Afon Dwyryd, Rivers Talsarnau, Gwynedd - Wales where to go, what to see and where to stay in Wales

The Afon Dwyryd rises in the Moelwyn hills to the north of Ffestiniog. The waters form the Tanygrisiau Reservoir. The Afon Goedol flows from the Tanygrisiau Reservoir. This is joined by the Afon Bowydd and the river is then joined by the Afon Cynfal. The main river from here on flows through the Vale of Ffestiniog and is then joined by the tributaries Afon Tafarn-Helyg and the Afon Prysor before being joined by the Afon y Glyn near the Dwyryd estuary salt marshes. The Dwyryd flows past the village of Portmeirion before the confluence of the Afon Glaslyn and then draining into the sea at Tremadog Bay.
