Great walk that's pretty accessible for most people to achieve, challenging but doable! The route I took incorporated Lord Hereford's Knob. I published it on Komoot here: https://www.komoot.com/tour/1576268965 And on my blog here (with extra commentary for my own entertainment!): https://weekendwalk.co.uk/route/hay-bluff-walk/

Hay Bluff is a prominent hill at the northern tip of the Black Mountains, an extensive upland massif which straddles the border between south-east Wales and England. The mountain sits at the point where the main northeast-facing escarpment of the Black Mountains meets the northwest facing escarpment, the next peak to the west being Twmpa. The flat summit of Hay Bluff which is marked by a beautiful welsh dragon trig pillar at a height of 677 metres (2,221 ft) overlooks the middle Wye Valley and the book town of Hay-on-Wye.
