Affectionately known as The Coathanger, the Sydney Harbour Bridge has been spanning the two sides of the water for 100 years. A pedestrian footpath runs along one side of the roadway, offering a unique perspective on the city below. But for the most spectacular views, join BridgeClimb Sydney and head all the way to the top. The thrilling climbs along the arches and to the 134-metre summit run every day and take 2.5-3.5 hours.
