I explore the hidden landscapes, ancient geology and surprising stories that appear when you look more closely at this remarkable corner of Britain. I reveal how glaciers shaped valleys, how sea fossils reached the summit of Snowdon, and how Welsh slate once roofed much of the world. I also visit the abandoned quarries, the power station hidden inside a mountain, the Welsh gold belt, the drowned village of Capel Celyn, and the unique Gwyniad fish of Bala Lake. From Bronze Age copper tunnels beneath the Great Orme to Harlech Castle’s vanished shoreline and a village name created to attract railway travellers, these facts show why North Wales is much more than a familiar holiday landscape. After decades teaching geography, I share the details that many people drive past without ever noticing.
