Starting from the Dave Evans Bicentennial Tree off Old Vasse Road, Yeagarup, this walk takes you on a circuit deep into the Warren River Valley and alongside the Warren River via the Warren River Loop Trail. This moderately hard walk trail passes through some of the region's most magnificent old-growth karri forest, towering over an enchanting world of lush undergrowth, wildflowers and colourful fungi. The first section is a great introduction to the karri forest, with a wide trail snaking its way through the landscape, allowing you to soak in the sights and sounds of the forest. The gentle, rolling hills allow you to ease into the hike before the trail descends steeply towards the river. A narrow trail follows the river for a few kilometres before the steady climb to the spectacular Warren River Lookout on the way back to the Bicentennial Tree. Going through the karri forest and meandering along the river, you'll feel a sense of peace on this walk. The trail is steep in places as it climbs in and out of the river valley, although the river section is mostly flat. The trailhead is very informative, and the trail is well marked with trail markers and maps along the way. Walk in the anti-clockwise direction if you don't want to walk up the steepest part. Be sure to wear appropriate footwear and carry plenty of drinking water. 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.
