This week-end, we decided to visit the Blue Mountains with some friends. They consist in a sandstone plateau riddled with steep gullies eroded by rivers over thousands of years, and are about 30 miles away from Sydney. They're called the Blue Mountains because of the blue hazes you can see on the pics. It actually comes from the evaporation of eucalyptus trees' oil!
This place was absolutely breathtaking and huge. Two days were far not enough to see everything. We walked a lot, it was really exhausting, but beautiful! Check the pics if you doubt it!
