If you're coming from the Ruabon direction look out for the former Air Products Works on your left (now a cleared site with a security metal fence) about ½ mile past the Plas Madoc Estate entrance. At the next junction note the "Eagles" public house on your left. Take the next turn to the right just before a group of 3 single storey shops (a Barber, a Hairdresser and a Vet) and this will bring you into Acrefair School.
If you are coming from the direction of Llangollen, pass the "Aussie Rooster" public house. Pass the "Duke of Wellington" public house on the left, the entrance to the old "Flexsys Ruabon Works" on the right (now signposted to parking for the Pontcysyllte Aqueduct). Continue up the hill and after about 250 yards you will see a small car park and a group of 3 single storey shops on your left (a Barber, a Hairdresser and a Vet). Turn left immediately after those shops and this will bring you into Acrefair School.
If you are using a "SatNav" the postcode is LL14 3SH.
