This might be a good series along the A465 if you want bag a number in a day. Easy, though some may get muggle riddled at times.
The A465 is a trunk road that runs from Bromyard in Herefordshire, England to Llandarcy near Swansea in south Wales. This stretch between between Abergavenny and Hereford is local to me.
