The Afon Rhondda is a characterful river flowing through the heart of the Rhondda Valley in South Wales, United Kingdom. Fed by the upland hills and moorlands of the South Wales coalfield plateau, this freestone river drains a dramatic valley landscape shaped by both industrial history and natural beauty. The river has two major tributaries — the Rhondda Fawr and the Rhondda Fach — which together form a system offering over 10 miles of accessible fishing water. The Rhondda Fach has its source close to the Rhondda Fawr on the hills above Blaenrhondda, flowing first through the Lluestwen reservoir before descending through Maerdy, Ferndale, Tylorstown, and Ynyshir before joining the Rhondda Fawr at Porth. The river runs through a classic Welsh valley setting, with the character of a typical upland freestone stream — responsive to rainfall, with riffles, runs, and pools that provide varied habitat for wild and stocked fish alike.
