions and the after-dark options, the only real question left is how spooky you want to get.
What to expect at a haunt (and how to survive it)
If you’re new to the big haunted attractions, a little know-how makes the night better. The premium haunts are a real production: expect elaborate, multi-room sets, live actors whose whole job is to make you jump, plenty of fog, strobe effects, and loud sound design. They’re intense by design - genuinely too scary for young children, and worth being honest with yourself about if you spook easily. A scream park like Creepyworld bundles several attractions and a hayride into one ticket, so plan for a couple of hours on your feet, outdoors, in whatever the late-October weather is doing.
The practical playbook: buy timed tickets online in advance (the closest weekends to Halloween sell out and the lines are long), wear comfortable closed-toe shoes, dress for the actual temperature after dark, and go earlier in October or on a weeknight if you want smaller crowds. If you’re bringing a group with mixed nerves, know that most haunts don’t let you bail mid-attraction easily - so match the outing to the least brave person in your party, or split up and regroup after.
A morning at the pumpkin patch
The harvest farms deserve a little extra attention because they’re the most flexible, all-ages option of the season. A typical visit is a half-day out: a hayride to the pumpkin field, a corn maze to get lost in, a straw-bale playground or barnyard animals for the little kids, and cider, kettle corn, or apple-cider donuts on the way out. They’re built for photos - the wagons, the pumpkin pyramids, the fall color - and they’re a gentle, no-scares way to mark the season with toddlers and grandparents alike.
A few tips make the morning smoother: go early on weekends before the crowds and the best pumpkins thin out, bring cash for the stands that prefer it, dress the kids for mud after any recent rain, and check the farm’s page for whether admission, the maze, and hayrides are separate tickets or bundled. Weekdays, if you can swing them, are dramatically calmer than sunny Saturday afternoons.
How to plan your Halloween season
With this much on offer, a little planning goes a long way. Match the outing to your crew first: a genuine haunt like The Darkness or Creepyworld for teens and thrill-seekers, Boo at the Zoo or Grant’s Farm for families with young kids, and a pumpkin-patch morning at Eckert’s, Thies, Stuckmeyer’s, or Rombachs for the harvest crowd. Many families do one of each over the month - a patch early, a family night mid-month, and a scarier outing for the older kids as Halloween nears.
A few practical notes: the haunted attractions get busiest on the weekends closest to Halloween, so go early in October or on a weeknight if you can, and buy tickets in advance. The farms are weather-dependent and busiest on sunny weekend afternoons, so it pays to keep a few indoor St. Louis attractions built for a rainy day in your back pocket in case the forecast turns. And because exact dates, hours, and ticket prices change every year, always confirm on each venue’s official page before you head out - the events are annual, but the calendar isn’t identical two years running.
The range is what makes the metro so easy to plan around. Within a short drive you can go from a gentle pumpkin-patch morning to a genuinely terrifying scream park to a friendly night at the zoo, mixing and matching by the weekend. Book the haunts the day tickets go on sale - the weekends nearest Halloween are the first to sell out, and those are exactly the ones your teenagers will want.
