Porongurup National Park, Nature reserve in Great Southern region, Australia

Porongurup National Park protects the Porongurup Range, a 15-kilometre east-west line of porphyritic granite domes rising to Devils Slide at 670 metres. Castle Rock, at 558 metres, carries the Granite Skywalk, a steel viewing platform above the surrounding karri forest. Karri grows on the upper slopes in red karri loam, while jarrah and marri forest covers the lateritic soils below.

The Porongurup Range was first sighted by Europeans passing near Albany in 1802, and vegetables were grown on its southern slopes from around 1859. Karri and jarrah timber was harvested from the 1880s, with timber leases withdrawn from 1925. The national park was officially gazetted only in 1971, initially covering 1,157 hectares, later increased to 2,511 hectares.

The Mineng and Koreng peoples of the Noongar community call this area Borrongup, reflecting their deep connection to the land. You can walk the marked trails and experience the cultural importance of the landscape as you move through it.

The terrain requires appropriate footwear and water supplies, especially on longer walks during warmer months. Visitors should arrive early to secure parking and have adequate time to explore the different trail options at a comfortable pace.

The park hosts more than 700 native plant species, with nine found nowhere else in the world beyond this location. Rare birds like Baudin's black cockatoo also call this area home, making it a critical refuge for threatened wildlife.
