The Blue Mountains is a UNESCO World Heritage gem just a short hop from Sydney, known for its eucalyptus forests, sandstone cliffs, thundering waterfalls and wildlife that actually looks excited to see you. The region is part of the Great Dividing Range and gets its iconic blue haze from tiny eucalyptus oil droplets hanging in the air. It’s got that magic, moody look even on sunny days. Travellers come for cosy mountain towns, hiking trails for every level and jaw-dropping viewpoints like Echo Point, home to the famous Three Sisters. If you’re chasing fresh air and big scenery without going off-grid, this is your spot.
