About the region
The massive ancient granite domes of Porongurup National Park rise 670 metres, giving exhilarating views of the landscape, especially from the Granite Skywalk suspended on Castle Rock. Porongurup Range is a fascinating place for picnicking and bush rambles. It is a place of incredible biodiversity, with 750 native plant species in an area of just 2600 hectares. Paths lead to several peaks, other paths cross the range, and a nature trail leads through the forest near the Tree-in-the-Rock picnic area. The Castle Rock picnic area is another great picnic spot and also the start of a 4.4 km return walk to the Granite Skywalk with its incredible views.
