The western end of the Blue Mountains has some great walks.
(see my gallery https://pbase.com/barry_2718/bushrangerscave )
One tree hill lookout is also the highest point in the Blue mountain's
closely followed by nearby Mount Piddington.
These lesser known lookout provides an excellent view when there
is no smoke. It is not far from Mt Victoria, but most people drive
right past it without realising it beauty.
