The Offa’s Dyke Path National Trail criss-crosses back and forth along the Anglo-Welsh border, stretching from North to South Wales, passing through no less than three Areas of Outstanding Natural Beauty. Built as a defensive barrier in the 8th century by King Offa to divide Mercia from rival kingdoms, this is undeniably a National Trail to cross off your bucket list. In the 12th century, it became the warring border between the Norman Conquerors and Welsh nobles, who built a string of mighty castles along its length.The history along the dyke is immense with many monastic ruins and superb iron age hillforts en route. Enjoy walking on a ridge through the Black Mountains, to the top of Moel Famau, the highest hill in the Clwydian Range and through the rolling landscapes of the Welsh Marches and Shropshire Hills. This long-distance route has it all.
