Greater Blue Mountains Area

The Greater Blue Mountains Area is a World Heritage property in New South Wales, Australia, recognized for its extensive eucalyptus-dominated ecosystems, endemic species and dramatic sandstone landscapes. The listing covers a large swathe of plateaus, gorges, canyons and protected reserves to the west of Sydney.

Visitors use a network of lookouts and walking tracks to view features such as the Three Sisters, deep valleys like the Grose Valley and waterfalls around Katoomba and Wentworth Falls. The area is valued for bushwalking, canyoning, rock-platform lookouts and biodiversity observation.

Aboriginal peoples have occupied and managed these landscapes for many thousands of years; European exploration and pastoral use followed in the 19th century. The property was inscribed on the World Heritage List in 2000 for its natural values.

The Greater Blue Mountains lie to the west of the Sydney metropolitan area, generally beginning around 50 kilometres from central Sydney and extending across a broad upland region in New South Wales.

• Area: Covers roughly 10,000 square kilometres of plateaus, escarpments and gorges west of Sydney and is notable for its diversity of eucalypt species.
• Crowd tip: Best-known lookouts are busiest on weekends; early morning or weekdays give quieter access and better light for photography.
