Coming from the aramara end the mill is on the right, eastern side, of Agnes Vale.
The road /track runs past it and turns north back toward Agnes Vale rd. Plenty of ups and downs thru creek lines.
Not very long 5-6k from memory but a good fun drive in the wet.
The brooweena turn is back in the scrub well before Agnes Vale. Last time I was in that far even the bridge bypasses were gone. Just holes 3m deep.
Keen to do it again when New Pig is all good to go.
