Offa’s Dyke National Trail

Crossing the border between England and Wales more than ten times in its 177 mile (285km) length, the Offa’s Dyke Path passes through the Bannau Brycheiniog (Brecon Beacons) National Park.

The part of the trail within the National Park, enters near Llathony Abbey and leaves at Hay on Wye, running around 15 miles (about 25km) along the North Eastern border of the National Park, over the Black Mountains.

Of interest

Offa’s Dyke’ itself is a bank and ditch dug by hand in the 8th century for King Offa of the ancient Anglo-Saxon kingdom of Mercia. It was probably intended to divide Mercia from rival kingdoms in what is now Wales, and some sections still form the England/Wales border today.

Offa’s Dyke is one of 15 National Trails for you to explore in England and Wales. ‘
