This hike is classified as Grade 4 (Hard) due to its significant distance exceeding 20km. While the terrain itself is relatively easy and may be suitable for all abilities, the long distance requires a good level of fitness and preparation. Feel free to turn back at any point for a shorter adventure.
The 22 kilometre, Old Timberline Trail, located near Nannup, south of Perth, Western Australia, is a two day walk or one day cycle with an overnight hut on the bend of St John Brook. This scenic trail ranges from windy walk trail to old timber roads.
Originally a road and rail line used to remove logs from the jarrah forest, today the trail is utilised by walkers and mountain bike riders. Unlike other rail trails it is hilly in sections and becomes narrow in many places, proving challenging, but very scenic. The trail features interpretation on the old timberline heritage, beautiful flora and fauna and spectacular views to the bends in St John Brook from Sleeper Hewer's Camp. Beginning at either end, the trail runs from the rail bridge (over the Blackwood River) in Nannup to Cambray Siding - the intersection of the Sidings Rail Trail (combine these two trails for a 37 kilometre ride). The Old Timberline Trail follows St John Brook Creek and passes many beautiful locations. Sleeper Hewers Camp, sleeping a maximum of 8 people, is situated near one of these settings. Other car access points to the trail are from Barrabup Pool and Workman's Pool (where there are swimming holes, toilets and Picnic Areas) and Cambray Siding (the road into Cambray is narrow and may not be passable by 2WD vehicles after wet weather). Workman's Pool also has facilities for car camping. A second rail trail, the Sidings Rail Trail, also begins at Nannup and follows the route of a former government railway. The two trails can be combined to form a 37km loop. The Department of Environment and Conservation's "Sidings Rail Trail" brochure includes details and a map of both trails and is available to purchase for around $5 from the Department

Situated on the banks of the Blackwood River and nestled in the Blackwood River Valley, Nannup has been perfectly preserved as a historic and character-filled timber town from the early 1900s. As a result, it was chosen as a film location in the 1970s-inspired surf movie Drift. Bullnose verandas, weatherboard shop fronts and colourful flower boxes all enhance the delightful appeal of the town and keep it in character, surrounded by trees it exudes peace and calm. A walk along Nannup's main street will take you past tearooms and gift stores full of local wares.
