The route
This verified circuit leaves Rhayader for the Elan Valley reservoirs and Cwmystwyth mountain road, continues to Aberystwyth and Strata Florida, then returns inland. The inherited Devil's Staircase label has been corrected.
Narrow roads, livestock, cyclists and changing weather demand conservative speeds. Services are limited away from the coast.
April to October offers useful daylight. Check Traffic Wales and Elan Valley guidance before departure.
