The Blue Mountains When the Eucalyptus Makes the Haze

The Blue Mountains When the Eucalyptus Makes the Haze

The Blue Mountains begin ninety minutes west of Sydney by train, and the name is literal — the eucalyptus oil released by millions of gum trees refracts the light and turns the air blue, a natural phenomenon that makes the valleys look like they've been painted with a wash of cobalt. Katoomba is the main town, and the Three Sisters — a rock formation of three sandstone pillars rising from the Jamison Valley — are the view that brings the day-trippers.

The Giant Stairway descends 900 steps from the Three Sisters lookout to the valley floor, through rainforest that feels prehistoric — tree ferns taller than houses, lyrebirds mimicking chainsaws in the undergrowth, and the kind of silence that only dense forest can produce. The Scenic Railway (the world's steepest incline railway) brings you back up if your knees protest the return climb.

Practical notes: Take the train from Central Station to Katoomba (2 hours, runs hourly). The Blue Mountains Explorer Bus connects the major lookouts and trailheads from Katoomba station. Bring layers — the mountains are 1,000 meters higher than Sydney and noticeably cooler.
