Offa's Dyke, Monmouthshire
Offa’s Dyke instils wonder; an 8th century earthwork built by King Offa of Mercia, it consists of a ditch and a rampart, and stretches 177 miles long along the Anglo-Welsh border from Prestatyn to the Severn estuary near Chepstow. You can’t help wondering how they did it, how long it took. The dyke runs through some of the most breath taking countryside with far reaching views, and the diversity of flora and fauna is incredible. If you don’t walk the length of it, go and amble along part of it because its lovely, and there are plenty of places along the way where you can soak up history and culture and stop for a bite to eat.
