Giant inflatable assault course returning to William’s Den this May

An award-winning Yorkshire adventure play attraction, William’s Den, will be springing into the May bank holiday weekend with the return of ‘The 175’, from Saturday 4 to Monday 6 May.

At 175m long, the giant blue inflatable is one of the longest in the North. It’s home to obstacles to blast through, a rope to swing over, hills to clamber up and three slides to zoom down. Twin-tracked, it’s the perfect place to race friends and family, with as many goes as you like.

As well as taking on The 175 inflatable, visitors to William’s Den can spend the bank holiday enjoying unlimited, all-day indoor and outdoor play with sand pits, water streams, mud kitchens, football and den-building, plus fun activities and guided play with the William’s Den Play Pioneers, who encourage play so that children can get as much out of their day at the Den as possible.

Tor Carver, Co-Founder and Creator of William’s Den, said: “Having The 175 here last year was unforgettable and we’re so excited for its return this May bank holiday. It’s a brilliant way to make memories with family and friends while getting outside in the fresh air. Last year’s event was a sellout, so I’d recommend booking tickets quickly to avoid disappointment!”

The 175 will be at William’s Den on Saturday 4, Sunday 5 and Monday 6 May. Tickets are now available to book at www.williamsden.co.uk/return-of-the-giant-175-inflatable 

William’s Den was named East Yorkshire’s Visitor Attraction of the Year for the second year running in the Remarkable East Yorkshire Tourism Awards in 2023. The Den was also named Environmentally Friendly Business of the Year at the Goole & Howdenshire Business Excellence Awards 2024.
