The waters of the Dee flow through the sky and beneath the riverbed, they run backwards, and it is said, through Llyn Tegid without mixing, as her precious cargo surges on its way to nourish some three million people.Holy Houses line her route, many resplendent and still in use. One could have fallen from heaven itself, standing at a meeting of rivers, where a white stag guided it to be built, others are romantic ruins, while some have been lost forever.Land where there was sea, water where there was land, corpse candles, tales of UFOs and the Mabinogion await those who dip their toe in the sacred waters.Join the author as he follows Milton's wizard stream, on foot, from Talacre and Hilbre Point, through the lowlands of the borders to her source high in Snowdonia.
