9. Golden Gate Bridge, San Francisco

Another San Fran entrant and the only other bridge to have beaten our Sydney Harbour Bridge, the Golden Gate Bridge is named so as it spans the Golden Gate strait, connecting the city to Marin County.

21. Machu Picchu, Peru

Perched high up on a mountain and accessible by foot or by a long, windy ride, Machu Picchu is the Ancient City of the Incas which remained hidden only up until the last century. If you’re fit as a fiddle, brave the 2-day Inca Trek through the jungle and wake up to the city as it glows with the sunrise from the Sungate.
