A well-organised and dizzyingly exciting outing. You don grey jumpsuits, strap yourself onto a wire, then walk out underneath the bridge, up a ladder, along one of the curves to the top of the bridge, across the bridge and back down the opposite curve. From the top you see one of the greatest views in the world. Do the climb at night and see the same view with the lights on. Breathtaking.
