The Gwastedyn Church Trail in the county of Powys in Wales is an established pilgrimage route which begins in Rhayader and is almost a circular route, ending in Cwmdeuddwr which is less than one mile from the start. The trail links seven historic churches and uses mountain paths, established lanes, roadways and disused railway lines to do so. The terrain of the walk is a superb mix of mountain, lake and river country including parts of the Elan Valley. Following the trail is a history lesson of the region as the walk visits sites of Celtic Saints, the Romans and Romano British, the Normans, the Welsh princes, Medieval Monks, Romantic Poets, the Victorian era including the industrial revolution and up to present day developments. From Rhayader the route visits Elan Village, the Elan Valley, Caban-coch and Garreg-ddu Reservoirs, Wye Valley, St Harmon, Nantmel, Nantglas and Llanwrthwl.
Note: The Gwastedyn Church Trail was created by Richard Tyler of Llandrindod Wells.
