Cyfyng Falls (on the Afon Llugwy) are relatively unknown, although they are situated along the main road between Betwys y Coed and Capel Curig. The falls are directly below the road and can be seen from the Pont Cyfyng bridge. After the bridge turn right onto a lane/footpath which branches off to the right just after a gate. Follow this to the river for a better view. It is not the height that makes this waterfall so attractive, but the power of the water and the landscape.

Pont Cyfyng is a bridge over the River Llugwy at Capel Curig. The river flows very fast here, with rapids and waterfalls. Beautiful to see.
