2nd day in Sydney; Blue Mountains

Yesterday we went to the opera house, today we're going to spend the day out in the Blue mountains. They are located about an hour away by bus or car from Sydney. They're called Blue Mountains because Eucalyptus trees release a thin oil, which gives the leaves a blue light, characteristic of the region when they come into contact with sunlight. We're going to use the cable car to cross the valley from one side to the other and from there we're going to see the 3 sisters,  is a tall rock formation with 3 identical columns.

We're going to have lunch in a restaurants at Echo Point, and we're also going to visit some art galleries there.
