River Conwy

The River Conwy 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." The name 'Conwy' derives from the old Welsh words 'cyn' (chief) and 'gwy' (water), the river being originally called the 'Cynwy'. It rises on the Migneint moor where a number of small streams  flow into the Llyn Conwy Reservoir, 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 Afon 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
