Award-winning Yorkshire adventure play attraction William’s Den has announced the return of its family festival, Den Fest, running from Friday 17th July to Sunday 19th July 2026.
Following a completely sold-out event last year, the long-weekend feature will expand in 2026 with the addition of a brand-new second stage for performances and activities. The festival, set against the backdrop of the Yorkshire Wolds, offers families the choice to attend for the day or book weekend camping packages. For those looking for a glamping experience, luxury bell tents that sleep up to four people are returning after selling out within three days last year.

The 2026 music lineup features tribute headliners KPOP Kweenz Live! on Saturday and The Ed Sheeran Songbook on Sunday, alongside indie-pop trio Sandra’s Wedding and blues artist Joe Hodgson. Beyond the music, the festival is introducing a variety of new interactive experiences, including Nerf battles, a pop-up petting zoo, baby goat yoga, a reptile roadshow, and a dedicated bushcraft zone for wilderness skills and campfire sing-alongs.
Tor Carver, Co-Founder and Creator of William’s Den, said:
“Den Fest is a proper Yorkshire family festival and a wonderful opportunity for families to experience William’s Den in a completely new way – with a packed festival programme, great food, live music and plenty happening for children and grown-ups alike. As day turns to evening, the campsite comes alive too, with families relaxing together, children making new friends and everyone watching the sun go down over the beautiful Yorkshire Wolds.”
Advance day tickets are priced from £27.45 per person, with weekend camping tickets starting from £82.50 per person. The four-person luxury bell tent package is available for £777.00, which includes weekend festival admission.
