The Ridgeway is an ancient, pre-Saxon, pre-Roman, even pre-Celtic track of more than a hundred miles through the English countryside near Stonehenge and Avebury. It has never been plowed over and runs past many ancient sites, including ringforts, Wayland's Smithy, and the White Horse of Uffington. Even though it is in one of the most overcrowded areas of Europe, it is a lonely, beautiful place to walk.
