This addition to the Sydney thrill scene is a heart-stopping experience that is definitely not for people who are scared of heights. The deal is, you don a special suit, walk out onto a glass-floored platform 260m (853 ft.) above the city floor and walk around the building. The views are breathtaking (even between your feet!). You are harnessed to a safety rail with a sliding harness, so there's no chance of falling off, and funny, well-informed guides offer a helping hand to the nervous. Each Skywalk lasts approximately 1 hour and 30 minutes and operates daily from 9am to 10pm, with the last Skywalk departing at 8:15pm. Cameras aren't allowed for safety reasons, but group or individual shots help clean-out your wallet. Children under 10 aren't allowed on the Skywalk.
