These mountains form the eastern sector of the Brecon Beacons national park. From Hay-On-Wye on the north to Abergavenny in the south they are right on the border between England and Wales. This is a beautiful area and there are stunning views from the peaks. The famous Offa's Dyke path runs through the mountains and there is a stone circle (Pen Y Beacon) at the foot of Hay Bluff.
Below are a selection of photographs from my visit there.
