For visitors travelling from overseas, the nearest airport is Sydney Airport. From there, the best means to travel to the Blue Mountains is by car - about a 50-minute drive to the entrance at Glenbrook. Follow the signs to Parramatta and take the M4 Motorway at Strathfield through to Lapstone and the Blue Mountains. The trip to Leura or Katoomba takes about 90 minutes from the airport. If you're travelling by car, take the M4 Motorway out of Sydney or take the longer, meandering route via Windsor and Kurrajong along the Bells Line of Road. The rise from the coastal plain begins at Glenbrook, 65km west of Sydney, and the road passes through many small towns along the way to Leura, Katoomba and on to Blackheath. The iconic rock formation known as the Three Sisters is at Echo Point, Katoomba. Alternative routes will take you on a more scenic path via Bells Line of Road through Richmond and Mount Tomah, to Bell and across to Mount Victoria. It’s a delightful drive and a different introduction to the vast Blue Mountains National Park compared to the Great Western Highway. If coming from the outer west, follow the signs to Lithgow, go through Hartley and enter the Blue Mountains through Victoria Pass which will take you straight to the top of Mount Victoria.
