Howl-O-Scream has transformed the peaceful SeaWorld into something sinister this Halloween. Nightfall awakens hundreds of creatures roaming scare zones and lurking the halls of haunted houses.

Back for the 20th year, Howl-O-Scream returns with scarier experiences including the all-new horror-filled haunt, The Swamp at Blackwater Bayou and three new terror-tories.

Visitors can visit one of the signature Halloween bars, ride coasters at night, and close the night with live entertainment by some favorite creepy creatures and monsters.
