While in Sydney, NSW, it is good to visit Blue Mountains area. You can join group package tour but it is more expensive. Decided to see Blue Mountains by taking a train to Katoomba. From Katoomba station, you can ride on local bus to reach Echo Point, where you can view the 3 sisters.
Looking for the train
Two hours travel but looks cozy inside the sub urban train.

Scenic world is a new way to experience blue mountains by skyway, walkway, cableway, railway.
