Use the postcode CH7 4QR which should take you to the Rose & Crown pub in Graianrhyd.

Once you’ve found the Rose & Crown, drive past the FRONT of the pub (very large ROSE AND CROWN words on the front of the building) making sure the pub is on your RIGHT. After approx. 300m turn LEFT at the national speed limit sign / old school house (red brick building). Ignore the immediate turn right but instead drive up the steep hill on the narrow country lane. The road flattens out, you will pass two houses on your left, before reaching Llys Onnen on your right just before a farm track on your left. Name of the house is on the gate.
