Location and catchment area

The average annual rainfall in the catchment of the Llugwy is the highest recorded in England and Wales. The Llugwy largely follows the route of the A5, passing firstly through the village of Capel Curig, then on to fall over the Swallow Falls, a popular tourist attraction. On entering Betws-y-Coed it is crossed by the Miner's Bridge, a curious wooden bridge set at a steep incline over the river, and shortly after passing under Pont-y-pair road bridge it flows beside the main street before its confluence with the Conwy at the far end of the golf course.
