Howl-O-Scream, San Diego’s largest Halloween nighttime event, continues haunting during select nights through October 31 at SeaWorld San Diego. 2026 marks the event’s sixth year, with its largest lineup yet: six terrifying haunted houses. Guests will venture deeper into the darkness than ever before, confronting new scare zones, pulse-pounding live performances, dark speakeasies and themed bars, and unspeakable horrors lurking around every shadowed corner.
ALL-NEW Area 64: Mothership debuts as an all-new haunted house, designed and built entirely from the ground up by SeaWorld San Diego’s Entertainment team. Serving as the prequel to the fan-favorite Area 64: Alien Outbreak, the experience transports guests 30 years before the original story, where negotiations between a secretive government taskforce and an extraterrestrial species have spiraled into chaos. The attraction features an 80-foot-long, 16-foot-tall mothership façade — the largest show scene by volume ever created for a Howl-O-Scream San Diego haunted house.
ALL-NEW 6th House – a terrifying new haunted house will reveal itself from the murky depths of Mission Bay in a few short weeks.
RETURNING – Circus of the Damned 3D: an evil ringmaster unleashes chaos in a neon-lit, 3-D clown nightmare as he searches for new performers to restore his cursed circus.
RETURNING – Simon’s Slaughterhouse: Simon the Butcher delivers a gruesome walk through a deranged meat factory, dodging screeching buzz saws and meat hooks.
RETURNING – Deathwater Bayou: Awakening, where a Mardi Gras night in New Orleans takes a dark turn as witches summon an ancient, ravenous deity.
RETURNING – Nightmare Experiment: Sweet DreamzZz, guests are led through a converted asylum run by a mysterious pharmaceutical company testing a sleep aid with horrifying side effects.
Intended for a mature audience, Howl-O-Scream is a separately ticketed event. For more information and tickets, visit seaworld.com/san-diego/events/howl-o-scream/.
