Castle Rock, Western Australia

Castle Rock is a tourist attraction in the Porongurup Range in the Great Southern region of Western Australia and is renowned for its fauna and flora.

There is a walk trail to the summit which offers 360 degree views, 570 m above sea level from a lookout known as the Granite Skywalk. The walk also takes in the unusual 'Balancing Rock', a 6 m granite boulder which reportedly weighs around 186 t yet rests on a base just 1.21 m2.

A winery located on the eastern slopes of the range is named after this landmark.
