Warner Bros. Studio Tour London is bringing back Nox, its after-hours Halloween event, for three nights this October: the 29th, 30th, and 31st, 2026. Tickets are £150. During Nox, guests explore the studio’s authentic Harry Potter sets after dark during the Dark Arts feature, come face to face with Death Eaters, walk a lantern-lit Forbidden Forest, and collect trick-or-treat sweets along the way.
Step into the shadows and delve into the dark arts during this spine-chilling, after-hours event.
The Studio Tour describes the night that way.
Inside the Great Hall and the Dark Arts Feature
The night begins in the most famous room in the castle, dressed for Halloween exactly as it appeared on screen.
Explore the authentic Harry Potter sets, props and costumes after hours during the Studio Tour’s Dark Arts feature. Enter the Great Hall under a ceiling of Jack-o-Lantern pumpkins, as seen in Harry Potter and the Philosopher’s Stone. We caution you to be on your guard as Death Eaters could storm Hogwarts at any moment!
The Trail: Forbidden Forest, Diagon Alley, and a Duel at the Hogwarts Bridge
From the Great Hall, guests are sent on a trail through the darkened Studio Tour, stopping at trick-or-treat stations for sweets inspired by the films. The route runs through some of the series’ most atmospheric sets.
Dare to enter the Forbidden Forest? You’ll find your path is only lit with lanterns against the fearsome creatures who lurk in the shadows.
The Death Eaters take over from there.
Throughout the evening, a heightened number of Death Eaters will be storming the Studio Tour Backlot. Come face-to-face with Lord Voldemort’s supporters in an epic duel at the Hogwarts bridge.
Guests also stop by Gringotts Wizarding Bank for a bag of chocolate coins before heading down a Diagon Alley patrolled by Voldemort’s followers.
What the £150 Ticket Includes
Each Nox ticket covers:
- After-hours admission to the Studio Tour during the Dark Arts feature
- One misting mocktail or cocktail, served in the Great Hall
- One piece of confectionery at each trick-or-treat station
- A free souvenir digital photograph
- Drink bars are available for additional purchases
Times and Booking
Nox runs on October 29, 30, and 31, 2026. Registration opens from 6:00 p.m., guests experience the Studio Tour after hours from their entry time until 11:45 p.m., and the tour closes at midnight. Tickets are £150 and are booked through the official Warner Bros. Studio Tour site.
At £150, Nox sits well above a standard Studio Tour ticket, positioning it as a premium, once-a-year immersive night rather than a routine visit. It also lands in the same season as Universal Orlando’s Wizarding World Halloween across the Atlantic, where Dark Arts at Hogwarts Castle and the Death Eaters return this fall.
