No dogs allowed

We set out N. on the well-established N. Wales path, before ascending to the top of the first hill, Graig Fawr. From there we head SE on Offa’s Dyke path towards Marian Mill, where we start to climb up Marian Ffrith. The route climbs further S. on the flanks of Mynydd y Cwm. This forested Marilyn summit, is not on public access land, so we head W. just below the tree-covered peak before we turn NW, towards Y Foel, passing Cwm and the Blue Lion pub. We return to Dyserth and take rights of way N. of Bryn y Felin back to the car park

Sections of N Wales and Offa’s Dyke paths, fields, forest paths and short sections on lanes and pavement.
