The Nightmare Realm

One of Europe's biggest immersive horror attractions, The Nightmare Realm, is making its UK debut this Halloween season after 17 years of terrifying guests across the Irish Sea.
Their London debut will feature two brand-new headline experiences. Avery Hill Asylum, which invites guests inside a Victorian institution where the dangerously obsessive Dr Thorne has pushed medical experimentation beyond the limits of humanity, and Sundown Manor, which follows an ancient Irish bloodline that has crossed the Irish Sea in search of fresh victims.
Connecting both experiences is Halloween Town, an interactive village in which guests may overhear conversations, uncover hidden mysteries and potentially discover secret rooms concealed within the town.
The experience is set to have over 70 live actors, making it the capital's largest immersive horror experience.
For the first time, The Nightmare Realm crosses the Irish Sea, bringing its unique brand of cinematic horror to London. But we didn’t come to recreate what you’ve seen before. We’ve come to tell a brand new story. Inside Avery Hill Mansion, A Nightmare From Overseas unfolds through two headline immersive horror attractions, Halloween Town and hidden experiences woven throughout the Realm. Every environment, every character and every encounter has been created exclusively for this chapter. The Nightmare Realm was never built on repeating the same scares. Every year, we build a new world. Every year, we tell a new story. This year…London becomes part of the legend.

Room 13 by Immersive Octopus

Room 13, an original immersive horror experience from Tom Maller (director of Peaky Blinders: The Rise, Doctor Who: Time Fracture, Secret Cinema's Casino Royale, Blade Runner, and Romeo + Juliet), is set to launch at Battersea Arts Centre this October for a two-week limited run.
Inspired by the 2015 fire at Battersea Arts Centre, the 35-minute-long experience, which will feature live actors, special effects and immersive design, will blur the lines between local history and imagined unreality.
In the days following the devastating fire in Battersea Arts Centre on Friday 13th March 2015, a team of builders uncovered a sealed chamber in the original stone structure. When they opened the chamber, what they found was so disturbing that the renovation came to an immediate halt. 11 years later, the door is unsealed once again. The door to Room 13…

Hell's Waiting Room by ScreamWorks

Since their debut in 2022, ScreamWorks has earned a reputation for creating some of London's best immersive horror experiences. Their debut show, Bloodbath, pushed the boundaries of immersive theatre to an extreme and saw visitors being force-fed, tied up, undressed, and chased through an air vent on their hands and knees.
Later experiences, including The Ghost Hunt, had guests make their way through a Victorian house illuminated only by torchlight as they discover the truth behind a family's gruesome murder. While they've been exploring how far they can push escape room-style experiences in recent years, they're going back to basics this October.
For the 2026 Halloween season, they'll be debuting Hell's Waiting Room, an immersive walkthrough experience in which condemned souls await processing into the underworld. Expect big scares, claustrophobic spaces and tough moral decisions. ScreamWorks don't pull their punches, so believe the content warnings...
Since the pandemic, the underworld has become overwhelmed. The queues are endless. And Satan has begun outsourcing the overflow. Hidden behind an old curiosity shop in East London lies Hell’s Waiting Room - a labyrinth of forgotten corridors, condemned souls and eternal limbo, overseen by a man known only as the Collector. Rumour has it that for every soul he delivers, Satan rewards him with another cursed artefact for his ever-growing collection. And tonight… your names have been entered into the ledger.

Hexmoor: Wizarding Prison by Inventive Producutions

Immersive cocktail experience Hexmoor, which comes from the creators of Alcotraz and Moonshine Saloon, is more supernatural than scary, but nonetheless still a solid Halloween outing for those looking for something on the tamer side.
As part of the experience, guests find themselves inside a jail cell serving out a sentence in a wizarding prison under the watchful eye of powerful sorceress Cordelia Constance-Xanthe. As the story unfolds, inmates get to enjoy three Halloween-inspired magical cocktails crafted by a team of mixologists, travel through an ethereal portal hidden within a fireplace and collude with fellow inmates.
According to Sam Shearman, creator of Hexmoor and founder of Inventive Productions, "Most Halloween attractions are built to frighten you for twenty minutes and send you home. We built something where you stay for longer, in a jumpsuit, with a drink and a story to work out. The threat is real when it arrives, but people book because they want to be in the story rather than run through it."
Your magical misdeeds have led you to a previously unknown wizarding prison. Will you play by the rules and see the light of day again or descend into darker depths? Explore Hexmoor, and you will find out soon enough. Experience a world of mysticism and alchemy at Hexmoor, the world’s first immersive, wizarding prison bar. Don your official jumpsuit and rub shoulders with the notorious dark arts wizards who call Hexmoor home.
