The Blue Mountains is a rugged region west of Sydney in New South Wales. Known for dramatic scenery, it encompasses steep cliffs, eucalyptus forests, waterfalls and villages dotted with guesthouses, galleries and gardens. Katoomba, a major town in the area, borders Blue Mountains National Park and its bushwalking trails. Echo Point affords views of the storied Three Sisters sandstone rock formation.  Nestled within the wilderness lie charming mountain towns, ancient Aboriginal rock art and the iconic tourist attraction of Scenic World, where a suspended cableway and the world’s steepest train await.
