Explanation:

[STC002550] The Blue Mountains in Australia are shrouded in a mist that has a bluish-violet hue. And what exactly is the source of that haze? eucalyptus trees emit a vapor that can be inhaled. The leaves of the trees exude tiny drips of oil, which, when combined with the water vapor in the air and the light from the sun, produce this dazzling hue. Walk the paths through beautiful eucalyptus forests, discover waterfalls and caverns, and see traditional dance performances at the Waradah Aboriginal Centre in Katoomba when you go to the Blue Mountains, which are located just outside of Sydney.
