The Blue Mountains are a UNESCO World Heritage area of sandstone cliffs, eucalyptus forests and waterfalls just west of Sydney. The blue haze that gives them their name comes from the oil of the eucalyptus trees. It’s the most popular day trip from Sydney, and it’s easy and cheap to do by train.
This guide explains how to get to the Blue Mountains, a one-day itinerary, the best lookouts and walks, costs, and whether to take a tour. Train fares and route details come from Sydney Expert (updated October 2026) and Sydney Tourism’s Opal guide (checked October 2026).

One-day Blue Mountains itinerary
- 7:25 – Train from Central to Katoomba.
- 9:30 – Echo Point: the main lookout over the Three Sisters and Mount Solitary. Walk down the Giant Stairway path to Honeymoon Bridge (80 steps) to touch the first Sister (source).

Best walks and lookouts
- Prince Henry Cliff Walk: a 2.3 km clifftop path from Echo Point to Katoomba Cascades, about an hour (source).

Important: as of August 2026, landslide damage had closed sections of the Prince Henry Cliff Walk and the Valley of the Waters (source). Check NSW National Parks alerts before you go.
