The River Conwy ... Afon Conwy is a river in North Wales. From its source to its discharge in Conwy Bay it is a little over 27 miles (43 km) long. "Conwy" was formerly Anglicised as "Conway."
It rises on the Migneint moor where a number of small streams flow into Llyn Conwy, then flows in a generally northern direction, being joined by the tributaries of the rivers Machno and Lledr before reaching Betws-y-Coed, where it is also joined by the River Llugwy. From Betws-y-coed the river continues to flow north through Llanrwst, Trefriw where it is joined by the Afon Crafnant and Dolgarrog where it is joined by Afon Porth-llwyd and Afon Ddu before reaching Conwy Bay at Conwy. During spring tides the river is tidal as far as Tan-lan, near Llanrwst.
