The Nightmare Realm runs on selected nights from 9 October to 1 November 2026 at Avery Hill, Greenwich. The London production is a new chapter created for this location rather than a copy of earlier Irish editions.
Overview
After more than 16 years of creating Halloween experiences in Ireland, The Nightmare Realm is crossing the Irish Sea for its first London season. The attraction blends immersive theatre, cinematic horror, live performance and detailed environments across a wider living world rather than a simple haunted-house walkthrough.
For anyone in Greenwich, Eltham and the wider South East London area who usually has to travel across London for a large-scale Halloween scare attraction, this is a particularly exciting local arrival.
What to Expect
Your ticket includes two large headline immersive horror experiences alongside five secret experiences hidden throughout the wider Realm. The event is designed around live actors, storytelling, special effects and cinematic environments, with Halloween Town linking the different parts of the experience together.
The official event information advises visitors to expect darkness, loud sound effects and uneven ground. Photography is not permitted inside the attraction.
