Halloween 2026 | Until 1 November
Who put a spell on Paradox? This Halloween, Paradox Museum London, opposite Harrods in Knightsbridge, has turned into a mischievous playground of clues, spooky tales and magical experiments. Here are five reasons to visit.
1. A mystery to solve
The museum is under an enchantment, and it’s up to families to break the spell. The optional Who Put a Spell on Paradox? Halloween Trail (a £3 add-on) sends you through some of the most intriguing exhibits to uncover clues and find the magic word.
2. Spooky storytelling
From 17 October, interactive Halloween storytelling about witches, spells and potions takes place in the museum’s Dragon’s Nest every 15 minutes between 10am and 4pm. Kids are encouraged to get involved and become part of the story.
3. A real Potion Lab
On selected half-term dates, the Potion Master opens a witch’s laboratory where every ingredient has a magical name and every reaction looks like a spell. Behind the theatre, children explore real science, including density, chemical reactions and gases. It runs from 10.30am to 4.30pm on 23 to 25 October, 30 and 31 October, and 1 November.
4. More than 50 mind-bending exhibits
Beyond Halloween, the full Paradox experience includes more than 50 interactive exhibits and reality-defying rooms, perfect for photos that look anything but ordinary. It was named New Business of the Year 2025 at the Kensington, Chelsea and Westminster Business Awards.
5. Indoor fun, whatever the weather
It’s all indoors, so it’s a reliable half-term option if the weather turns. And being right opposite Harrods, it’s easy to combine with a trip to Knightsbridge or the South Kensington museums.
