King George’s splash park

On a hot day in Brentwood, this splash park is genuinely one of the better ways to keep the kids cool without spending a fortune. The water features are well-maintained, and the staff here are actually friendly — not just going-through-the-motions friendly. You’ve got enclosed play space, clean loos, and parking sorted, plus an open grass field for when the little ones need a breather between soakings. All ages can make a day of it, which is rarer than you’d think for somewhere like this.
