Getting Around
Trains on the Blue Mountains Line from Sydney Central Station reach Katoomba in roughly two hours and run regularly throughout the day. Within the mountains, the Blue Mountains Bus Company and the hop-on hop-off Explorer Bus connect major villages and lookouts with reasonable frequency.
⚖️
Cash or Card
Card payments are accepted almost everywhere across the Blue Mountains, including cafes, hotels, and the major attractions, and contactless tap-and-go is the default expectation. Carrying a small amount of Australian cash is still useful for farmers markets, some trail-adjacent food vans, and the occasional heritage-style tearoom that prefers the old ways.

Good to Know
The Blue Mountains operates on a genuinely slower rhythm than Sydney, and locals appreciate visitors who match that pace rather than treating the area as a rushed day trip. Weekends draw large crowds to Echo Point and Scenic World, so midweek visits reward travellers with quieter trails, easier cafe seating, and a calmer atmosphere at the major lookouts.
🏧
ATMs
ATMs are available in Katoomba and Leura town centres, typically attached to the major bank branches along the main shopping streets. Smaller villages such as Blackheath and Wentworth Falls have limited ATM access, so withdrawing cash before exploring the outer reaches of the plateau is a sensible precaution.
💳
Currency
The Australian Dollar (AUD) is the currency throughout, issued in polymer banknotes of 5, 10, 20, 50, and 100 dollars alongside coins in denominations of 5, 10, 20, and 50 cents and 1 and 2 dollars. Prices in the Blue Mountains tend to carry a modest premium over urban Sydney, particularly for accommodation and dining at the higher-end heritage properties.
🔌
Plugs
Australia uses the Type I outlet, a flat three-pin angled plug running at 230V and 50Hz. Visitors from North America and Europe will need a plug adapter and should check device compatibility for the voltage difference.
🛡️
Safety
The Blue Mountains terrain is serious and the weather changes quickly, with fog, rain, and cold snaps arriving without much warning even in summer, so carrying layers and informing someone of hiking plans is standard local practice. The cliff edges at many lookouts are unfenced and the sandstone can be slippery when wet, requiring careful footing and respectful distance from the drop.
✈️
Airports
Sydney Kingsford Smith Airport (SYD) is the primary international gateway, located approximately 110 kilometres east of Katoomba and accessible by train with a change at Sydney Central Station for a total journey of around two and a half hours. There is no commercial airport within the Blue Mountains itself, making the Sydney train connection the standard and most practical arrival route for all visitors.
