Between Sydney Observatory and the Harbour Bridge is a patch of bouncy turf that’s surprisingly well equipped. There are three zones with vaulting bars, sit-up benches, pull-up rings and stretching poles – plus a bubbler, a couple of resting benches and public toilets only minutes away (down the hill). Instructions boards guide you on how to use the fitness equipment, and there are handy charts for how many reps you should aim for depending on your age. It’s a meeting place for personal trainers and their clients, but it’s underused even on weekends. You don’t really get harbour views, but you’re close enough to the Bridge to incorporate some stair training and a few hill runs. It’s only partially shaded so pack sunscreen.
