Grant Marine Park Playground

Honestly, the location here is hard to beat — you’re basically at the beach without being on the sand. It’s a simple setup: open grass, a few shade trees doing solid work on a hot Cottesloe afternoon, and enough benches that parents can actually sit down for five minutes. Kids who need room to run have plenty of it, and the whole thing is relaxed enough that you’re not fighting for space even on a busy weekend. Pack a picnic and make a day of it — the beach is right there.
