Experience the impressive 250 year old King Jarrah Tree as you loop through the Jarrah Forest and admire views of the Murray River on the King Jarrah Hiking Experience. The King Jarrah trail traces the former transportation routes of the once vibrant timber industry. The much prized hard woods of jarrah, marri and blackbutt saw a proliferation of timber towns in the late nineteenth century and were an important source of employment for the early pioneers.
