The main route from Conwy to Basingwerk follows the North Wales Pilgrim's Way through St Asaph and over the foothills of the Clwydian Range to Holywell and Basingwerk.
Holywell is the ‘Welsh Lourdes’, one of the ‘Seven Wonders of Wales’. Here St Winifred was beheaded by a disappointed suitor. The well sprang up where her head fell. She was healed by her uncle St Beuno and went on to become a great religious leader.
There is also an alternative high-level route over the Hiraethog Moors, past the Brenig reservoir and archaeological trail — see http://www.cistercianway.wales/directory/high-level-alternative-cymmer-basingwerk
Part of it is on old hollow ways and part goes over rough open moorland with wonderful views but no obvious trackway. You need to take a detailed map and compass and know how to use them — but you will be rewarded by an exhilarating day’s walking.
