I had to pick up my daughter from Katoomba today so I decided to stop at the three sisters rock formation. It was 5 Degrees Celsius and no lie the wind was gale force and terribly cold. The blue mountains are approx. 1000mts elevation so not very high up but the cold wind coming up off the mountains was so cold and I was so unprepared for it. My daughter said she had to drive past snow to meet up with me and it didn’t surprise me.It is very pretty but very prone to fires. As soon as it catches fire there is no stopping it with the wind fanning the blaze. I took these two 360 Degree photo’s though next time I will video it.
