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 is one of the world's largest steel arch bridges. 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, the Sydney skyline and the Opera House.

Although some former visitors complained of the high price tags, many said the bridge climbs are the best way to experience this iconic attraction, calling it a must-do experience. While climbs are offered throughout the day every day, travelers recommend scheduling a climb at twilight, which will give you three different views – daylight, sunset and nighttime – in one. If you're afraid of heights, reviewers still suggest you consider the experience as the staff is well-trained to help you overcome your anxieties.

To get to the Sydney Harbour Bridge, visitors can take a ferry beneath it, drive or walk through it, or climb to the top of it. Bus and train drop-offs, metered parking and several parking lots are also available near Circular Quay. The Coathanger is free to view and walk across, but there is a toll to drive on the bridge, as well as a one-way fare for ferries. The most expensive option, the bridge climb, costs between AU$168 and AU$403 (about $119 to $285), depending on the season, time of day and type of climb. Each bridge climb fee includes a complimentary group photo and BridgeClimb cap. Restrooms and a gift shop are also available within the BridgeClimb Sydney visitor center.
