Illustration of a generic family scene (Boo Bash!)

Boo Bash!

Visitors can join a costume parade, hunt for fossils and gems at the haunted sluice, and hammer golf tees into pumpkins. Families can launch a ghostly ghoul through the Airway Maze, make ghoulish graffiti on the chalk wall, and capture a keepsake photo. Select days also offer wacky science demonstrations, cider pressing, live bug specimens with cricket tasting, and silkscreening glow-in-the-dark boo bags.
