Mueller Park Play Space

Easily one of the better spots in Subiaco for the under-fives — it’s fully fenced, which makes a real difference when you’ve got a runner on your hands. The water play is the obvious drawcard in summer, but the musical equipment keeps the kids occupied longer than you’d expect. There’s a sandpit, a climbing structure with a slide, and enough shade trees and covered seating that you’re not baking while you watch them. Pack some snags because the BBQ area is genuinely useful, and the picnic tables mean you’re not eating off your lap.
