Hadrian's Wall

Hadrian’s Wall is an 84 mile stone wall stretching from the Solway Furth near Carlisle to the mouth of the Tyne at Newcastle. Much of the two sections of the wall near Carlisle and Newcastle do not in fact have much if any wall and the walking is frankly a little dull.
However the walking in the central section (roughly 25 miles) is excellent, continually interesting and more challenging than you may anticipate.
