The Sydney Harbour Bridge stands next to the Opera House as one of the city's most iconic landmarks. Lovingly called the "Coathanger" by locals, this towering structure holds the distinction of being the world's largest steel arch bridge. And while you can capture stunning pictures of the bridge from one of Sydney Harbour's ferry boats, for an unforgettable experience, sign up for a bridge climb through BridgeClimb Sydney. Ranging from nearly two to nearly four hours in length, the bridge climb provides visitors with panoramic views of the Harbour, Sydney skyline and Opera House.
