Yes, it's the Three Sisters that is usually on calendars & visited by tourists in the Blue Mountains, although there are many spots to visit around the Mountains.

View from Scenic World (deck above Scenic Cableway) of the Three Sisters on the left & Mount Solitary to the right with mists (sunken clouds ) in the Jamison Valley.



For an idea of scale you may notice (or just barely make out) a small bridge to the first of the Sisters & this is what it looks like up close (cropped).



BTW, the brown area around Mt Solitary is where a hazard reduction burn was done a couple of months prior to the photos taken.
