This walking guide covers both the Cumbrian and Durham sides of the North Pennines, a designated Area of Outstanding Beauty, and also extends eastwards across Durham to the North Sea Coast.The area contains some of the finest moorland in the country, explored here in walks across Bowes Moor and the grouse moors near Holwick, but there are also plenty of relaxing, low-level walks beside rivers, through woodlands and forests, by the coast, and along former railway tracks.Durham Castle and Cathedral, Brough Castle, High Force the mightiest of England's waterfalls, and Causey Arch, the world's earliest railway bridge, are featured.
