Castle Rock

Castle Rock is a granite summit in Porongurup National Park that rises to about 670 meters above sea level. The mountain is surrounded by tall forests of jarrah, marri, and karri trees that create a dense natural setting.

The granite formation was originally named Alfred's Castle in honor of a 19th-century settler who helped establish transport routes across Western Australia. The peak later became known by its current name as the park developed.

The granite formations within Porongurup National Park hold significance for Indigenous Australian communities who utilized the area for traditional practices.

The hiking trail is steep and demanding, so wear sturdy shoes and bring plenty of water for the journey. Expect rough terrain and natural obstacles along the way.

Near the summit there is a metal elevated walkway with a viewing platform accessible by climbing a ladder that provides spectacular vistas. This structure was added to give visitors a safe way to reach the most dramatic viewpoints.
