Oxford Road, Hay-on-Wye - 01497 820144 post@hay-on-wye.co.uk

The town lies on the south-east bank of the River Wye and is within the north-easternmost tip of the Brecon Beacons National Park, just north of the Black Mountains. The town is just on the Welsh side of the border with Herefordshire, England, here defined by the Dulas Brook. I have included it in Herefordshire because most people who visit come from the English side and regard it as English. The phone and psot codes are all English. Where the brook joins the River Wye just north of the town, the border continues northwards along the river. The Wye was the boundary between the former counties and districts of Radnorshire and Brecknockshire.

The adjacent village of Cusop lies on the English side of the Dulas Brook. The nearest city is Hereford, county town of Herefordshire, some 22 miles (35 km) to the east.

The Royal Mail depot in Hay is a sub-office of Hereford, England and has the HR3 postcode.
