Generally the Warren River Loop is a flat water Paddle – there may be intermittent logs for the first few kilometres, depending on the water level.
Portage may be difficult due to blackberry infestation. After good winter rains there will be moving water which may necessitate greater care in approaching logs, but which will make for a faster Paddle. It may be preferable to portage around whole sections with many logs – again depends on the water level and the amount of blackberries on the banks.
Starts off with karri forest, then opens out to more open woodland with some farming properties and finally the river cuts its way through sand dunes, mostly vegetated.
