Starting at the Bicentennial Tree, an old bushfire lookout, the moderate 10.5 kilometre Warren River Loop Walk wanders down through tall karri forest to the meandering Warren River before heading up to the Warren lookout. This Top Trail is close to the historic timber town of Pemberton, 343 kilometres south of Perth.
The Bicentennial Tree is one of three fire lookout trees open to the public in the Pemberton/Manjimup area. It is 75 metres tall and provides an exciting challenge for those brave enough to climb to the top!
From there, the trail travels through the tall timber to another picnic area. Generally it is downhill to the river, although some of the inclines are quite steep and require a moderate degree of fitness. Arriving at the river there are camping areas and platforms to allow swimming access.
After following a narrow path for a few kilometres along the river, there is a steady climb up to the spectacular Warren River Lookout.
This half day walk has a fine blend of large karri trees, quality forest, river bank walking and views into the valley; with interpretive sites along the way.
