The Porongurup Range, located in WA's Great Southern region, is an internationally recognised biodiversity hotspot. The ancient granite range supports over 700 native plant species, including 10 endemic species. The diverse vegetation types provides habitat for a wide range of native animals, including several endangered and vulnerable species. 

The unique climate and elevations create a damp, protected environment that sustains a rich mix of towering forests and colorful shrublands. The upper slopes feature magnificent stands of towering Karri forest, an outlier from the main deep-south karri belt. The lower slopes are cloaked in open Jarrah, Marri and Yate woodlands. Spring (August to November) brings the forest floor and shrublands to life with over 55 species of orchids (including the Purple Enamel and Cowslip orchids), mountain bells, flame peas, and banksias. Over 300 macro-fungi species have been identified, making it an incredible destination for fungi enthusiasts.

Porongurup National Park is home to a rich array of wildlife, and visitors can frequently spot Western Grey Kangaroos, Brush Wallabies, and Brushtail Possums. The range is also home to nocturnal marsupials like honey possums, pygmy possums, and quendas. Over 80 bird species have been recorded here. Look out for the Rufous Treecreeper, Scarlet Robins, and Western Yellow Robins. The old-growth trees provide crucial nesting hollows for threatened black cockatoos, including the Carnaby's, Baudin's, and Forest Red-tailed Black Cockatoo. The damp forest floor and moist gullies harbor various skinks, goannas, carpet pythons, and ground frogs.

This is a challenging but amazing hike with epic views. Not recommended when its wet as the trail often turns into a river.

A very enjoyable walk. Challenging at times.

Made the climb in January 2018 after traversing a few other trails in the Porongurups.
Great climb and spectacular views from the summit.
The hike back down proved challenging for my knees and I'm still paying the price four months later.
Definitely worth the effort, but take your poles!
