Fun & Safe
Trick-or-Treating
Come in costume and follow the BOO Trail trick-or-treating stations throughout the park. This is a FREE, safe, & family-friendly experience for all ages to collect candy throughout Boo Alley!
Either a single-day admission ticket or valid 2025 or 2026 Premium Membership is required for admission to The Great Big BOO!
The Great Big BOO runs from September 26 through November 2. The park will be closed due to a private event on October 11.
The Great Big BOO!
“Do the BOO” at the live musical show that started it all! You’ll meet a charming cast of characters including Vinnie the Vampire and Frankie the Lounge Singer in a wacky adventure to save Halloween from the curse of Wendella the Witch.
Tricks & Treats on the BOO Trail
Come in costume and follow the BOO Trail throughout the park to go trick-or-treating for candy.

The Great Big BOO offers delicious delights for all ages—like loaded jumbo potatoes, apple pumpkin funnel cake, and kid-friendly drinks with a magical twist.
