Launching on 1st May, the new walkers passport will enable people to record their journey in a special issue passport by collecting 12 stamps along the 177-mile trail.
The passport marks the 50th anniversary of the Offa's Dyke Association(ODA). Funds raised from the passports will be used to support ongoing conservation work.
ODA Chairman David McGlade said: “The Passport has two aims: we want it to be a great deal of fun for walkers and each one sold will help to look after the Dyke. The more Passports that we sell the more projects that we will be able to support.
We want to help Rob Dingle, the National Trail Officer, manage the Trail and Dyke sustainably and in a way that protects our heritage for this and future generations."
The passports do not have an expiry date so walkers can take as long as they like to collect the 12 stamps between May and October each year.
