Ocean Park Hong Kong is bringing more than their usual rollercoasters this fall, unveiling their most ambitious Halloween Fest yet, complete with an original haunted realm co-created by global icon Jackson Wang.

The 2026 edition of the park's "The Grave Rave"-themed Halloween Fest runs from Sept. 5 to Nov. 1, 2026 on designated dates, marking one of Hong Kong's largest seasonal takeovers, with new haunted zones, roaming ghouls, gothic dance parties, and a nightlife-style finale.

Headlining the event is the "FWD Insurance Presents: Under the Castle Haunted Experience," based on "Under the Castle," an original fantasy universe created and creatively directed by Jackson Wang. The attraction reimagines The Summit as a mist-covered, neon-green castle where guests wander through mirror illusions and escape crystal-cursed "living dead" creating a looping nightmare that blur reality and dream.

The Under the Castle zone extends well beyond the haunted house. A dark ride, "Bumper Blaster," bathes its bumper cars in shadowy green light as riders dodge roaming ghosts, while a carnival-style "Nightmare Game Booth" offers limited-edition prizes. Guests can also stop by the "SnapGenie Spot," an interactive booth generating AI-powered fantasy photo backdrops; "Into the Mirror," a gravity-defying photo installation built for social media; and the "Phantom Lounge," a nightly ballroom dance where a mysterious host presides over a classical waltz. A separate "Gothic Ball" invites gothic-attired guests to sway to distorted classical music in a darkly romantic hall.

Three more haunted zones round out the scare lineup: "AEON Card Presents: Voodoo Boo Terror Park," a 3D-glasses blackout experience at The Waterfront that plunges guests into a distorted spectral world and challenges them to restore the park's power; "Orion Beer Presents: Troublesome Night 8," inspired by the classic Hong Kong horror film of the same name, which winds through abandoned villages and coffin altars under a mysterious medium's guidance; and "Forbidden Asylum," where guests use bone-conduction headphones to investigate a psychiatric hospital's mass disappearance and uncover a "bloody truth." A parallel dimension, "Hong Kong Paranormal Barrier," resurrects local legends, including paper dolls, Meng Po, a Taoist priest, and the Black and White Impermanence.

Voodoo Boo, the mischievous ghost anchoring the Waterfront zone, also returns for meet-and-greet sessions and a game party, "Voodoo Boo All Night," featuring hosts, games, and hidden prizes.

For scares, you can pose with roving costumed characters and Ocean Park has doubled the number to more than 120 characters spread throughout the park.

Nightly entertainment includes "Trip.com Presents: OPPA Scaremonies," featuring an eight-member "infernal" group called Demoon King, and Hong Kong's largest-ever "Ghoulish Cosplay Party," complete with an OOTD contest crowning a Ghost King and Queen, solo character showcases and DJ sets spanning Canto-Pop, J-Pop, and K-Pop. A few more shows round out the lineup: "Sway Pole Spectacle," with stilt performers; "Diva Paper Doll Reviving Night," in which joss paper dolls come to life; "Fright Spark Sliders," featuring acrobatic zombies; "Asylum Forbidden Stage," a high-energy dance showcase from "asylum inmates;" Skelebration Fiesta," a daytime celebration that turns into a skeleton parade after dark; and lastly, a roaming "Spooky Live Band."

Families have plenty to look forward to. The "Bulu Boo Trick-or-Treat Party" and "Trick or Roll Game" offer lower-scare, candy-focused joy for kids, while a haunted ride on the Ocean Express and the nightly light-and-water show "Gala of Lights: Let in the Dark," featuring projections, water curtains, and dancing fountains.

Entry to the designated haunted houses and select attractions requires a Halloween Haunted Combo Ticket, and event details are subject to change without prior notice.
