They really are blue! We went on a day trip from Sydney. Having been I would probably have preferred a day and a night as it was stunning!
We took the incline train down to the bottom and went for a walk through the forest.
The viewpoint overlooking the Three Sisters was a bit of a scrum but truly stunning.
Rounding off the day with a poke around the pretty town of Leura.
And a very expensive beer in a lovely, shady cafe.
