What Is Fright Fest?
Fright Fest is Six Flags Great America’s annual Halloween event, running on select days from mid-September through early November. The tagline says it best: thrills by day, frights by night. During daytime hours, the park feels mostly like its normal self with some Halloween decor mixed in. You’ll find family-friendly trick-or-treating and a kids’ Boo Fest with character meet-and-greets and a costume contest.
Once the clock hits 6pm, everything changes. Scare zones activate throughout the park, haunted houses open their doors, and roaming monsters take over the midways. The park leans hard into its “no mercy after 6pm” promise, and it delivers.
The event has been running for decades and continues to evolve each year with new haunted house themes, scare zones, and shows, while keeping the core formula that’s made it a Chicago-area Halloween staple.
Daytime vs. Nighttime: Know Before You Go
This is the most important thing to understand about Fright Fest, because the two halves of the day are genuinely different experiences.
During the day, the park is family-friendly. Regular rides are running, decorations are up throughout the park, and younger kids can enjoy trick-or-treating and the Boo Fest activities without encountering anything too intense.
After dark, things shift quickly. Scare zones fill with actors in full makeup and costume, haunted houses open, and select coasters run in the dark for an extra layer of intensity. Six Flags recommends the nighttime scares for guests 13 and older. Costumes generally aren’t allowed for anyone over 12 once scare zones are active, which helps actors and guests tell each other apart. The park typically doesn’t allow re-entry after a certain time in the evening, so plan to either commit to the night or head out before it ramps up.
If you’re bringing younger children, our suggestion is to plan your visit around the daytime hours and Boo Fest, then head out as dusk approaches. If you’re going for the scares, arrive in the late afternoon so you get a feel for the park in daylight before everything changes.
Haunted Houses
The haunted houses are the centerpiece of Fright Fest’s nighttime lineup, and they require either a Haunted Attractions Pass or a bundled ticket that includes both park admission and haunted house access (these are not included with regular admission).
Past and recent lineups have featured houses themed around major horror franchises, including mazes inspired by The Conjuring Universe, SAW, and Texas Chainsaw Massacre. You’ll also find original concepts like Big Top Terror, a twisted circus walkthrough in the County Fair area, alongside other rotating themes. The exact lineup changes from year to year, with new houses added regularly, so part of the fun is seeing what’s new each season. If you’re a haunted house enthusiast, check the current year’s lineup before you go, since the franchise tie-ins tend to draw the longest lines.
Scare Zones
Scattered throughout the park after dark, scare zones are outdoor areas transformed with fog, lighting, themed decor, and actors who roam and interact with guests. Unlike the haunted houses, scare zones are included with general admission, so even if you don’t spring for the Haunted Attractions Pass, you’ll still get plenty of atmosphere and jump scares just walking between rides.
The number and themes of scare zones change year to year, with the park regularly adding new ones alongside long-running favorites.
Live Shows
Fright Fest also features live entertainment that’s worth building your evening around. Two of the most enduring shows are:
Love at First Fright – A long-running stage show, performed at the Grand Music Hall, featuring music, singing, and dancing built around a cemetery-set storyline. It’s been a Fright Fest staple for decades and gets fresh touches each year while keeping its core charm.
The Ringmaster’s Cabaret – A circus-themed show combining illusions, music, and performers leaning into the freakish, carnival side of Halloween, also at the Grand Music Hall.
Showtimes vary throughout the season and by day of the week, so check the park’s daily entertainment schedule once you arrive to plan your evening around them.
Rides After Dark
One of the most underrated parts of Fright Fest is simply riding the park’s coasters after the sun goes down. Riding in the dark changes the experience of even familiar rides, and with cooler fall temperatures, lines tend to move faster than they do during peak summer crowds. If you’re a coaster enthusiast, a Fright Fest evening can actually be one of the best times of year to get more rides in.
Tips for Visiting Fright Fest
A few things we’ve learned from going year after year.
Check the calendar first
Fright Fest runs on select days, not every day of the week. Confirm the schedule for your visit date on the official Six Flags site before you plan around it.
Arrive in the late afternoon
This lets you enjoy some daytime hours, grab dinner, and be in position as scare zones and haunted houses open for the night.
Dress for the weather, not just the scares
September and October evenings in northern Illinois can get cold fast once the sun goes down. Layers are your friend.
Decide your scare tolerance ahead of time
If haunted houses aren’t your thing, scare zones, shows, and rides are all included with regular admission and can still make for a great night.
Go on a weeknight if you can
Weekend nights get significantly busier, especially close to Halloween. A less busy night means shorter lines for both rides and haunted houses.
Consider a season pass if you’re local
If you’re within driving distance and might visit more than once during the regular season and Fright Fest, a season pass often pays for itself. It also gives you the flexibility to do a shorter visit without feeling like you need to “do everything.”
Fright Fest FAQ
Is Fright Fest scary for young kids?
The daytime portion is family-friendly, with regular rides, decorations, and the kid-focused Boo Fest including trick-or-treating, character meet-and-greets, and a costume contest. Once scare zones and haunted houses open in the evening, the experience shifts toward older kids, teens, and adults. If you’re visiting with young children, plan to enjoy the daytime hours and head out before dusk.
What age do you need to be for the nighttime scares?
Six Flags recommends the nighttime scare zones and haunted houses for guests 13 and older. Costumes are generally not allowed for anyone over 12 once the scare zones are active, since it helps actors and staff distinguish guests from performers.
Are the haunted houses included with park admission?
No. Scare zones, shows, and most rides come with regular admission. The haunted houses need a separate Haunted Attractions Pass or a bundled ticket that includes both park admission and haunted house access.
When does Fright Fest start and end each year?
Fright Fest typically runs on select days from mid-September through early November, with the heaviest schedule on weekends as Halloween approaches. Exact dates and operating days vary by year, so always check the current schedule on the official Six Flags Great America site before planning your visit.
Is Fright Fest included with a season pass?
Yes, Fright Fest is included with Six Flags Great America season passes and memberships at no extra cost for park admission. Haunted houses still require the separate Haunted Attractions Pass regardless of pass type.
What should I wear or bring to Fright Fest?
Layers are key. Fall evenings in northern Illinois cool down quickly after sunset, even if the afternoon is warm. Comfortable shoes for walking, a light jacket, and a portable phone charger (for photos and navigating the app) are all worth having.
Is Fright Fest Worth It?
After many visits over the years, our answer is an easy yes. Fright Fest takes a park we already love and gives it a completely different personality for a few weeks each fall. The combination of haunted houses, scare zones, shows, and rides in the dark works for almost any group, whether you’re bringing young kids for daytime trick-or-treating or going all-in on the scares after dark.
