The occasional muddy soil should not stop you from visiting the long-distance footpath of Hadrian's Wall Path. The National Trial—a classification gained in 2003—stretches for 84 miles from east to west in the north of England.

Near the footpath lie the remains of the Roman fortification, Hadrian's Wall. The wall was built under the orders of Emperor Hadrian after the Roman conquest of Britain. Despite a common belief, it has never served as the border connecting England and Scotland. Originally, the wall covered more than 70 miles of the northern English countryside between the River Tyne and the North Sea. Recorded as a British cultural icon and a UNESCO World Heritage Site, it is the largest Roman archaeological display in Britain.
