With an elevation of 670m Devils Slide is the Porongurup Range's highest peak. It provides magnificent views over the granite domes of the Porongurup Ranges. Known for its high flora species diversity, the ranges are home to over 700 plant species, including 10 endemic species. You may even be lucky to spot one of the many mammal or bird species, honey possums, brushtail wallabies and even rare bird species of Baudin's cockatoo and noisy scrub-birds.

Spend the morning walking to Devils Slide then return to Karri boya-k (Tree in the Rock) picnic area to enjoy the picnic and barbecue facilities. For the more adventurous walkers, Marmabup Rock can be reached a further kilometre on from Devil's Slide on the same path continuing West.

The walk can be completed in many different ways. The direct route along the Wansbrough Walk, after which 1600 meters you turn right to the Devil's Slide trail for a further kilometre. On your return, you can follow the Wansbrough Walk trail back to the picnic area or you can return via the Hayward and Nancy Peak Walk. It is a 4-kilometre steady climb through undulating peaks back to the picnic area. A trail which will take you to the lookouts of both Nancy Peak, Morgan's Peak and Hayward Peak for more spectacular sweeping views.

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!
