Good to know about the blue mountains. The Blue Mountains has a convenient hop-on, hop-off bus that departs from Katoomba train station, or there are public buses that you can use to get around Katoomba and the nearby attractions.

If you feel you should visit this place in groups, the tourist department of the Blue Mountains will give you a guided trip that starts right from the Sydney metro, or if you wish to spend more, go to a tour agency.
