The River Lledr is in North Wales and a tributary of the River Conwy. The Lledr has its source on the eastern slopes of Ysgafell Wen, which lies between Moel Siabod and Cnicht. It flows north-easterly towards Blaenau Dolwyddelan, where Ceunant Ty'n y Ddol joins it, then flows under the Roman Bridge and past the village of Dolwyddelan, where Afon Penamnen joins it. It continues to the north-east past Pont-y-Pant, where it can become a raging torrent, and then east along the Lledr Valley, it then joins the River Conwy to the south of Betws-y-Coed.
