Climb Sydney Harbour Bridge, Australia
Top off a visit to one of the world’s most beautiful cities with a windswept shinny up unmistakeable Sydney Harbour Bridge. Clamber around the upper arch by way of narrow catwalks and ladders to enjoy 360-degree views of Sydney Harbour, the ocean and the Opera House from a height of 134m. You can even sign up for a night climb, and lap up the sight of Sydney's lights reflected in the harbour; just watch your footing.
