The Pennine Way is a long-distance national trail that covers 256 miles (412 km) from Edale in the Peak District National Park, Derbyshire, to Kirk Yetholm on the Scottish Border. The route passes passing through some of the wildest and most beautiful areas of the Yorkshire Dales and the Northumberland National Park, and on across into the Cheviots. At one point it follows the path of Hadrian's Wall, near Haltwhistle.
Although the Pennine Way almost exclusively follows rural trackways, it passes near to many interesting old Northern towns, villages and hamlets where walkers can find sustenance and a billet for the night.
On its path through the Dales, the Pennine Way passes near Ribblehead where you can find another equally challenging walk, the 'Three Peaks Challenge'. The challenge covers a 25 mile (40 km) circular walk over the three highest mountains in the Yorkshire Dales. The tallest peak, Wernside, rises to 2,414 ft (736 m), followed by Ingleborough at 2,375 ft (724 m) and Pen-y-Ghent at 2,273 ft (693 m). The walk starts at Horton in Ribblesdale where you can get a card stamped as proof of the challenge if you can manage it in less than 12 hours.
