Offa’s Dyke Path is a 177 mile (285 Km) long walking trail. It is named after King Offa, who ordered the dyke to be constructed in the 8th century, probably to divide his Kingdom of Mercia from rival kingdoms in what is now Wales.
The trail links Sedbury Cliffs near Chepstow, on the banks of the Severn estuary, with the coastal town of Prestatyn on the shores of the Irish sea. It passes through eight counties and crosses the border between England and Wales over 20 times. The Trail explores the tranquil Marches (as the border region is known) and passes through the Brecon Beacons National Park on the spectacular Hatterrall Ridge. In addition it links three Areas of Outstanding Natural Beauty – the Wye Valley, the Shropshire Hills and the Clwydian Range / Dee Valley.
