The Three Sisters are a famous rock formation in the Blue Mountains of New South Wales, Australia. They are close to the town of Katoomba and are one of the Blue Mountains' most famous sights, towering above the Jamison Valley. Their names are Meehni (922 m), Wimlah (918 m), and Gunnedoo (906 m). The only day we were there was fogged in solid. Lucky for the slit in the sky the next morning when we left.
