Katoomba is the gateway to the Blue Mountains, and the main draw is the spectacular scenery. Echo Point, a short walk from the town centre, gives the classic view across the Jamison Valley to the Three Sisters sandstone formation. From Echo Point, walking trails descend into the valley via the Giant Stairway. Scenic World operates a cluster of rides — the steepest railway in the world, a glass-floored cable car and an elevated rainforest boardwalk — that let you experience the valley from every angle. Beyond the headline attractions, the Blue Mountains offer some of the best bush walking in New South Wales, with well-marked trails through sandstone gorges and eucalyptus forest.
