The Hadrian’s Wall Path is a long distance footpath in the north of England, which became the 15th National Trail in 2003. It runs for 135 km (84 mi), from Wallsend on the east coast of England to Bowness-on-Solway on the west coast. For most of its length it is close to the remains of Hadrian's Wall, the defensive wall built by the Romans on the northern border of their empire.
