The Blue Mountains most famous landmark is Three Sisters. These dramatic rock columns form a ridge jutting into the northern edge of Jamison Valley. Let’s meet the girls. On the left is Meehni, the tallest at 3,025 feet. The middle child is Wimlah at 3,012 feet. Baby sister is Gunnedoo at 2,972 feet. According to a Dreamtime legend, these siblings were part of the Kotoombra clan. Their father turned them to stone to protect them from three suitors belonging to the rival Nepean tribe. When he died, no one could bring the three sisters back to life. Many believe this story was a marketing scheme created in the 1920s.
