From Trevor we took the Offa's Dyke Path (ODP) W and left it to climb to the ruins of Castell Dinas Bran. A footpath leads S to Llangollen and the road across the Dee. A path climbs S from 212418 and becomes a track heading W to the head of the Nant y Bache then descends SE around Y Foel to the lane at 187384. Turning R it terminates at a car park where we walked N a short way to collect water from the stream just above and L of the old mine pool. Returning to the lane end we took the track SW to Blaen-y-cwm then W to Dolydd Ceiriog where a shooters track heads N to a T junction and L to Bwlch Cynwyd. A mown track climbs N through the heather to Moel Fferna.

From the fence SE of the summit a good path leads E to the forest corner and then the main entrance at 148393. Taking the second main track L (155387) it leads out of the forest near the SE corner at the lane. We followed the lane E, with good views over the vale in the latter stages, to Fron Uchaf 271405 where we descended SE & E to join the ODP along the canal to Trevor. The ODP passes along the Thomas Telford aqueduct high above the river and generates a surprising feeling of exposure. This is a popular spot and there was a team of canoeists on the aqueduct, as well as tourists gingerly shuffling past and trying not to be knocked in (or over!) by our packs.
