The Blue Mountains in New South Wales embrases 26 townships in an area of 1433 square kilometres. The townships are situated from 50 to 120 km west of Sydney and are within 1,000 square kilometres of this World Heritage listed National Park.
It was declared a World Heritage park in November 2000. It was nominated for its outstanding natural values, including the biodiversity of its plant and animal communities, its vegetation, which is dominated by Australia's unique eucalypts, and for the beauty of its natural landscapes.
It was so named because, from Sydney, It look blue. It is clad in vast forests of eucalypts (commonly called gum trees), which in the hot sun discharge a fine mist of eucalyptus oil from their leaves. The mist refracts light, which makes the haze look blue at a distance.

The Three Sisters are 922, 918 & 906 metres tall, respectively.
There is a Legend that three sisters, 'Meehni', 'Wimlah' and Gunnedoo' lived in the Jamison Valley as members of the Katoomba tribe. The beautiful young ladies had fallen in love with three brothers from the Nepean tribe, but tribal law forbade them to marry. The brothers were not happy to accept this law therefore decided to use force to capture the three sisters causing a major tribal battle.
As the lives of the three sisters were seriously in danger, a witchdoctor from the Katoomba tribe took it upon himself to turn the three sisters into stone to protect them from any harm. While he had intended to reverse the spell when the battle was over, the witchdoctor himself was killed. As only he could reverse the spell to return the ladies to their former beauty, the sisters remain in their magnificent rock formation as a reminder of this battle for generations to come.
