A great ride out alongside the Lefroy Brook on the old tourist drive - Rainbow Trail. The trail goes out to Big Brook Dam and utilises old fire roads, tracks and the Big Brook Dam trail. Stunning Karri trees, a swim at Big Brook Dam or a picnic with vehicle access for those who would like to meet you along the way.

Using the Rainbow Trail now a multi use trail (walkers, horses and mountain bikers) and a shared section with the Bibbulmun Track on the way out and on the return.
Commence the ride at the Pemberton Mountain Bike Park trail head.
As you head out the trail follows the Lefroy Brook with water cascading over small rapids along its way towards the Warren River.

The ride utilizes gravel roads, fire trails and single track. There maybe sticks, the odd tree limb and logs and some water erosion on the gravel roads and tracks.
Note: There maybe vehicles due to people accessing the river for fishing, Water Corporation workers accessing the Pemberton Weir and the one farmhouse located off Rainbow Trail.
