|As Halloween approaches, families in Yorkshire have a delightful adventure awaiting them at William's Den. This year, the popular attraction is bringing back its immersive Halloween experience, known as Trick or Treat Street, from Saturday 24th to Saturday 31st October. This October promises a brand-new mystery that invites families to become detectives in a fun-filled outdoor adventure.
Exciting Mystery and Bell Hunt
Trick or Treat Street is not just any Halloween event; it combines immersive theatre, Halloween activities, and interactive storytelling. Visitors will journey through a fictional village where they can meet colourful characters, gather clues, and solve puzzles as they seek to uncover the mystery of the village's missing magical chime.


In a creative twist, William's Den has hidden 30 mystery bells at various local businesses across Yorkshire. Families can join in the fun even before arriving at the event. By finding one of these hidden bells, scanning the QR code attached, and sharing a photo on social media, participants will receive a 10% discount on their tickets for Trick or Treat Street. This makes the bell hunt an exciting part of the Halloween festivities.
A Family-Friendly Experience
Now in its fourth year, Trick or Treat Street has established itself as one of Yorkshire's most unique family Halloween experiences. The event is designed to be spooky rather than scary, ensuring children and adults alike can enjoy the magic of Halloween without fright. The event features live performances, interactive storytelling, and plenty of seasonal fun, making it a perfect outing for families.
Once the mystery is solved, there will be even more Halloween-themed activities to enjoy throughout the village of Denville. Families can participate in Detective School, where young sleuths can hone their investigative skills. There’s also a Monster Disco for dancing, opportunities to capture magical autumn photographs, and a fantastic range of seasonal food and drink to savour. Fancy dress is encouraged, with prizes awarded for the best family costumes during the event.
Outdoor Adventure Awaits
Set outdoors amidst a maize field, Trick or Treat Street offers both daytime and evening sessions throughout October. Each child will receive sweet treats as they explore the village, with surprises awaiting them around every corner. This setting provides a magical backdrop for families to create lasting memories together, making Halloween a truly special occasion.
Tor Carver, Co-Founder and Creator of William's Den, expressed excitement about this year's adventure:
“Every year we love creating a brand-new adventure for families, and this year's detective mystery is our most interactive yet. From the moment visitors arrive, they'll become part of the story, meeting our wonderful village characters, solving clues, and helping uncover the mystery of the missing village chime.”
“Trick or Treat Street is all about making magical family memories together. It's spooky without being scary, packed with laughter, live entertainment and surprises, and we can't wait to welcome families back for another unforgettable Halloween.”
