Blue Mountains

The Blue Mountains is a mountainous region in New South Wales, Australia. It borders on Sydney's metropolitan area, its foothills starting approximately 50 kilometers west of the state capital. The area begins on the west side of the Nepean River and extends westward as far as Coxs River.

Blue Mountains is one of the greatest tourist attraction which attracts so many visitors from around the world to visit and feel the majestic beauty of this natural mountainous region. The people who live in Australia are well familiar with the beauty of this place.

The climate varies with altitude. At Katoomba (1,010 m) summer daytime temperatures are usually in the 20s with a few days extending into the 30s (Celsius). Night-time temperatures are usually in the teens. During the winter the temperature is typically around 12 to 13°C in the daytime with −3°C or so on clear nights and 2 to 3°C on cloudy nights.

Last year it was my fifth time I went to the Blue Mountains in Sydney its really enjoyable journey and interesting with gorgeous natural views.

Why The Area Is Blue?

The area is called Blue Mountains due the bluish appearance of the whole region. Now this bluish appearance has a direct link to the Eucalyptus trees covering the whole area.

These trees are actually called Eucalyptus Globulus and are covered with a waxy substance called 'blue gum'. When atmospheric pressure rises in the Blue Mountains, this waxy substance evaporates and disperses in the air. The sunlight after passing through the vapour reflects back blue light from its spectrum of seven colours. Therefore the whole area appears bluish.
