At the end of each stage you will find one of these signs where you can scan a QR code, which will show you have completed that section of the Walk.
Your digital passport will be automatically stamped. QR code locations may be in the window of a nearby museum, shop, hotel or B&B, or on a church or village noticeboard.
All the locations are detailed in the route description and marked on the route map here.
There are 17 stamps to collect in total and you will need at least 12 to claim your badge and certificate.
There is no mobile phone coverage at the Rhyd-y-benwch (start/end of the walk), so take a photo of yourselves and upload it to claim your stamp for that stage of the walk.
