The beautiful Blue Mountains are situated in New South Wales, in Sydney, and are one of the most remarkable attractions in Australia. This mountain range, which is spread over an area of 11,400 square kilometres, was formed from a sandstone bedrock from a dissected plateau.It is situated in the Sydney Basin and after millions of years of evolution, they are now a series of ridge-lines, separated by gorges as deep as 760 metres.The Blue Mountains are fringed with the Hawkesbury and the Nepean rivers in the east, and Lake Burragorang in the south and the Cox river in the west.The Colo River flows on the north side of the mountains. Several popular towns, like the Blackheath, Mount Victoria, Springwood and Katoomba are situated in the intersections of this region.The most striking natural feature of the Blue Mountains is the vast expanses of eucalyptus rainforests.The name of the mountain range is derived from the brilliant blue haze of the mountains, which is created by tiny, suspended droplets of eucalyptus oil released from the eucalyptus trees that grow on the face of these hills.The Blue Mountains have been declared a World Heritage Area in 2000 by UNESCO due to the significant role of the eucalyptus forest, which have been stabilizing the environment and climate of Australia since prehistoric times.There are many interesting places you can visit in and around the Blue Mountains, including the Three Sisters rock formation, which you can observe from the Echo Point Lookout at Katoomba.This place is a confluence of many thrilling walking trails and valleys, which is why it attracts a number of tourists from all over the world. The ancient Jenolan Cave can also be found on the Blue Mountains, which has spectacular limestone crystal formations and underground rivers dating back to 340 million years.
Another key aspect of the Blue Mountain Range is that it is home to almost 400 different species of indigenous animals, the most predominant being koalas, spotted-tailed quoll, grey kangaroos, long-nosed potoroo, yellow-bellied glider, Blue Mountain water skink and several rare reptiles.
