Greening the Great West Walk

About the Great West Walk

The Great West Walk is a 65-kilometre urban trail that stretches from Parramatta Park to the base of the Blue Mountains on the lands of the Darug nation. The walk is located on land in the Parramatta, Blacktown and Penrith local government areas.

Mapped by The Walking Volunteers – a group of experienced walkers creating a network of significant walking routes in Sydney – the Great West Walk was opened by the NSW Minister for Planning and Public Spaces in October 2019.

Throughout 2021–22, the department and our partners are Greening the Great West Walk. More than 26,000 trees will be planted to provide shade, beauty and cooler temperatures. This will make the Great West Walk more comfortable, accessible and enjoyable for users, local communities and visitors to Western Sydney.

Feasibility study

In May 2020, the department commissioned Gallagher Studio, to identify and prioritise potential tree-planting locations along the Great West Walk.

The process involved:

  • mapping, research, analysis, and consultation
  • examining the walk, in relation to its environmental, climatic, and social context.

The research revealed large portions of the walk have very low tree canopy cover (less than 20%) making parts of the walk 8-11 degrees warmer than other parts of Sydney.

The feasibility study has helped inform the selection of final tree-planting sites and projects to green the Great West Walk.

Increasing canopy cover along the walk

We have partnered with Blacktown, Penrith and Parramatta councils, Greening Australia and Landcare NSW, to plant more than 26,000 trees along the walk, making Western Sydney a cooler and greener place for local residents and everyone to enjoy all year around.

Planting will occur at six tree planting locations to help:

  • increase urban tree canopy and green cover through innovative planting practices
  • reduce temperatures along the Great West Walk and mitigate the urban heat island effect
  • improve walkability and accessibility for all users of the walk
  • enhance biodiversity and restore local ecology.
