The River Cynon (Welsh: Afon Cynon) in South Wales is a main tributary of the Taff. Its source is the rising of Llygad Cynon (OS grid ref SN 95240 07740) at 219 m (719 ft) above sea level at Penderyn, Rhondda Cynon Taf and flows roughly southeast, into the Taff at Abercynon in the same district.[1] The water emerging at Llygad Cynon has been traced back to the sink of the Nant Cadlan at Ogof Fawr.[2]
