Starting at the Nannup Foreshore Park, the 22-kilometre Old Timberline Trail runs north towards Jarrahwood. The heritage walk and cycle trail follows the path of a historic Kauri Timber Company line.
The Old Timberline Trail is a Class 2 walking trail and Easy mountain bike trail. The trail meanders through some lovely forest along the banks of the St Johns Brook and the ruins of a 100-year old once-spectacular railway bridge. The trail passes by Workmans Pool and Barrabup Pool, offering an opportunity to dip in the cool water and a blissful relief in the warmer weather.
Join the Sidings Rail Trail at Cambray Road, south of Cambray Siding, to complete the Timberline Loop (48 kilometres). Otherwise backtrack to Nannup Foreshore Park or arrange a lift at Cambray Road (4WD recommended).
There are several vehicle access points along the trail where you can choose to walk or ride a shorter section if desired. Some of these access points are via unsealed road and may be suited to 4WD only.

Fayley Arthur rated Old Timberline Trail, Nannup a 4 out of 5
Perfect trail for a beginner overnight bike-packing adventure. If you combine the Old Timberline trail and the Cambray Siding/Sidings Trail and make a round trip returning to Nannup, you can stay overnight at the (free) campground at the historic Sleeper Hewer's Hut.
This campsite is less than half way around the circuit, so it allows you travelling time down to Nannup on the morning of your trip - perfect! The campsite has a "pool" in the St John's Brook, so you can have a dip or quick plunge at the end of the day. The trail has some rocky and steep descents which will have beginners walking their bikes, but the forest is absolutely beautiful and healthy.
