Aquaventure

Aquaventure is a water park just outside Cirencester, so if you're camping at Hoburne Cotswold or one of the other sites nearby, it's within easy striking distance for a day out. The park delivers what you'd expect from a commercial water attraction - slides, pools, splash zones - though it's not enormous, which means you won't spend an entire week here. Families with young kids will find it decent enough for half a day, especially if the weather's warm and the queues aren't mental. Older children might get bored after a couple of hours unless they're genuinely into water slides.

The real value here is convenience rather than spectacle. You're not driving two hours to some world-class destination; you're filling an afternoon while staying put in the Cotswolds. That said, if you're basing yourself near Cirencester and the kids are restless on a rainy day, Aquaventure beats sitting in a static caravan. Admission details aren't publicly listed online, so ring ahead before you visit - that'll also tell you whether it's worth the trip on the day you're planning to go. School holidays tend to be rammed, so off-season visits are sensible if you hate crowds. Allow two to three hours maximum unless you're genuinely committed to every single slide. It works well as an add-on to a Cotswolds park holiday, not as the main event.
