The Three Sisters is a stone development in the Blue Mountains of New South Wales, Australia, on the north ledge of the Jamison Valley. They are near the town of Katoomba and are one of the Blue Mountains' best known locales, towering over the Jamison Valley.Their names are Meehni (922 m), Wimlah (918 m), and Gunnedoo (906 m). The magnificence of the Blue Mountains is covered in a cloak of puzzle and extraordinary common wonder. Consistently sightseers run to remain in amazement at the bizarre rock arrangements cut from the bluffs at Echo Point in Katoomba. These three grand rocks catch the daylight and burst with shading for the duration of the day, notwithstanding when the sky surges with night the otherworldly three sisters sparkle gold against the velvet background.
