Llyn Idwal is a small lake (approximately 800 m by 300 m, or 28 acres) that lies within Cwm Idwal in the Glyderau mountains of Snowdonia.[2]
It is named after Prince Idwal Foel, a grandson of Rhodri Mawr, one of the ancient Kings of Wales. Legend states that the king's unfortunate offspring was murdered by being drowned in the lake. In fact Idwal Foel died in battle against the Saxons in 942 and an alternate version claims that he was cremated beside the lake, as was the burial custom for Celtic nobility. [3]
A number of small streams flow into Llyn Idwal from around Cwm Idwal. One small river flows out and joins the Afon Ogwen river at Pont Pen-y-Benglog near Ogwen Cottage, immediately above the Rhaeadr Ogwen waterfall.
