Castle Rock is a 4.4km, grade 5 Return hike located in Porongurup National Park Western Australia. The hike should take approximately 1hrs to complete.


The massive ancient granite domes of Porongurup National Park rise 670 metres, giving exhilarating views of the landscape, especially from the Granite Skywalk suspended from Castle Rock.

A 4.4 kilometre (two hour) relatively steep return walk to the Granite Skywalk traverses yate, marri and karri forest and takes you past the famous Balancing Rock. Flat granite slabs offer views and places to rest. Karri Lookout is a place to ponder the Porongurup Range landscape, forests and wildlife. The Granite Skywalk is a suspended walkway that spirals around the huge granite outcrop of Castle Rock to the summit. The Skywalk has two lookouts, a lower and upper one. The upper lookout perches over the side of Castle Rock and requires scrambling over rocks and climbing a ladder. There are spectacular views of the park and across undulating farmland to Albany on the south coast, with views to Mt GaRoadner and Mt Manypeaks to the south-east. This remote engineering marvel provides safe access and simulates a rock climbing perspective when suspended on ropes. To view a video of the walk and lookouts click here.
