See the Three Sisters rock formation from Echo Point Lookout at Katoomba; it’s also the gateway to many walking trails. Board the world’s steepest passenger railway and descend into an ancient rainforest with Scenic World Blue Mountains. Or get a panoramic view of the mountains from a glass-floored cable car suspended above a steep gorge.
Tours run daily from Sydney and Katoomba to Jenolan Caves. Scientists estimate limestone formations there date back at least 340 million years. Watch traditional dance performances at Waradah Aboriginal Centre in Katoomba. The Aboriginal Blue Mountains Walkabout tour starts at Faulconbridge train station.
