Refuge Rock is a large area of rock outcrops and platforms, at the end of the Refuge Rock walk near Cherrybrook. This area has a great atmosphere and is a nice spot to explore or relax, close to the suburbs, but feeling a million miles from it. The various rock platforms extend for hundreds of metres in all directions. At the far south-east edge of Refuge Rock is a natural arch, know as 'London Bridge'. Refuge Rock was used as a target area during military training around WWII. There are a number of visible marks in the rock surface from mortar shells.
