Hike overview
Starting at the Bicentennial Tree, an old bushfire lookout, the 10.5 kilometre Warren River Loop Walk wanders down through tall karri forest to the meandering Warren River, where you can enjoy a swim before heading up to the Warren lookout for superb views into the valley.
The Bicentennial Tree is one of three firelookout trees open to the public in the Pemberton/Manjimup area. It is 75m 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. The beautiful karri forest is home to many different varieties of Birds including red capped parrots, blue wrens, robins, honeyeaters, silvereyes and crows. 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 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. Other trail access points exist at the information shelter at Heartbreak Trail, Maiden Bush Car Park, Drafty's Camp, Warren Camp and Warren Lookout. Local FM radio has indigenous stories from the area, broadcasting throughout the day. Whilst in the area try the many other walks and trails including the 200 metre Lorikeet Stroll.
