After 2 miles, road goes down into a valley, past parish sign of St.Levan. Take 1st left (very steep turn) signed to Penberth. After 1/4 mile Chmoy Mill is on the left, just before two granite terraced houses which are set back from the lane on the right. If you arrive at the granite archway over the river on the left, you have gone too far.
