The Irish scream park The Nightmare Realm will open in London for the first time in autumn 2026. The event is due to run on 18 selected nights from October 9 to November 1 at the Avery Hill site in Greenwich. Two major horror attractions, Halloween Town and five smaller experiences that will initially remain secret have been announced.
The London edition will not simply reproduce the Dublin programme. The organiser is promoting an original story created for Avery Hill as well as new attractions. The London announcement does not say whether further editions in Ireland are planned.
The Nightmare Realm: From Ireland to London
The Nightmare Realm was founded in 2009. It first appeared in Tralee before moving to Cork and Dublin. The seasonal event combines walk through horror attractions with live performers, elaborate sets and a festival area. In 2023, it won Best Scream Park Event Europe at the ScareCON Awards.
For its London premiere, the organiser has chosen the Avery Hill site in Eltham. Visitors will enter through the gatehouse on Bexley Road, London SE9 2PQ. The late Victorian entrance gate and adjoining lodge are Grade II listed by Historic England.
The attraction name Avery Hill Asylum is part of the event’s fictional story. It does not indicate that a psychiatric institution once operated on the site.
Two Main Attractions for 2026
Secret London was the first outlet to report two new cinematic horror experiences and more than 70 live performers. The official event website has since revealed the names of the two main attractions: Avery Hill Asylum and Sundown Manor. Details about their duration, routes or individual effects have not yet been published.
Avery Hill Asylum
The first attraction carries the subtitle Dr. Thorne is expecting you. The publicly available overview reveals nothing more at this stage. Its name suggests medical or asylum horror but does not provide enough information to identify any specific scenes.
Sundown Manor
The second attraction is promoted with the words The Bloodline Awaits. Its name and subtitle suggest an old family estate with a story centred on a bloodline. The characters, rooms and effects awaiting visitors will remain unknown until further announcements are made.
Halloween Town and Five Secret Experiences
Halloween Town will join the two main attractions. The organiser describes it as a lively world inhabited by characters. Its size in London and the exact shows, food options or entertainment available there are not yet fully known.
Admission will also include five secret immersive experiences. They are deliberately left unexplained and are meant to be discovered around the site. Similar Secret Rooms appeared at previous editions in Dublin. No details about capacity, duration or access have been released for London so far.
The FAQ recommends allowing at least two hours for the full visit. According to the organiser, the actual duration will depend on queues, time spent in Halloween Town and the Secret Experiences visitors discover.

What the Organiser Means by Immersive
The Nightmare Realm describes its two main attractions as story led horror routes with live performance and designed environments rather than brief sequences of isolated scares. Halloween Town and the secret encounters are intended to continue the action outside the two walk through attractions.
For now, this is the organiser’s own description. Whether the different areas will form a coherent story during normal operation can only be judged after the event opens.
Why Scare Actors May Find It Interesting
The division between different types of performance work is particularly relevant for scare actors. The Nightmare Realm is recruiting Scare Actors, Immersive Performers, circus and speciality performers as well as makeup artists for the season. Applicants must be at least 16 when the event begins.
The recruitment notice suggests that the roles will require different performance styles. A linear walk through calls for short, repeatable scenes and precise timing. Open performance areas are more likely to demand improvisation and longer interactions with guests. The organiser has not yet explained how roles will be assigned in London. This distinction is an editorial assessment rather than a confirmed description of the production process.
Dates, Travel and Accessibility
The Nightmare Realm runs on 18 selected nights from October 9 to November 1, 2026. Tickets are sold through an external booking portal. Prices and available time slots should be checked there for the preferred date.
The organiser lists the address as Avery Hill, Bexley Road, Greenwich, London SE9 2PQ. According to the FAQ, free parking will be available on site. Bus route 132 runs from North Greenwich to Bexley Road and Reinickendorf Avenue. The entrance is then a short walk away.
Halloween Town is described as fully wheelchair accessible. One of the two main attractions is also expected to be fully accessible. The other may require a supported alternative route in some sections. The organiser advises against motorised mobility scooters because some spaces are narrow. Visitors should discuss individual requirements directly with the team before booking.
Rules covering minimum age, contact with performers, costumes, photography and health restrictions appear in the FAQ and terms of entry. These details may still change so visitors should check them again shortly before attending.
Conclusion
The London premiere is relevant to our audience because The Nightmare Realm plans to combine classic horror walk throughs with open performance areas and smaller hidden encounters. Its separate recruitment of scare actors and immersive performers also makes the project interesting from a performance perspective.
Many practical details remain unavailable. The confirmed information currently covers the event dates, two named main attractions, Halloween Town, five secret experiences and basic accessibility details. A reliable assessment of the production will only be possible after it opens.
