Katoomba Scenic World is a very popular visitor destination in the Blue Mountains. It offers three rides including Scenic Cableway. This visually-exciting cable car – Australia’s steepest – descends 1,673 feet down the escarpment. When you disembark, you arrive at Scenic Walkway. This is a 1.5 mile, raised boardwalk through the dense rainforest. This easy path lets you experience the unique flora of the Blue Mountains.
