The Ghan takes guests from Darwin to Adelaide or vice versa, traveling through Alice Springs and the heart of Australia. This journey is considered one of the great train journeys of the world and is aptly named after the Afghans who ran the camel trains between northern and southern Australia.

The Indian Pacific connects Australia’s east and west coast from Perth to Sydney. The journey meanders through the Blue Mountains, Adelaide and across the ever-changing outback along the inspiring Nullarbor Plain.

The Southern Spirit travels between Adelaide and Brisbane. The Southern Spirit explores the path less traveled, allowing guests to take in the sights of four Australian states as it winds through the Great Dividing Range and along Australia’s Eastern Seaboard. Each train journey will make whistle stops at a variety of Australia’s top destinations including Byron Bay, Alice Springs, The Grampians, Darwin and Adelaide, offering excursions on each route.
