The Three Sisters are an unusual rock formation in the Blue Mountains of New South Wales, Australia, on the north escarpment of the Jamison Valley. They are close to the town of Katoomba and are one of the Blue Mountains' best known sites, towering above the Jamison Valley. The Aboriginal dream-time legend has it that three sisters, 'Meehni', 'Wimlah' and 'Gunnedoo' lived in the Jamison Valley as members of the Katoomba tribe. These beautiful young ladies had fallen in love with three brothers from the Nepean tribe, yet tribal law forbade them to marry.
