What is Britain's longest National Trail footpath?

The South West Coast Path is England's longest waymarked long-distance footpath and a National Trail. It stretches for 630 miles (1,014 km), running from Minehead in Somerset, along the coasts of Devon and Cornwall, to Poole Harbour in Dorset. Since it rises and falls with every river mouth, it is also one of the more challenging trails. The total height climbed has been calculated to be 114,931 ft (35,031 m), almost four times the height of Mount Everest. It has been voted 'Britain's Best Walking route' twice by readers of the Ramblers Walk magazine, and regularly features in lists of the world's best walks.

The final section of the path was designated as a National Trail in 1978. Many of the landscapes which the South West Coast Path crosses have special status, either as a National Park or one of the Heritage Coasts. The path passes through two World Heritage Sites: the Dorset and East Devon Coast, known as the Jurassic Coast, was designated in 2001, and the Cornwall and West Devon Mining Landscape in 2007.
