By hop-on hop-off bus
There are also two hop-on hop-off bus services available.
You can purchase a link ticket with the train that includes the Blue Mountains Explorer Bus and the train fare to Katoomba from any Cityrail station. If you are travelling as a family the family fare saver, where only the first child pays, means that you should only buy a link ticket for one child, and buy the other child ticket on the bus.
Consider how much time you have, and what you want to see. HOHO buses will generally cost more money than local buses, especially if you have a MyMulti ticket which includes the local buses.
By train
If travelling between towns in the mountains like from Katoomba to Leura, Blackheath, Medlow Bath, or Mount Victoria, train is also available. Trains generally run every hour or so, more frequently during peak times.
By Local Bus
You can get to some stunning view points near Katoomba and Leura falls using regular bus service. Buses stop right outside the train station. Visit Blue Mountains Bus online (http://www.bmbc.com.au/) for the timetable. Most popular visitor destinations are serviced, but service frequency can drop to every couple of hours on Saturdays and many routes don't run at all on Sundays.
Any type of MyMulti ticket will cover the local bus in the mountains - buy one from a ticket reseller or a train station. Cash tickets are sold on the bus.
By car
Once you get up the mountains, it is easy to get around the mountains by car, and congestion or parking is generally not a problem in getting around. The Great Western Highway A32 crosses the Mountains east to west, and most places aren't far from it. Expect to pay for parking at Echo Point The Three Sisters at $4 per hour, but everywhere else should be free of charge. There are large free multi-storey parking lots at Scenic World.
Local Car Rental is available from RediCAR (http://www.redicar.com.au/), but if you are coming from Sydney, driving up the mountains is a good option.
