The mountains west of Trawsfynydd

Routes in the West

Cymmer to Conwy

From Cymmer you can follow the Roman road, Sarn Helen, much of the way to Conwy.

On the way you will visit Trawsfynydd, home of the Catholic martyr St John Roberts and the World War I poet Hedd Wyn. The Roman fort at Tomen-y-Mur is the setting for one of Wales’s oldest legends, the story of Lleu Llaw Gyffes and his magical wife, who was made from flowers.

Dolwyddelan has one of the castles of the Welsh princes and an old church with some lovely stained glass. The Roman road goes over the Miners’ Bridge and through the Gwydir Forest. Walk over the moors and down into Conwy.

There is an alternative high-level route over the mountains to Conwy then south past the Brenig reservoir and over the Clwydian range to Holywell. You can access this at

We are developing these routes. Much of it has not been checked since 2005 and it needs re-walking. We also want to extend an optional route west through Snowdonia to Aberconwy's first site near Clynnog-fawr. This would enable the Cistercian Way to link with the North Wales Pilgrim's Way alsong the north coast of the Lleyn to Aberdaron and Bardsey. For more on this route see
