017 Stand atop of the highest steel arch bridge

If you fancy a workout and aren’t afraid of heights, Sydney Harbour Bridge is calling you.

If you fancy a workout and aren’t afraid of heights, Sydney Harbour Bridge is calling you. At 97.3m, Guinness has it as the widest long-span bridge in the world. And just wait until you’ve climbed it; with the traffic boiling past below and the wind in your hair, it’s a great way of seeing the city from a bird’s eye view.

Since it’s the world’s highest steel arch bridge, you’ll be 134m – and a couple of millimeters extra on a hot day – above mean sea level. The sight is magnificent and blessed are those of you with a photographic memory since there are no cameras allowed on a Bridge Climb.

Where // At the northern end of the CBD. See it? It’s the big coathanger thing spanning Sydney Harbour. (02) 82747777, www.bridgeclimb.com  

Did you know? // The highway leading over the Harbour Bridge is a designated travelling stock route, so technically you shouldn’t be surprised to see cattle on there between midnight and dawn. Although no-one has actually asked permission to herd their livestock across for half a century.
