Long a feature of this area, the glass-bottomed Skyway carries you across the Jamieson Valley from Scenic World's main building to Echo Point near the Three Sisters rock formation. (Earlier incarnations of the Skyway used rather more rickety carriages like the one shown in image 13997.)
Unfortunately we didn't get to ride this; it appears that the carriage can contain around 40 people per trip but it was pushing 4pm by the time we tried to get on it and there were many, many carriages worth of people ahead of us in the queue. And after we'd ridden it, we'd have to have ridden it back before closing to get back to the car. It's a pity, because it is indeed quite the experience as I recall from my previous trip.
