Starting from the car park at the end of Brockman Street, Nannup, this walk takes you along a disused tramway formation to Cambray Siding via the Old Timberline Rail Trail. The trail begins at Nannup Foreshore Park and follows the route of the Kauri Timber Company's old tramway, passing through St John Brook Conservation Park for much of its length. After crossing the railway bridge over the Blackwood River, the trail heads southwest to join the tramway formation, then passes by spectacular swimming holes and excellent campsites as it winds its way through stands of mature jarrah forest and along the banks of St Johns Brook. Signs explaining the history of the railway and tramway are scattered along the route between Barrabup Pool and Cambray Siding. Suitable for walking and cycling, the trail is mainly compacted earth and gravel, with some narrow and steep sections where it leaves the tramway formation. Camping is available at multiple points, including an overnight option. There are also several points with vehicle access, so you can choose to walk or ride a shorter section. The area is best visited in late winter or early spring when the wildflowers are blooming and the pools are full after the winter rains. We acknowledge the Noongar people, the traditional custodians of the land and waterways on which the rail trail is built. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
