 Scenic World also offers the Scenic Skyway cable car, which travels over an arm of the Jamison Valley and offers views of Katoomba Falls and Orphan Rock.In 2004 the original Skyway car was replaced by a new car with a liquid crystal panel floor, which becomes transparent while the car travels.In 1983 construction began at the site on a roller coaster called the Orphan Rocker; the track was completed, but this attraction has never been opened to the public.
