Llanfihangel-Crucorney sits at the foot of the Black Mountains in Monmouthshire. My top tip is to see the Skirrid Mountain Inn. It is said to be the oldest pub in Wales. You can see the old wood beams and stone walls for free. The village has deep roots in the Welsh past. You can walk the paths of the Offa’s Dyke trail from here. It is a prime choice for a low cost day in the hills. To the north, you can find the ruins of Llanthony Priory. The air is fresh and the valley is green. This spot is a smart choice for a true rural break. It is a peaceful place with clear views of the peaks.
