Tickets go on sale today for a new experience launched by BridgeClimb in Sydney, Australia.

The company, which offers the chance to climb Sydney Harbour Bridge, is opening up sections of the bridge not previously accessible to the public with a new tour called The Discovery Climb.

Climbers will ascend upon an inner arch, surrounded by the structure of the bridge, rather than walking along the top, and will get to see the point where the bridge was first joined.

To reach the summit, 134m above sea level, discovery climbers will scale a staircase starting 116m above sea level.

The new tour will take the same amount of time as the existing Bridge Climb experience, about three and a half hours. Details: www.bridgeclimb.com
