Brown castle motif and name on white discThree Castles Walk (Monmouthshire)

32 km / 20 miles

A route from Offa's Dyke on the borderlands of England and Wales connecting the three Norman fortresses of Skenfrith, White Castle and Grosmont that formed a defensive line and regulated trade routes. The Walk passes through undulating countryside with hidden valleys and secluded and historic farmhouses in a landscape of mixed farming where hedgerows and small woods have survived to keep the area rich in wildlife.
