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.


Boo Trail

Tricks & Treats on the BOO Trail

Come in costume and follow the BOO Trail throughout the park to go trick-or-treating for candy. 

Note: We encourage parents to dress up too but ask that all costumes remain family-friendly. Weapons and masks that cover the entire face are not allowed.

Downtown BOO Alley

The heart of BOO Alley is the bustling Halloween festival in the town center. See the pumpkin pyramid and make your way through the hay maze. You'll also find tasty BOO Alley treats, spooky drinks and fun souvenirs from festive vendor carts.
