William’s Den is an absolute gem for families who love a bit of adventure and getting stuck into nature. You’ll find this award-winning indoor and outdoor play space in North Cave, East Yorkshire (HU15 2LS).
What’s the vibe?
Think of this as the ultimate “back to basics” play experience, but executed on a massive, high-quality scale. It’s specifically designed for children, though adults are encouraged to get involved too! The whole place is built with wood, stone, and water, focusing on physical play rather than flashy screens or plastic.
The Fun Stuff
The Indoor Den: This isn’t your average soft play. It’s a huge bespoke timber structure featuring a 6-metre high “Treehouse,” a “Rain Room” where kids can play with water (bring a change of clothes!), and plenty of tunnels and climbing nets.
The Outdoor Adventure: Outside is where the energy really ramps up. There are huge sandpits, zip wires, massive slides, and a mud kitchen that is always a hit with the younger ones.
Special Events: They often host themed activities, especially during the school holidays (usually around October for pumpkins or December for festive fun), which can add a bit of extra magic to the day.
Insider Tips & Budgeting
Food & Drink: The food on-site is actually really good—think wood-fired pizzas and homemade ice cream. However, it can add up for a large family. There are designated spots if you want to bring a packed lunch to keep costs down.
Stay or Go? Most families easily spend 4 to 5 hours here, and many stay the whole day. If you live locally, their annual memberships are a total winner as they pay for themselves in just a few visits.
Save a Few Quid: Keep an eye out for “After School” deals or “Toddler Sessions” during term time which are significantly cheaper than weekend peak slots. Booking online in advance is usually the best way to secure your spot and sometimes offers a small saving compared to the gate.
Parking: There is plenty of free parking right on-site, so no need to worry about trekking from a nearby village.
Nearby Combines
If you have any energy left, you’re right on the edge of the Yorkshire Wolds. You could combine a morning here with a gentle walk around North Cave Wetlands just down the road, which is a lovely, level spot for a bit of birdwatching and fresh air to wind down after all that climbing!
