Llyn Idwal is a small glacial lake in Snowdonia, easily accessible from the A5. The path begins at Ogwen Cottage at the foot of Llyn Ogwen, crosses a stream and then turns right after a quarter of a mile in to Cwm Idwal, a dramatic valley surrounded by the crags of Glyder fawr, Twll Du (‘The Black Hole’ or more popularly known as ‘the Devils Kitchen’) and Y Garn.
