Offa’s Dyke is a great frontier earthwork built by Offa, King of Mercia from 757 to 796 A.D. It gives its name to a long distance footpath, one of Britain’s National Trails, which runs for 177 miles from Sedbury, near Chepstow, to Prestatyn through the varied and little-frequented landscapes of the Welsh Marches.

The Offa’s Dyke Association was set up in 1969 to provide a link between walkers, historians and conservationists and those who live and work locally. All persons and organisations interested in the Welsh Border region are invited to join. Full membership is £20 individual and £25 joint / family a year.

The Association is an active member of the Offa’s Dyke Collaboratory  and we encourage anyone with  more than a passing interest in the monument to consider registering with the Collaboratory, which costs nothing.

To contact the Offa’s Dyke Path National Trail Officer, for example to report problems with gates, stiles or signs, email: or write to Rob Dingle, Powys County Council, The Gwalia, Ithon Road, Llandrindod Wells, Powys. LD1 6AA Tel. 01597 827580

Chepstow, at the southern end of the National Trail is a warm and friendly ‘Walkers are Welcome‘ town. Volunteer  groups help to keep the Trail and wider footpath network neat and tidy and the Chepstow WAW Walking festival is now firmly established in the calendar. 

There are active heritage and amenity groups the length of Offa’s Dyke Path. Old Oswestry Hillfort in north Shropshire, which incorporates the much later Saxon Wat’s Dyke, is only a stone’s-throw from the National Trail and is itself looked after by an active volunteer group under the auspices of Historic England. 

Another very active group, again in north Shropshire, is the Trefonen Heritage Protection Group. In October 2017 an audience of 120+ turned up to listen to an expert talk on Offa and his Dyke by Dr Keith Ray. 

The Radnorshire Society, established in 1930, is concerned with the archaeology and history of the historic county of Radnorshire (now part of Powys).  An almost complete set of  The Transactions of the Radnorshire Society can be viewed in the Frank Noble Library in the Offa’s Dyke Centre.

The Saxon capital of Mercia, Tamworth, is today championed by the Tamworth Heritage Trust

The South West Coast Path Association

The South West Way Coastal Path is Britain’s longest National Trail – over 600 miles! It starts at Minehead in Somerset and goes right round the South West Peninsula as far as Poole Harbour in Dorset. It has part of the Somerset coast, the North Devon coast, all Cornwall, the South Devon coast, and nearly all of the Dorset coast.

The South West Way Association was formed in 1973 with help from the ODA, and is now known as The South West Coast Path Association. Plenty of information is available about the coast path for those who wish to walk all, or indeed part, of it. An Annual Guide Gives a full trail description, comprehensive accommodation, ferries, local transport, and other useful information. A series of 50 detailed path descriptions are also available.

In recent years we feel substantial progress has been made in improvements to the route and in the general standard of maintenance. This is not to say that further work has not to be done. The more people that can support the Association, the sooner there will be a path that can give more enjoyment to a greater number of people.

Therefore, the Association both offers information and asks for your support. Please send enquiries about membership and purchase of the Annual Guide to the Administrator, Kate Holland, South West Coast Path Association, Bowker House, Lee Mill Bridge, Ivybridge, Devon, PL21 9EF ( phone 01752 896237), email or web site
