context_page_description: The Blue Gum Forest is a forest located in Blue Mountains National Park within the Grose Valley of the Blue Mountains in New South Wales west of Sydney, southeastern Australia. It is one of the best-known bushwalking sites in Australia. The forest is located within the UNESCO World Heritage Site known as the Greater Blue Mountains Area. The forest survived through the efforts of early Australian conservationists.
context_section_description: The forest consists predominantly of towering Mountain blue gum (Eucalyptus deanei) trees, with an understory of shrubs. The forest can be accessed only on foot, with several trails from different parts of the Grose Valley and adjacent canyons meeting in the forest. The most direct route into the forest from Blackheath is by the Perrys Lookdown track, which descends 656 metres (2,152 ft) to the forest. The return walk uphill is rated as "hard".
  A large mountain blue gum tree measuring 65 metres (213 ft) high with a trunk 6 metres (20 ft) in circumference grows in the Blue Gum Forest. Being over 600 years old, it is a local landmark for bushwalkers. Because of the effects of trampling, camping is permitted at nearby Acacia Flat, not in the Blue Gum Forest itself.
