Yes, the Wales Coast Path is clearly signed and waymarked with its own distinctive logo: a white dragon-tailed seashell on a blue ground surrounded by a yellow circlet bearing the words ‘Llwybr Arfordir Cymru – Wales Coast Path’.
Look for the wood or metal fingerposts at main access points, in towns, on roadsides and lanes, and at key junctions. Some show the distance to the next destination, too.
Elsewhere, the route is clearly waymarked with plastic roundels fixed to stiles, gateposts, fences and walls. In many places the Wales Coast Path waymarkers sit alongside others for already established routes — such as the Isle of Anglesey Coastal Path or the Pembrokeshire Coast Path National Trail. In some areas these local waymarkers are still more in evidence than the official Wales Coast Path ones; and on some stretches, waymarking is still patchy.
Generally, however, if you keep an eye out for the distinctive Wales Coast Path signs and waymarkers, and the sea on your right (if you’re walking from north to south), and you shouldn’t stray far from the route.
