The summer holidays are heating up with family fun at The Grounds of Alexandria! Our giant inflatable playground is ready for climbing, sliding, and endless laughs. While the kids bounce off the walls (literally), parents can relax in the comfy seating nearby with a takeaway coffee and a treat from The Cafe or The Garden.

This experience is exclusively for children aged 12 years and under. Kids under 5 years must be accompanied by a parent or guardian (aged 18+ years) at all times or consider our soft playground experience for tiny tots. For older children (aged 5+ years), parents and guardians can wait in the seating area but won't be able to join the play.

What to Expect?

Tackle the obstacle course and race through all the twists and turns.
Zoom down the giant slide.
Climb to the top of the inflatable tower for an epic view of the fun below!

Please note that bookings are essential and places will be sold on a first-come-first-served basis, so please act quickly to make sure you don't miss out.

Important Information

Please only buy the tickets you need so more families can join the fun!
This experience is suitable for kids aged 5-12 years. We know every child is different, so use your best judgement to decide if this activity is right for your little one.
All participants must have a purchased ticket and signed waiver before entry. Tickets are only required for children; supervising adults do not need a ticket.
No shoes are to be worn in the Inflatable Playground, but socks are a must! No socks, no play. We don't provide or sell socks onsite, so please come prepared.
This isn't a drop-off service and parents must stay within The Grounds of Alexandria while your child is playing. Please note that children 5 years and younger must be accompanied by an adult (18+ years) at all times.
Can't make it? Refunds are available up to 72 hours before the event.
Refunds cover the face value of the ticket but not booking fees, as these are charged by Humanitix. For details, check out their website.
Please aim to arrive at least 10 minutes before the start of your session, and check in with our staff in Linseed House. Parking and transport in the area can be challenging.
Rain or shine, this event is happening indoors, so don't worry about the weather!
Takeaway food and drinks are available through The Grounds App while you wait, and you can also enjoy dine-in options at The Cafe, The Garden, and The Potting Shed. For a smooth experience, consider making a reservation online before you visit.
