Enchanted Parks ran Halloween at six parks in fall 2026, from ValleyScare at Valleyfair to Diggerfest at Diggerland USA, which runs weekends through November 15, and four of them paired a family event by day with a haunt after dark. It was the chain’s first Halloween at the four parks it took over from Six Flags in April, and every family event added allergy-safe trick-or-treat stops through FARE’s Teal Pumpkin Project.

How the Day and Night Split Worked
- Valleyfair: ValleyScare was a separate ticket in 2026, $49.99 online with all five haunted mazes included, and a combo ticket for the day and night was $74.99. On Saturdays, everyone left at 5:30 p.m. when Tricks and Treats closed, and ValleyScare ticket holders came back in through the Steel Venom gates.
- Worlds of Fun: one Halloween Haunt ticket, $44.99 online on October 8, covered the rides, daytime Tricks and Treats, and all six haunted mazes after dark. There was no Tricks and Treats on Fridays.
- Mid America Adventure: Fright Fest came with park admission, and a daily ticket was $40.99 online on October 8. The four haunted houses needed a Haunted Attractions Pass, from $27.99. Both Missouri parks are in my Missouri haunted houses guide.
- Great Escape: Boo Fest started at noon and Fright Fest at 5 p.m., both with park admission. The four haunted houses needed a separate wristband or maze pass.
The 2026 chaperone rules by park:
- ValleyScare: guests 17 and younger needed a chaperone who was at least 21.
- Worlds of Fun: the same rule applied from open to close on every Halloween Haunt day.
- Mid America Adventure: guests 16 and younger needed a 21-plus chaperone for the haunted attractions.
Mall of America ran the same day and night split indoors in 2026: the operator of the Twin Cities Fear Fest haunted house also sold Magic of Halloween, a $10 walk with no scares, with entries from 3 p.m. to 6:15 p.m., and the haunted house ran at night at the same address.
The Haunts
- ValleyScare at Valleyfair: five haunted mazes, four scare zones, six shows, and a new interactive lantern that sets off fog, lights, and sounds around the park. Full details are in my ValleyScare 2026 guide.
- Halloween Haunt at Worlds of Fun: six haunted mazes, four scare zones (three of them new), and five shows, including the new Spellbound. See my Worlds of Fun Halloween Haunt 2026 guide.
- Fright Fest at Mid America Adventure: four haunted houses, including the new Gordy’s Gruesome Revenge, seven scare zones, and the last season of the show Love at First Fright, which ended after 32 seasons. See my Mid America Adventure Fright Fest lineup.
- Fright Fest at Great Escape: four haunted houses (Nightmare, Skull Manor, CarnEVIL, and Hell Block VI), three scare zones (Dead in the West, Dark Oaks Graveyard, and Sirens), and three new shows: PigFace, Grunge Monsters, and Weird Tales Story Hour. Great Escape is in my Fright Fest guide to every park.
The Family Events
- Tricks and Treats at Valleyfair and Worlds of Fun: Saturdays and Sundays, with trick-or-treating and kid-friendly shows.
- Boo Fest at Mid America Adventure: Saturdays and Sundays through November 1, with four new experiences: Kid’s Mash Bash, Gordy’s Candy Trail, McBoogle’s Pathway, and Spooky Stories with Jack.
- Boo Fest at Great Escape: weekends from noon, with trick-or-treating at the Storytown houses in Buckaroo Junction, a Monster Mash dance party with Count Dracula, a hay maze, and a costume contest for kids 12 and under. The Great Escape Lodge, with its indoor waterpark, also ran a Boo Fest each weekend through October 31.
- Diggerfest at Diggerland USA: weekends through November 15, with trick-or-treating, hayrides, and a Parade of Machines. More in my Diggerfest story.
- Autumn Adventure at Water Safari: select Saturdays, September 19 through October 24, with trick-or-treating on Storybook Lane, the Haunted Train, a costume contest, and the new Paul Bunyan’s Log Haul ride. Tickets were $15 per person, sold online only.
Allergy-Safe Trick-or-Treating
Enchanted Parks joined FARE’s Teal Pumpkin Project in 2026, with non-food trick-or-treat stops at all of its family-focused Halloween events. The project, from the nonprofit Food Allergy Research & Education, encourages hosts to offer non-food treats for kids with food allergies.
“We understand some families don’t feel comfortable taking part in some Halloween-themed activities because the risk of being exposed to an allergen is too high for their children,” said James Harhi, chief executive officer of Enchanted Parks. “When families come out to our events, we want everyone to be able to take part and have a great time.”
Deals and Passes
Worlds of Fun and Mid America Adventure both sold two tickets for the price of one through October 4, for use by October 11. At every park, a 2027 season pass included the rest of 2026, Halloween events included. I add each park’s 2027 Halloween dates here as they are posted.
