The Offas Dyke Path National Trail, runs along the England / Wales border between Chepstow and Prestatyn, has been designed to allow some flexibility in following the official route. Alternative routes which allow visits to places of interest or to find accommodation are included and form part of the total mileage quoted. Each chapter covers what for some would be regarded as more than a full day's walk. The overall distance has been further subdivided to allow for shorter excursions, a there-and-back exploration, or to assist in planning round walks. Offa's Dyke was constructed by the powerful King of Mercia in the late eighth century to mark out the western boundary of his kingdom. The Offa's Dyke Path makes its way through varied, sometimes wild, often remote, and frequently superb scenery, linked by a succession of historic towns and attractive villages. The route offers an attractive, and at times demanding, prospect for the long-distance walker. Useful information on parking, maps required, distances and so on is all included.
