Hard track
Starting from the Nanga Mill Campground off Nanga Road, Nanga Brook, this walk takes you on a circuit through the Murray River Valley via Murray Valley Road, North Junction Form, King Jarrah Form and the King Jarrah Walk Trail. The King Jarrah Circuit is an enjoyable trail within Lane Poole Reserve, through a mixture of jarrah and banksia dominated forest. The highlight of this walk is the 'King Jarrah', a 300-600 year old jarrah tree standing 47 metres tall, with a diameter of almost 2.7 metres. From Nanga Mill, the trail heads clockwise on Murray Valley Road, keeping to the Murray River as it weaves south down North Junction Form through the imposing forest of jarrahs, the King's younger relatives. Look up for birds flitting through the treetops and look down for the fungi growing brightly on the tree trunks and forest floor. The trail veers right at Big Brook, leading onto King Jarrah Form, the final stretch before a steep ascent to the ancient and iconic King Jarrah tree. The walk continues along the ridge offering good views of the valley below before descending steeply back to the campground. The track is best suited to moderately experienced walkers, with a long distance to be covered and some steep ascents and descents. There's plenty of signage along the way, and facilities at Nanga Mill include a car park, toilets and camping areas. Dogs are allowed, as long as they're kept on a leash. If you'd prefer to tackle the tougher climb section of the circuit walk first, head anti-clockwise from the start point at Nanga Mill. 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.
