Howl-O-Scream


Howl-O-Scream is Back for another Terrifying Year


Howl-O-Scream has transformed the peaceful park you once knew into something sinister this Halloween. Nightfall has awakened hundreds of creatures roaming Terror-tories and lurking the halls of haunted houses. SeaWorld's Howl-O-Scream includes FREE haunted houses that are included with your park admission.


Back to fuel your nightmares, Howl-O-Scream returns with scarier experiences including TWO new horror-filled haunts (six total) and EIGHT Terror-tories!


Replenish your thirst for terror at one of our signature Howl-O-Scream bars. Find ultimate thrills, as you ride coasters at night. Close the night with live entertainment by some of your favorite creepy creatures and monsters. Thrills and chills await you this September and October at Howl-O-Scream, the BIGGEST and SCAREIST Halloween event in Texas!
