Traveling south to north, starting by the Severn Estuary at Sedbury, near Chepstow, and finishing at Prestatyn on the north coast, the walk will take an average walker roughly 12 days to complete.^[2] Roughly following the border in parts, and elsewhere the ancient monument of Offa's Dyke, as well as natural features such as the Hatterrall Ridge, the Dyke Path passes through a variety of landscapes. The route traces the eastern edge of the Black Mountains, traverses Clun Forest, the Eglwyseg moors north of Llangollen and the Clwydian Range.

The route passes through the counties of Monmouthshire, Gloucestershire, Powys, Herefordshire, Shropshire, Wrexham, Denbighshire and Flintshire. The Welsh Marches (Marchia Wallie) is a term used to describe this border region between England and Wales, since it was recorded in the Domesday Book in 1086.^[3][4] It passes through, or close to, the towns of Chepstow, Monmouth, Hay-on-Wye, Kington, Presteigne, Knighton, Montgomery, Welshpool and Oswestry, then in and around the North Wales towns and villages of Llangollen, Llandegla, Bodfari and Dyserth.

The half-way point of the path is marked by the Offa's Dyke Centre in Knighton (52°20′45″N 3°03′06″W / 52.3458°N 3.0517°W / 52.3458; -3.0517 (Offa's Dyke Centre)).^[5] There used to be around 600 stiles along the route, but many of these have now been replaced by kissing gates.

a certain vigorous king called Offa......had a great dyke built between Wales and Mercia from sea to sea.

Various bodies on either side of the border are collaborating on a sustainable tourism partnership, a principal focus of which is Walking with Offa, both on the trail but also in what has been dubbed Offa's Country i.e. in a corridor along the border.^[7]

The path was the focus of an episode of the Channel 4 program Britain's Ancient Tracks with Tony Robinson.

In June 2021, during the footpath's 50th year, an Offa's Dyke Rescue Fund was launched to restore eroded and other damaged parts of the route and to buy parts of the path at risk of sustained damage or negligence from local land owners. The fund is working in consultation with Cadw and English Heritage and the National Trail Unit.^[8]

On 22 August 2021 BBC's Countryfile programme celebrated 50 years of the path.^[9]
