Most walkers travel 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, although this can vary depending on individual fitness, attitude, the weather, age and experience. Following a man-made border and ancient monument, rather than natural features, the dyke crosses a variety of different landscapes. The route crosses the Black Mountains, the Shropshire Hills (including the many ups and downs of the 'Switchback', for many walkers the hardest part of the walk), the Eglwyseg moors north of Llangollen, and the Clwydian Range.
Various bodies on either side of the border are collaborating on a sustainable tourism partnership, a principle 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.
