Katoomba developed as a popular mountain resort town in the early part of the 20th century, a process aided by the advent of regular train services along the current line. The town reached an early heyday in the period between the wars, attested to today by the numerous examples of art deco architecture and shop fronts along the main street of the town.
Katoomba is located just off the Great Western Highway between Sydney and Bathurst. Parking fees are charged at Echo Point and availability is limited; consider parking at Scenic World, which offers free parking in its large car park.
Hourly CityRail  services run from Sydney and its western suburbs.
From Sydney Central the cost of the adult train fare is $12.20 single peak, $16.80 off-peak day return  and the one way trip time is about two hours. The train gets you to the centre of Katoomba.
From the train station you can take a hop on/hop off bus or trolley/tram around the sights for between $12 and $27 depending on which company you choose to go with.
Blue Mountains Trolley Tours  charges $20 for a day's hop-on/hop-off (around 9 a.m. to 5 p.m.) but ask nicely at their sales office near the train station and you may get stamps for extra days for free.
The Blue Mountains Bus Company's Route 686 also brings you to various tourist attractions. 
Echo Point lookout has spectacular views of the Three Sisters.
The Edge cinema, 225 Great Western Highway, tel 02 4782 8900. The main attraction of The Edge cinema is a 38-minute giant screen movie about the Blue Mountains, called Wild Australia: The Edge. This is an amazing show about the stunning scenery and the rainforest, filmed from an "adventure sports" and "conservation" viewpoint... not at all tacky or "touristy". The Edge cinema also screens other giant screen films and conventional movies including classic films, so be sure to check the schedule before making the trip.
Scenic World, Corner of Violet Street & Cliff Drive, ☎ 02 4782 2699 (firstname.lastname@example.org, fax: 02 4782 5675), . The Scenic Skyway and Scenic Railway have been part of a visit to the Blue Mountains for as long as any Sydneysider can remember. The scenic railway is a really steep caged railway, and gives quite a thrill. The front seat is best if you can get it. The scenic cableway is much more sedate as descends down into the forest, and although it is common to do the railway down and the cableway back, if you want to enjoy the ride and not just the view, you'll have more fun just taking the railway both directions. Down in the valley you can walk on boardwalks along in the rainforest, the avalanche and see some mining remnant artifacts. There can be crowds on weekends, but you'll still get on okay. There can be school groups too, so just have a cup of coffee and wait for them to do their thing.$10 each way. edit

The Clarendon Guesthouse, 68 Lurline St, . Has a licensed entertainment restaurant which features live music, comedy and theatre.
Traditional pubs, less heavy on live entertainment than the Clarendon, cluster around Katoomba railway station. The nightlife is this area is not fantastic - by 9PM on a Friday night the streets are almost empty - but those looking for a drink should try:
The Carrington Piano Bar, also known as the Saloon Bar. The most upmarket of the pubs, it contains rather less drunken young people than the others on the average Friday or Saturday night. Sometimes has live piano music. It also has an excellent restaurant upstairs.
The Carrington Main Bar is the 'default', stock-standard Katoomba pub, generally known as the 'Carrington' or just the 'Carro'. It's located just opposite the train station and taxi stand. Poker machines, beer, pies, more beer. It has a recently-renovated nightclub upstairs (with a separate entrance fee) called 'Baroque', which features live music on many nights.
The Hotel Gearin is another beery pub on the opposite side of the railway line to the Carro. It was previously very rough, with the occasional brawl, but its new owner, the actor Jack Thompson, has been working to take it upmarket with live music and so on.
All live music venues in Katoomba publish advertisements listing their upcoming attractions in the entertainment section of the Blue Mountains Gazette, which is published on Wednesdays and can be bought at newsagencies.
