This is a book containing the walk A. Wainwright devised in 1973, covering rights of way and areas of open access between the Irish sea and the North Sea. The route passes through three National Parks: the Lake District, the Yorkshire Dales and the North York Moors, all areas of outstanding beauty. The book provides a wide and varied range of scenery with changing landscapes over a distance of 190 miles. It is one of the most challenging of long-distance walks.
