Abergwyngregyn falls

Aber Falls (Welsh: Rhaeadr Fawr) is a waterfall located about two miles (3 km) south of the village of Abergwyngregyn, Gwynedd, Wales.The waterfall is formed as the Afon Goch plunges about 120 feet (37 m) over a sill of igneous rock in the foothills of the Carneddau range. Two tributaries merge; the enlarged stream is known as Afon Rhaeadr Fawr; from the road bridge, Bont Newydd ("New Bridge"), the name becomes Afon Aber.

The Anafon River, or Afon Anafon, is a river in Gwynedd, Wales, that flows into the Afon Aber.It originates on the slopes of Foel-fras and the Drum of the Carneddau. It flows into Glyn Anafon. then north-west along the Anafon Valley, flowing past monuments of the Iron Age and the Bronze Age. It joins with the Aber Estuary just above the New Bridge, the bridge over the river on the way to the back of Abergwyngregyn.
