Australia's Sydney Harbour Bridge is the world's tallest steel arch bridge, and the world-famous Sydney Opera House across the sea has become one of Sydney's most well known symbols. Since 1998, the Sydney Bridge has been open for climbing under the guidance of professional coaches. The bridge has been erected 134 meters from the sea. The 360-degree view of the Sydney Opera House, Sydney Harbour and the city skyline can be seen from a unique perspective. The busy boats and the vehicles coming and going on the bridges will make Sydney's most beautiful scenery unobstructed.
