The walk
Offa's Dyke first shows itself on the cliffs above the Severn estuary, a bank and ditch over a very large tidal range. Then the path climbs onto a wooded escarpment high above the Wye, and from the Devil's Pulpit you look straight down on Tintern Abbey. At Redbrook you cross into Wales, and the Kymin's naval temple looks over Monmouth at the end.
