This majestic piece of the UNESCO World Heritage listed Blue Mountains is a true escape from city life, with 300-year old Mountain Blue Gums towering above a lush undergrowth. The brutally steep decent delivers you to the intimate forest, with ochre coloured cliffs cradling the enchanting eucalypts. Blue Gum Forest is now a cherished destination for hikers from Sydney and the surrounds.  It has attracted numerous conservation efforts from the late 1800s, and was saved by the intrepid Sydney Bushwalkers club in the midst of the Great Depression when they scraped together £130 to secure forest from being toppled for a walnut grove.
